Two things:

- freshness
- volatile services

Freshness determines the timeperiod where a passive checkresult is
considered "fresh" aka current. If the timeperiod is exceeded without
receiving the next passive checkresult, then nagios issues an active
check of that service. Of course you can define anything as active
check you like. I use check_dummy to give me a WARNING "No passive
data received!"

Volatile services reset themselves to an OK state after each WARNING
or CRITICAL. This is useful for things like snmp traps for example
which notify of security impacts and you just want a mail for every
checkresult that is considered a PROBLEM. Like a borderfirewall
notifying you of an ongoing portscan or whatever. Volatile services
are good for one-time notifications of events.

It is, since I make excessive use of it. And it supports it out of the
box - I think even with a default template for that check I think.
So something with your PNP installation must be bogus.

No, you have to activate the check for discards manually via a
parameter.
The four values in question are: Warning, Critical, Minimum, Maximum

Warning and Critical have been set by yourself via -w and -c.
Minimum and Maximum contain the theoretical values
that the interface can give by range [minimum - maximum].
Those values are supplied by the snmpd if mib. They can be overriden
in the remote snmpd.conf if desired.

check_snmp_int is what you are looking for.
Take a look at the extensive parameterlist and you can check for most
anything you could think of.

It's on manubulons website, I don't have it handy - $SEARCHENGINE

2 GiB is the maximum filesize for an ext3 on x86_x64 platforms.

There is no need for nagios to "handle" the perfdata.log. Nagios
only writes perfdata if you request it to do so. This data is _only_
interpreted by external tools, like pnp. They care about truncating
the perfdata once they parsed it. Since you obviously don't use
any perfdata tool - why do you write perfdata logs at all? ;)

I am pretty sure there's no general problem with a 64 bit send_nsca
and a 32 bit nsca-daemon, as I am using this setup massively.
Most of our Oracle servers are RHEL5 64bit and our Nagios is a
RHEL5 32bit. So it must be either a misconfiguration on your side,
or a SLES specific problem. Even though you triple checked it, check
it again - and I'd suppose to just start the integration of that
particular server from scratch again. Maybe you made such an obvious
mistake that even looking 10 times over it would not reveal it to
you. Human beings tend to overlook obvious mistakes they made
themselves - our brain is tricking us there ;)

I'd say the top mistake of all the "I checked it ten times and the
config is correct!"-problems I heard of is: your send_nsca is using
another config then you think it does. Therefor you always check the
wrong config and the real config has a mistake. Just a hint.

Else I can't think of much else, as this setup is running here
without problems. Last question though: are you using a 32bit
precompiled send_nsca on the 64bit system or did you compile
it natively on that system for 64bit?

[Nagios-users] Alternatives to NSCA?

2009-12-11 Thread Sascha . Runschke
Greetings,

does anybody know of a NSCA replacement, which does the job without the 
need
of unsupported libraries? The requirement of libmcrypt makes NSCA a real 
hassle
to use for us, since we have to manually install third party libraries - 
which we really
do not want to. RedHat won't support libmcrypt, as its development is long 
dead.

Any alternatives out there, my google searches didn't come up with 
anything sadly.

Or might it be easier to patch NSCA to use libgcrypt for example, which is 
available
in every distribution?

Regards
Sascha

It depends on how you want to implement the monitoring.
First of all you need to break down the services on a per minute
basis. The number of checks does not matter, but in which timeframe
matters a lot. If you plan on running 5.000 checks with 5 minute
interval - all is cool. If you are running 5.000 checks with 1
minute interval - you will need to tweak your nagios server a lot.

If you are just using nagios for pure monitoring, then you have
more then enough power.

If you are looking for using ndo for visualisation with NagVis for
example and/or graphing performance data with PNP4Nagios, then I/O is
your biggest obstacle.

Using SSDs for a DB is a two-fold sword - they runlike hell, but
SSDs melt in hell ;) It really depends on the quality of the SSDs.
If they are enterprise drives, they should be good to go for 1-2
years until they drop dead. If they are midline drives, you will burn
them quite fast.

The most important thing to have for a nagios installation with
local NDO and/or PNP4Nagios togeter with massive services is a
BBWC (battery backed write cache) of at least 512MB to aggregate
the written blocks and put it on 100% write / 0% read cache.
This speeds up NDO/PNP like tenfold. Read performance is neglectable
for nagios, write performance is all that matters.

I'm running 2.000+ service checks per minute on 5GB, 2x 2GHz QuadCore
machine with 2 local 10K hdd's in RAID1 with a local mysql DB for
NDO, performance graphing of around 1.200 services with PNP4Nagios
and hosting NagVis for visualisation via mysql on the same server.
Average load over 1 month is ~2.7 with peaks going up to load 8 aprox.
Before the use of a BBWC I had an average load of 8 with peaks
around 20 due to I/O retention.

Did you check if you have multiple/old nrpe instances running?
The default init script does not check if the port is already in
use and shows an "OK" even if it couldn't start nrpe because of
a port bind failure.

Does the output of "ps axu | grep nrpe" report a starttime of nrpe
which matches your last restart of nrpe, or is it way older maybe?

No, it states an error in a host.cfg that you tried to use
a template definition that does not exist. I sincerely doubt
that "linux-server" hosttemplate exists in any of your cfg files
used by nagios - or you have a missing closing bracket somewhere
which messes up the configfiles.

It has absolutely nothing to do with the number of hosts you add.
You just have added a host with a bad configuration, which was
clearly showed by the first post you made. Nagios even tells
you what the error is - why don't you check that host definition?

Did you check the MTAs - local and the relay?
Maybe the relay you are using started ditching your mails
because of some strange anti-spam or maybe your host got
throttled by the mailserver because it was sending too much
mails. Just an idea, but I've seen strange setups of "local
relays" being Exchange or Domino servers with really stupid

[Nagios-users] Antwort: Can nagios recognize newly added disks

> are being monitored in Nagios.

No, that's not possible out-of-the-box and I cannot imagine
anyone working on something like this - it's just not feasible.
Nagios itself is independent of the remote machine and its
agent. You can even write your own agent if you want to,
for Nagios it's all the same - just a check that gives
some results back. So to have a mechanism describe by you,
Nagios would need to know about all and every agent out
there and how to remotely check and configure it - that's
out of the scope of the purpose of Nagios.

Though there is the possibility with most remote agents,
that you can trigger an "check all disks that are present"
check. There are 2 turndowns in this though:

- those checks tend to check DVD/CD drives too - bad idea
- if you add or remove disks, the number of results returned
  will differ - making pnp4nagios puke, as it expects always 
  the same number of results

Your turn to choose what you want - both sides suck a little ;)

Did you follow point 5) in the guide?
Nagios installs its html/cgi files into /usr/local/nagios/share.
make install-webconf copies a nagios.cfg file into
/etc/httpd/httpd.conf, if I am not mistaken. A reload
of apache should load that config. As far as I can remember,
debian/ubuntu does not have a /etc/httpd, but a /etc/apache2
directory. Please doublecheck if the apache configfile for
nagios has been created and reload the apache2 server
if you fixed the problem.

Thanks.

You configured nagvis to use the ndo with the name "default",
or to be more exact - it is the default setting.
The database you named in the nagvis.ini does not contain
any ndo instance with the name "default".

There's 2 reasons:

1. You did not install ndo at all
2. You configured ndo to use an instance name other then "default"

The solution should be obvious.

I cannot directly compare it, since I do not know anything about
iPhone development, but I can't believe that the BB SDK is so far
less powerful compared to the iPhone SDK.
Which SDK did you check out? BB offers 3 (or was it 2?) different
SDKs for the 3 different methods of coding for BBs.

- the web applications: very, very easy, but surely also very limited
- MDS applications: easy to code, but still more powerful then
  webapplications
- pure Java applications: can do basically everything you
  want them to do

If you already have a Java application, it shouldn't be too
hard to port it to Blackberry I think?

You can't unless you are already logging performance data into mysql.
Nagios itself does not log performance data at all.

Use the NDO Utils. Google is your friend.
Otherwise you need to dump the RRD databases of PNP and import
that into mysql with a script - but that script you need to write
yourself I guess.

> - PNP4Nagios: How do I tell PNP4Nagios to pull its performance data

You can't. PNP4Nagios stores its data in RRD databases. There is no
way to push it into a mysql DB and on the other hand, it wouldn't make
sense either for PNP.

> I have found very little information about this, so any help is 
> greatly appreciated.

I guess that's mainly since you misunderstood something. Nagios
naturally doesn't have the need a mysql backend. Nagios does have the
NDO Utils, which store realtime and historical data in a mysql DB, but
that's only for third-party applications that need that data. Mainly
there is nagiosgrapher and nagvis, maybe NagiosBP.

On a sidenote: it's a bad, bad idea to have critical services
running on your monitoring server. Service monitoring is always
stressing the machine when your installation is not exactly small
and you check often.

Conclusions:

- get a bigger server
- get faster storage
- move the other services from your nagios server

Easy answer: you can't.

If you want checks to happen at predefined times and in a

Because ssh has way more overhead especially because of the way
how the ssl connection is handled. Therefor a check_by_ssh check
takes longer then a check_nrpe check. This _is_ significant if
you are running 2k checks per minute like me and some other people.
Lots of check_by_ssh checks slow down the machine by a big degree
and check latency will skyrocket.

Configure your webserver accordingly.
It's hard to guess how you set it up to serve multiple domains, but
the mechanisms apply when you want to configure the access to nagios.
Most likely you have a /etc/httpd/conf.d/nagios.conf which defines
scripts and aliases. Those are apache-wide defined and not bound to
a special virtualhost. Move the definitions of nagios.conf inside
the virtualhost definition of your choice and nagios will only be
served there.

Yes, use the source luke and edit the index.html.

Do you have the mysql-devel and mysqlclient-devel packages
installed?
What was the exact output of ./configure?
Did you issue a "make distclean" before retrying to wipe out
the configure cache?

You have to be a bit more exact on your problem then just
"it doesn't work" ;)

Well, that's up to you to decide.
You obviously told nagios to run no more then 400 checks at a time.
Nagios now reached that limit and delays further checks, so no more
then 400 processes are forked.

I don't know why you set that limit, do you? ;)

Take a look at the nagios.cfg and the "max_concurrent_checks" setting.

That your nagios is running inside a virtual machine would have been
a nice information I guess ;)
Nagios doesn't perform overly too well inside a VM - actually you
could say it runs horribly if you pass a certain point of checks
per minute. The virtual system bus isn't able to cope with the
throughput then.

The strange thing is that the error looks like your system is running out

but actually that cannot be, since it's x64... could you please post a

Your Nagios doesn't have a working DB connection at all.
Please do a "tail -f /usr/local/nagios/var/nagios.log" while
executing a "/etc/init.d/nagios restart" on another console.
Watch the nagios.log for entries regarding to ndo.

I'm unsure how you want to "implement" the ABD of RRD.
Do you just want to use it to visualize anomalities, or do you
want nagios to notify you if an anomality occurs?
The pure visualization is pretty simple, I've already done that. Sadly the 
results
were a bit - disappointing.
After evaluating the graphs with aberrant behaviour detection we came to 
the conclusion,
that about 99% of our nagios checks cannot be used to detect real 
anomalities.
Things like diskfree, CPU, network i/o, disk i/o and the such do not 
follow strict patterns
and are unpredictable most of the time. The only things we found ABD to be 
helpful with
were monitoring temperature and humidity in our datacenters.

PNP4Nagios can be easily used to implement ABD, all you have to do is 
change
the rra.cfg to reflect the necessary aberrant behaviour detection RRAs. 
But
keep in mind that you have to make those changes to the config _before_ 
the
first RRD gets created, since you cannot add RRAs to existing RRDs - at 
least
not without major knowledge in manipulating RRDs (say: export dump and 
manual import
with selfmade scripts)

Nagios is not responsible for how your smtp mail is dispatched.
Nagios passes it to the local submit agent (most likely sendmail)
and is done with it. It's up to the MTA (sendmail) to decide what
to do with a mail. If you want it to relay mails to an external SMTP,
configure sendmail to do it for you -> check the smarthost setting.

Well, that would mean you have to allow a DMZ machine to initiate
connections into your internal LAN - which is a very, very, very bad
idea...

[Nagios-users] Antwort: Re: too much notify

2008-12-15 Thread Sascha . Runschke
Hello Alejandro,

first of all: please do not "toppost" and "fullquote" the messages.
It's considered rude and makes reading and understanding your message
harder then necessary. Thanks for your understanding.

Second: You have misunderstood something.

You posted a service definition.

> ---
> define service{
[snip]
> }
> ---

But you then posted a host problem notification.

> at 13:20pm
> Notification Type: PROBLEM
> Host: cn016
> State: DOWN

Service problems and host problems are two different things.
The fact that you have a PING service might be the reason
you misinterpreted the mail. A PING service is most of the time
not necessary, because Nagios will ping the host anyways
via the check-host-alive command.

> How i can make to receive only one alert?

Check your host definition for the notification_interval.

Sascha

The possibilities of the nagios status map are rather limited
and it's hard work to adjust all the hosts manually so it doesn't
look as stupid as it does if you have a big environment.

Check NagVis out. It's a standalone webapplication, which uses
NDO as datasource to display the nagios status. It's full
configurable and you can place the hosts/services via drag&drop ;-)

Does the user, which you used to authenticate to the apache, have 
permission
to view the other 2 hosts - that is, is he a contact of those hosts?

I'm a little bit unsure you understood how "load" is to be interpreted
on *nix machines. You should probably dig into G**gle for some
and search for information. Your definition is senseless.

Hm well, what's wrong with "./check_procs --help"?
You supplied -a, which needs a string as argument, which in turn you
didn't supply. Please read the docs and --help first, before
trying more plugins with "not so well chosen arguments". ;-)

Those kind of problems usually arise from wrong return values of
plugin scripts. NRPE passes the return value of the check plugin
back to nagios and Nagios interprets it as OK/CRITICAL/whatever.
The actually string output has nothing to do with what Nagios will
show as state.

So I would assume that Solaris 10 zone does something really
strange with the exit values of the plugins. Does Solaris have
/bin/sh with "$?" - if so then please run the check locally and
issue an "echo $?" right afterwards.

Sascha

FreeBSD does not have a root group, like Linux systems.
Edit the Makefile of your nagios source and replace:

INIT_OPTS=-o root -g root

with

INIT_OPTS=-o root -g wheel

I don't know very much about the BSD initscripts either, so if they are 
not SysV style,
then you need to edit INIT_DIR too.

Hope it helped.

Ah, my bad - I've read your configuration too hastily.
But you do know that this means you have actually 3600
more checks to do then without this dependency, as 3600
checks will initiate a dependency check on the check_uname
service if your predictive caching window is not big enough.
Should your machine be able to handle 3600 more active checks
that easily or do you have a big enough caching window?

Excuse me, but what would that be good for?
Why do you have _every_ nrpe check be depending on _every_
other nrpe check? I cannot make out _any_ scenario where
this would make any sense.

Did you configure this by accident or by intend?

If you think twice about your question, you should notice the

There is no real reason to check for snmp, other then polling
specific oid's to monitor something. If you do not check any
snmp oids - why do you want to know if snmp is running?
Besides, you could just do a check_udp on port 161, then you'd
know if there is something listening.

Most likely exim or postfix is installed - depending on the debian/ubuntu
version, but not correctly configured. Please have a look into it and
configure it for using your local mailserver as relayhost.

I can't really believe the 2 scenarios you are describing.
You say the first simulated down comes immediatly and the next simulated
down takes 15 minutes to notify... that can't be.

Looking at the history you posted it seems quite obvious to me that
you have defined 10 retries for the host. With a retry interval of
roundabout 1 minute (which is sometimes delayed due to scheduler latency)
you end up with 10-15 minutes until the host enters a HARD state and
nagios generates a notification.

Your setup is working exactly how you configurated it.
If you need immediate notifications, reduce the retry_checks to 1.

Sascha

Hello Ryan,

first of all: please to not top-post and do a fullquote at the same
time. It's considered rude on mailing lists and it's unnecessary
waste of bandwidth and makes mails hard to read, as I do not know
if you posted between the lines too.
Either please don't quote at all, or post your replies between the
quotes, like I do usually for example. Thanks for your understanding.

Ok, that seems like a possible explanation. If you have a lot of checks,
which are expected to time out, then you will have a lot of "hanging"
processes waiting to quit. There is really nothing you can do about
it, but lower your timeout value.
Another option is to refrain from using check_ping, but use check_icmp
instead. check_ping is a wrapper script, which calls /bin/ping and
parses its output. Therefor you have the extra "sh" fork. check_icmp
is a plugin with native icmp implementation and doesn't require
the extra fork. It's faster, less bulky and todays check of choice
for host checks - at least for intranet hosts in my opinion.
WAN hosts are another thing though... but that might be my personal
opinion only.

There is really no way to solve that "problem". It is like it is.
Question is rather: how can it be, that you have 57 hosts, which
are down for an extended period? I do not know your environment, but
it seems questionable to me, why such hosts would deserve a monitoring.
But that's up to you to decide.

Sascha

These thresholds were never meant to be any upper limit, the maximum 
number
of concurrent checks your box can handle solely depends on your hardware.
See it more like an "if you have a nagios installation which produces
that many concurrent checks - then you should know by now how to
change this behaviour" ;-)

But then - I fail to see how your setup with 322 host and only 35(?) 
service
checks could produce that many processes. Maybe it'll be a good idea to
doublecheck what's going on there.

Well, obviously you turned off the check_external_commands in the 
nagios.cfg.
Set it to 1 and restart nagios.

Btw: this would be an excellent time for reading the nagios documentation, 
too...

How about configuring your contact for sms for just receiving
criticals and recoveries? You won't get warnings and their
recoveries then...

3.0rc1 works with NDO 1.47b, but I fail to see why someone would
want to use an outdated pre-release version...

To me it looks like the nagios->ndo connection works,
but the ndo->mysql connection not. Check your ndo2db
Logs if there are any problems reported. If not, try to
enable debuglogging in ndo2db.

Making the Nagios Status Map pretty is quite strenous and time consuming.
And everytime you add a new machine it might break your layout of absolute
coordinates - time you could really spend better.

Take a look into NagVis: http://www.nagvis.org
Imho it's by far the most advanced tool to visualize Nagios.

It's a NSCA bug as far as I know. I had the exact same problems and
updating to 2.7.2 solved all issues for me it seems as it did not turn
up again ever since then.

Are you running NSCA 2.7.2 already?

Actually that's unnecessary double work. You can easily use Nagios
for trending and graphing, without much extra work. Using the outputs
of the Nagios checks, you can add PNP or NagiosGrapher or whatever
to graph those things. Why put up the extra workload to have a second
environment to administrate, when you can have it all in one?

I wrote a plugin for parsing mpstat output:

([EMAIL PROTECTED]) /root (1)>/usr/lib/nagios/plugins/check_mpstat.pl 
Total: 29.78% User: 12.67%  System: 5.59%  I/O: 11.52% | usr=12.67%;80;90; 
sys=5.59%;80;90; io=11.52%;80;90;

Sadly it's not really rocksolid yet, as I wrote it when the need came up
to closely monitor an Oracle server and therefor it's fitted for that 
machine.
I am unsure if it will work on any other platform but RHEL4 x86.
I hope I'll get the time sometime soon to get it straight...

There are no two nagios instances running at this timefor sure, despite
those that the root nagios process forked by itself...
But as already said, I do not care that much for the initial state
logging, but for the strange empty entries from 01.01.1970.

I don't mean to be rude, but do you really think someone still cares
for Nagios 1.3 and its problems? ;) You should consider upgrading to a
supported version.

Since that was no help to you, I'm sad to inform you that we cannot
help you either, since we do know nothing about your configuration.
Might it be that the sms contact has a different notification_period
defined? All we can do is wild guesses.

No Path inside the check environment?

Won't work without a path. Try using the full path to grep and touch.

Well, I'm rather thinking: How the hell can Nagios lock AD accounts?
If you do not describe what you did at all, I doubt anyone can help
you. I have absolutely no clue why someone would want to define
some $USER#$ or whatever and what it would have to do with AD ;)

Please be more descriptive in your posts to the list. We cannot
guess what you are doing, hence we cannot tell you what might be
wrong with your setup.

First of all: Problems with Nagios itself do not belong to the
nagiosplug list, this one is about the plugins for Nagios.

Second: What does your Nagios have to do with your AD at all?

Sascha

a)
- Use Escalations

b)
- Define the service as 24x7
- Define the period inside the email contact 24x7
- Define the period inside the sms contact 6-24 (you need to create a new
  timeperiod for that)


I'd choose a) as it leaves you with more flexibility for the future.

From the nagios documentation:

External Command File

Format: command_file=
Example:command_file=/usr/local/nagios/var/rw/nagios.cmd

This is the file that Nagios will check for external commands to process.
The command CGI writes commands to this file. The external command file is
implemented as a named pipe (FIFO), which is created when Nagios starts 
and
removed when it shuts down. If the file exists when Nagios starts, the 
Nagios
process will terminate with an error message. More information on external
commands can be found here. 


Need more hints? ;)

It depends on how you configured the max_check_attempts of the service 
checks.
Did you happen to have it set to 1?

It's kinda hard to guess...

After looking throgh the config, I cannot find any culprits which would
cause such behaviour. Maybe you have some bogus notification commands?
The "Problem: ... is UP" doesn't seem to make sense to me and does not
correspond to the default configuration. Recovery alerts shold start
with "Recovery: ..."

Please post your host-notify-by-email command definitions.

I'm running nearly the same set, just missing nagiosla, on RHEL5.2.

Machine is a HP DL360 Quad-Core E5405  @ 2.00GHz with 5GB Ram.
Local 10k SAS hdd only, no SAN, local mysql.
400 hosts, 1500 servicechecks.
1400 servicechecks are scheduled every minute, 100 once per day.

I do get roundabout 1100-1200 checks throughput each minute,
averaging 80% of the expected checks each minute with a very
good latency.

Check Execution Time:   0.01 sec10.02 sec   0.417 sec
Check Latency:  0.00 sec7.19 sec1.623 sec 

I've done extensive performance tests and in summary the best
practices to speed up things:

- RAM, RAM, RAM. Both for mysql (see below) and for increased
  filesystem buffers.

- Reserve enough memory for mysql to keep things buffered as
  long as possible:

  I'm currently using these settings:
 
  innodb_buffer_pool_size = 1024M
  innodb_additional_mem_pool_size = 64M
  innodb_log_file_size = 512M
  innodb_log_buffer_size = 64M
  innodb_flush_log_at_trx_commit = 1

  Beware: this will spike up mysql memory usage to nearly 2GB virtual
  and roundabout 1GB of resident memory.

- use npcd for bulk processing performance data for pnp. Direct
  injections for each performance result will stall your checks
  and result in huge check latency

- set "data_processing_options=4061953" in your ndomod.cfg
  By default ndo parses and injects every event from nagios,
  which results in unnecessary mysql queries and bloats the
  database over time - even more slowing down ndo since it
  automatically purges old data. With this option you won't have
  any aging data and the database only holds realtime info
  Attention: This setting is totally perfect with Nagvis, but I have
  no clue if nagiosla needs ndo and what information - so double check
  that.

- I'm using "use_large_installation_tweaks=1" too, but I'm not sure
  if it would have any impact on your scenario.

- I've manually built an SQL index over some tables for ndo, but I
  doubt it would have much impact on your scenario either.

Thanks a lot Andreas - this was exactly the reason.
Since I use a self-hacked version of Monarch for administrating nagios 
3.0,
I just missed the fact that it activates stalking for hosts by default on
templates...

[Nagios-users] Massive HOST UP alerts in nagios.log for no reason

2008-05-28 Thread Sascha . Runschke
Hi all,

ever since I started building up our new nagios environment under nagios 
3.0, I noticed that my
logfile contains massive amounts of HOST UP alerts - even though the host 
was never down before.
Actually I seem to have this log entry each time a host is checked, I 
guess they get checked for
the predictive and cache host tests. But sadly it's getting a real pain, 
since the logfile is growing
so big, that my firefox even crashes when I try to view it with the 
webinterface.
My daily nagios.log has the massive amount of roundabout 110.000 entries 
each day - which is
little bit too much for its 400 hosts / 1600 services imho. Nearly the 
same checks (actually a few
less, but whatever) produce roundabout 10.000 lines of log on our nagios 
2.11 server each day.

The culprit seems to be:

[EMAIL PROTECTED] archives]# egrep "HOST ALERT:.*UP;HARD" 
nagios-05-28-2008-00.log  | wc -l
97716

So I have 97716 entries each day looking like:

[1211844162] HOST ALERT: sw-00-o2;UP;HARD;1;OK - 1.2.3.4: rta 1,069ms, 
lost 0%

with the hostname of course being always different - every host comes up 
every minute.

Does anyone have any clue if this is intended behaviour or what I may have 
done wrong?

S

[Nagios-users] VMWare Infrastructure monitoring

2008-05-28 Thread Sascha . Runschke
Hi all,

I've recently spent some time again on thinking about our VMWare 
Infrastructure (ESX clusters) and
its monitoring. I'd like to hear some opinions from the list, how others 
implemented the monitoring.

Currently my setup is as follows:

- 3 ESX clusters with 6 hosts each
- 100 VMs per cluster

My current approach:

The first cluster for example is defined as host "essesx-cluster" with 6 
services ESX01, ESX02, ESX03.
Those services are check_icmp checks on the IP of the service console of 
each ESX host.
The hostcheck of the "essesx-cluster" host is then:

check_cluster --service -w 1 -c 1 -d 
$SERVICESTATEID:essesx-cluster:ESX01$,
$SERVICESTATEID:essesx-cluster:ESX02$,$SERVICESTATEID:essesx-cluster:ESX03$,
$SERVICESTATEID:essesx-cluster:ESX04$,$SERVICESTATEID:essesx-cluster:ESX05$,
$SERVICESTATEID:essesx-cluster:ESX06$ 

All VMs are childs of their corresponding cluster host.
The ESX hosts itself are not monitored as hosts, just as services of the 
cluster.

What do you think about that approach? Is it sophisticated or rather dumb? 
I have to admit that I am
a bit clueless right now, as it looks quite weird. Does anyone see any 
problems with that appoach?

/discuss

regards
Sascha

Not trying to be rude, but did you bother to read the documentation at 
all?
From your questions to the list, I get the impression that you did not.

check_nt --help should tell you, that the "-l" switch is used to
supply the driveletter to check. The "alias" directive in the nagios
config is just for pure cosmetics, it has no actual meaning for nagios
itself, it's like a comment field for the host.
So you need to change the commandline of your second servicedefinition
from "... -l C " to " -l E "

I am using Monarch with v3. It doesn't officially support it, but with
some stunts, you can make it work - that is if you do not mind to miss
out the new features of v3 with custom attributes and such.

You do not integrate MIBs into Nagios.
Since check_snmp uses basic GNU tools (snmpget) to fetch its
information, you only need to integrate your MIBs into the
standard snmp environment in your *nix installation.
check_snmp includes the -m ALL switch, which includes all
installed mibs by default.

man snmpget && man variables

I actually have considered this, but found sadc not feasable for
my intents. I am not interested in general iowait, but more in
bandwidth usage of actual devices. Most of our high load servers
have 3 SAN connections and it's important to know _which_ of those
is under high stress and especially the performance data of
those statistics to determine upcoming problems.

At least I haven't been able to get sadc to log bandwitdh and
throughput for each block device individually. sar in interactive
mode is capable of doing it via "sar -dp 60 1" for example.

Another problem that arises when using sadc is the problem that
the scheduling of nagios is non predictable. I cannot garantuee,
that nagios will poll the information once a minute for example.
I cannot garantuee that nagios won't run the check twice in a
longer checkperiod. The biggest feature of using it via send_ncsa
passive checks, is the fact that I can inject the data when I want
to - with perfect timing.

But when using sar interactively, it's basically just a iostat -dp,
which does the average calculation at the end - something my plugin
already does ;)

I'll put out our options in an abstract way:

a) using sadc/sar:

Have $script run by cronjob.
Run active checks from nagios.

b) using my passive plugin.

Have $script run by cronjob.
Let $script send output to nagios.


In my opinion b) sound more appealing to me, since we have full
control of timings. I do not see any benefit of using a).

But maybe I am missing something - I am open to suggestions and
ideas ;)

To my knowledge, there is no such plugin available at the moment.
As I already wrote, I am currently working on one though ;)

On a sidenote: Forget about running it via nrpe, this would be flawed
by design. Since iostat only reports bus usage in realtime and has no
means of displaying averages, it would mean you would have the usage of
your bus for the time of 1 second every minute (at best). Doesn't help
at all. Trust me, I excessively tried things when messing with iostat
parsing on our high load oracle servers. ;) You need to call iostat
with multiple checks - the longer the better - but then it means you
would have to  run iostat for like 30 seconds or so -> plugin runtime
is 30 seconds too then! That means that check would have a high
delay/latency, which is overall a bad idea. My solution so far is
to run the plugin via cron and report output via nsca, this gave
me the best results.

Sadly my plugin is currently not in a state to be released, since it
is yet too far narrowed down to monitor our special oracle environment.
I still need to make it more configurable and such, but I expect to
be able to release it in the next 1-2 weeks - depending on how much
time I have spare to work on it.

Could you change it into a perl plugin? ;)

I'd like to give it a try, but I cannot install python on all our servers
now, since we don't use that at all. Pity.

"Usually" there is no such thing as "best way" in a custom scenario ;)

For linux I wrote my own plugin to parse iostat output, but it's not yet
fully finished.

For Windows you might want to look at the WMI Scripts from... uhm... it
was op5 I think. Google is your friend. You can embedd those scripts
into nsclient++ and use a custom nrpe check then.

[Nagios-users] Nagios 2.x configs compatible with 3.x?

2008-02-14 Thread Sascha . Runschke
Hi,

I'm wondering:

is it possible to use 2.x configs for hosts, services and the like with 
3.x without problems?

The scenario is the following:

I've monarch running now with some spooky config, so it doesn't overwrite 
nagios.cfg and
cgi.cfg. Those are fully 3.x configured and contain the needed parameters. 
Yet I'd like
to keep monarch for configuring the hosts, services, timeperiods, 
escalations and such.
Of course I've tried it already and it "seems" to work. I still wonder 
though, if I have to
expect any problems sooner or later? I know that I won't be able to use 
the new
3.x features, like integrated extinfos, inherited contactgroups, multiple 
templates and
the like - but I can live with it for now. I haven't tried if escalations 
configured with
monarch will work, but I'd expect so.
The problem is that $CTO says: I want a webconfig for nagios, no excuses!
And I don't want to keep using 2.x anymore, since the performance of 3.x 
and
especially the polished parent-checking are extremely valueable to us.

So, does anyone have any objections against using 2.x configs with 3.x?

Do I have to expect any problems Ethan?

Thanks for any input,

S

Write a wrapper script, which calls both processperfdata from PNP _and_ 
PerfParse with
the parameters from nagios. Then use that processperfdata script from 
within nagios.

What does the defition for the contacts in the beick contact_group look

Uhm, there is nothing special you need to do to make nagios run with 
https.
https is only a webserver configuration, nagios does not make use of 
absolute URIs - so it doesn't care for http or https.

Take a look at NSCA, you'll find the framework on the nagios homepage.

[Nagios-users] Problem: Sending RECOVERY to contacts which have never got WARNING/CRITICAL notifications

2007-07-06 Thread Sascha Runschke

Hi all,

it has been a while since I last wrote something, but Nagios usually just
works perfect ;)

But lately I stumbled over a small problem, which is really annoying. I'm
using Nagios 2.9.

Scenario is:

Servicecheck goes WARNING during the night (escalation says: no SMS, only
MAIL!) -> WARNING Mails are dispatched
Servicecheck goes OK during night (escalation says: SMS and MAIL are both
ok) -> RECOVERY Mails + SMS are dispatched

I really wonder why Nagios sends RECOVERY though Channels, which never
received
the WARNING/CRITICAL. If nothing changed in the policies lately, Nagios
should only
send RECOVERY to someone who got the WARNING/CRITICAL at first.

The WARNING are send via Mail to NETWORK-CONTACTGROUP-MAIL, which contains
a
set of contacts for Mail. The RECOVERY instead is send to
NETWORK-CONTACTGROUP-SMS,
which contain a different set of contacts, that carry the pager number.
Again: we have 2 different
contacts for each person, one for mail, one for SMS! So the RECOVERY goes
to a contact
that didn't even receive the WARNING/CRITICAL in first place - that's what
disturbs me most,
despite the fact that unwanted SMS at 5am are quite disturbing too...

Did anyone else notice this lately?
Is anyone able to explain that behaviour to me?


Config of the checks is as follows:
(I have resolved all template inheritance to make it better readable - of
course we do not
set up things like that in real ;))

define service {
namegeneric-SNMP
max_check_attempts2
normal_check_interval 1
retry_check_interval  1
active_checks_enabled 1
check_period  24x7
passive_checks_enabled  1
parallelize_check   1
obsess_over_service   1
flap_detection_enabled1
process_perf_data   1
retain_status_information 1
retain_nonstatus_information  1
notification_interval 60
notification_period   24x7
notification_options  w,u,c,r
notifications_enabled 1
stalking_optionsw,u,c
contact_groupsNETWORK-CONTACTGROUP-MAIL
host_name   USV01
service_description   USV_TEMPERATURE
servicegroups SERVICEGROUP
register  1
check_command
check_snmp!my-secret-community!iso.3.6.1.4.1.1356.1.2.4.0!1!:37!99:42
notification_interval 10
stalking_optionsc,w,u
notification_options  c,w,u,r
}


Naturally all notifications get overridden by our escaltion settings:

#
# Daylight: SMS every 10 Mins at first occurence
#
define serviceescalation {
nameesc_service_verfuegbarkeit_1_1
first_notification1
last_notification   0
notification_interval   10
escalation_period daylight_hours
escalation_options  c
host_name USV01
service_description USV_TEMPERATURE
contact_groups  NETWORK-CONTACTGROUP-SMS
}
#
# Night: SMS once at the second occurence
#
define serviceescalation {
nameesc_service_verfuegbarkeit_1_2
first_notification2
last_notification   0
notification_interval   600
escalation_period night_hours
escalation_options  c
host_name USV01
service_description USV_TEMPERATURE
contact_groups  NETWORK-CONTACTGROUP-SMS
}
#
# 24x7: Recovery via SMS (only fires when SMS has been dispatched before)
#
define serviceescalation {
nameesc_service_verfuegbarkeit_1_3
first_notification1
last_notification 0
notification_interval 600
escalation_period 24x7
escalation_optionsr
host_name USV01
service_description USV_TEMPERATURE
contact_groups  NETWORK-CONTACTGROUP-SMS
}
#
# 24x7: Always receive notifacations via Mail too
#
define serviceescalation {
nameesc_service_verfuegbarkeit_1_4
first_notification1
last_notification 0
notification_interval 10
escalation_period 24x7
escalation_optionsc,w,u,r
host_name USV01
service_description USV_TEMPERATURE
contact_groups  NETWORK-CONTACTGROUP-MAIL
}


I'd appreciate any light sched into this matter.

Regards
  Sascha
