Does this mean that the --swarn und --twarn options actually check the
stratum of the best peer of the queried server, not the queried
server itself?
The --swarn and --scrit options (not --twarn), yes.¹

I would be in favour of sending a second query to get the results
right. Correcting the documentation to reflect what the software
really does is only the second best solution.
The current combination of documentation and software behavior is
confusing at best.
And, while we're at it, why is this:
$ /usr/lib/nagios/plugins/check_ntp_peer -H torres.zugschlus.de --twarn=5
--tcrit=4 -v
3 candidate peers available
synchronization source found
Getting offset, jitter and stratum for peer 20cf

NTP CRITICAL: Offset -0,001 secs,
truechimers=5|offset=-0,001000s;60,00;120,00; truechimers=5;5;4;0
$
critical?
--tcrit=4 is equivalent to --tcrit=0:4 and tells the plugin to raise a
critical alert if the number of truechimers is outside the range {0..4}.
Now that you mention it, things are clear. And it is also mentioned in
the --help. But, is the example, -m :5 -n :3 not the other way round?
Thanks for helping.

[Nagios-users] Nagios monitor Windows diskspace
Hi all.
I am currently deploying a Nagios installation to monitor several hundreds
of nodes within our company. I installed NSClient++ on the WXP machines
and configured Nagios to query it.
Standard monitoring plugins work flawlessly (CPU load, Memory usage, NSC++
version), but I can't seem to make the disk space check work.
The error reported by nagios is wrong -l argument and the configuration
is as follows:
define service{
use generic-service
hostgroup_name win-workstations
service_description C:\ Drive Space
check_command check_nt!USEDDISKSPACE!-l c:\ -w 80 -c 90
}
Any clues as why it's not working?

Unfortunately it still returns the same error. Should I enable anything in

[Nagios-users] How to Monitor VMware ESX Server and Storage Units
Hi, up to now, I have usually been monitoring real Unix systems: One installs a bunch of Nagios plugins directly on the target systems and monitors away. Now, I have been asked to monitor a cluster of VMware ESX servers and a fibrechannel-based HP MSA Storage Unit. On the MSA, I cannot install any software at all, and on the ESX servers, I'd rather not install any software since this endangers VMware support just in case something would act up. The site in question is very interested in being able to yell at their vendors if something doesn't work. Both ESX and MSA can speak SNMP, but both boxes are missing information in their SNMP data set that I'd really love to monitor: Both boxes' SNMP sets are missing information about power supply status and whether we have any failed hard disks. I have installed all MIBs that VMware and HP have delivered, and full snmpwalk output does not contain any numerically written OIDs. But there is nothing identifying whether a hard disk or a power supply is even online, and I'd have expected to find a hard disk's SMART info at least partially in the data set which is pollable via SNMP. Are there other possibilities of connecting Nagios to ESX and MSA devices? I'd appreciate your input. Greetings Marc -- - Marc Haber | I don't trust Computers.

[Nagios-users] Service Escalation via Host Group
Hi,
I would like to have host and service escalations for all hosts that
are in a certain host group. The following hostescalation definition
seems to work fine:
define hostescalation {
hostgroup_name norm-notify
contact_groups admins-mail
first_notification 1
last_notification 0
notification_interval 120
escalation_options d,u,r
escalation_period 24x7
}
define hostescalation {
hostgroup_name norm-notify
contact_groups admins-sms
first_notification 2
last_notification 0
notification_interval 120
escalation_options d,u,r
escalation_period 24x7
}
The analogous service escalation definition is ignored:
define serviceescalation {
host_name *
service_description *
hostgroup_name norm-notify
contact_groups admins-mail
first_notification 1
last_notification 0
notification_interval 120
escalation_options w,u,c,r
escalation_period 24x7
}
define serviceescalation {
host_name *
service_description *
hostgroup_name norm-notify
contact_groups admins-sms
first_notification 2
last_notification 0
notification_interval 120
escalation_options w,u,c,r
escalation_period 24x7
}
When a service on a host which is member of host group norm-notify
goes down, notifications go out to the contact group that is mentioned
in the service definition. The service escalation definition seems to
be ignored.
Any idea what might be going wrong?
Greetings
Marc

[Nagios-users] NAGIOS_ environment variables in a notification script
Hi,
I am trying to write a notification script which is called via the
following command definition:
define command {
command_namenotify-service-by-email
command_line/path/bin/notify --mail=$CONTACTEMAIL$
}
To save myself from handing in all macros to the script via the
command line, I'd like to use the macros that are written to the
environment as NAGIOS_foo.
Despite having set enable_environment_macros=1 in my nagios.cfg, the
notification script only sees NAGIOS_PLUGIN=/path/bin/notify.
What am I doing wrong?
I'm using Nagios 3.0.6 from Debian lenny. Any hints will be appreciated.
Greetings
Marc

If that's something you're concerned about, your check_multi will also misfire when the problem is at the uplink for the machines that you're monitoring. Monitoring a gateway and making it the parent is in no way a workaround. An ideal installation for monitoring WAN-connected hosts would monitor your default gateway and make that the parent of all hosts. You'd also monitor the router at each remote site and make that the parent of all hosts at that site. I know all this. My first Nagios experiences date back to when it was still called Netsaint. Of course, the default gateway, the CPE and the COE of the local ISP are monitored. But that's all that can be comfortably monitored since the Internet uses dynamic routing and the paths are subject to change without further notice. Furthermore, a lot of housing providers configure their backbone and access routers to not respond to pings, so it's a challenge to monitor these sites. http://blog.zugschlus.de/archives/770-Nagios,-Parent-Hosts,-and-traceroute-on-the-Internet.html has my thoughts on that matter (thankfully written in English).

[Nagios-users] check_multi advice to check Internet available
Hi,
I am checking a number of servers which are on the Internet, and are
thus likely to become unreachable for my Nagios installations in case
of an outage out there on the Internet. I would like to have a host
which I could use as parent host for all those servers so that I don't
get buried under an avalanche of HOST DOWN alarms should my Internet
go partly or fully down.
I have investigated using check_multi do help me with that, and have
come up with a solution which can help me with this task. I would like
to solicit your comments to that solution.
I have defined a number of hosts which are checked by Nagios proper,
just as normal hosts are. Their individual notifications may be
switched off, but I haven't done so since I like to see what's going
on at least in the start phase. Their hostnames all start with
mh-internet, so I can use a single check_multi config line to pull
them all into a single check_multi check. check_multi is then used as
service and host check on a virtual host called internet, which goes
CRITICAL when more than one mh-internet-foo host is CRITICAL.
Here is my detailed configuration:
/etc/nagios3/conf.d/internet.cmd:
statusdat [ internet ] = /^mh-internet-.*$/:my-defaultping
state[WARNING] = COUNT(WARNING) 1
state[CRITICAL] = COUNT(CRITICAL) 1
state[UNKNOWN] = COUNT(UNKNOWN) 1
Nagios configuration:
define host {
use mh-host
host_name mh-internet
alias internet
address 127.0.0.1
parents localhost
check_command check_multi!-f /etc/nagios3/conf.d/internet.cmd
}
define service {
namemy-internet
use my-service
service_description my-internet
check_command check_multi!-f
/etc/nagios3/conf.d/internet.cmd
host_name mh-internet
}
define command {
command_namecheck_multi
command_line/usr/lib/nagios/plugins/check_multi
$ARG1$ $ARG2$ $ARG3$ $ARG4$
}
define host {
use mh-host
host_name mh-internet-torres
hostgroups mh, ping
alias torres.zugschlus.de
address 85.214.68.41
parents mh-internet
}
define host {
use mh-host
host_name mh-internet-heise
hostgroups mh, ping
alias www.heise.de
address www.heise.de
parents mh-internet
}
define host {
use mh-host
host_name mh-internet-google-de
hostgroups mh, ping
alias www.google.de
address www.google.de
parents mh-internet
}
I am wondering whether this is a valid approach, or whether there
are better solutions for this challenge. If somebody familiar with
check_multi configuration, I would like to know whether there are any
possible issues hiding in my use of check_multi. Any comments will be
appreciated.
Greetings
Marc

[Nagios-users] Log rotation with Logrotate
Hi, Packaging Nagios for Debian means doing things in a way that users might expect them to be done to avoid confusion. One of these expected things is that logs are rotated using logrotate, which allows people to specify, for example, how many log generations are to be held. Unfortunately, to do so, we need to disable nagios' built-in log rotation or we get double rotated logs. Is it possible to tell nagios not to rotate the logs?

If you always only want the 2nd notification, then your approach sounds wrong. You shouldn't suppress the first notification always, but instead maybe raise the number of consecutive failed checks until you throw a hard state, so you do not get too many false warnings. Actually, it is fine (and desired) for the service to show up in the web interface as DOWN, and that the history is correctly written. Greetings Marc -- - Marc Haber | I don't trust Computers.

[Nagios-users] User-defined host/service attributes
Hi,
recently, I was confused by my Nagios reporting a host DOWN event
while the host was alive and kicking. After debugging for a while, I
found out that the host had changed IP addresses and nagios was, of
course, still checking the old address since it was configured to
check the IP address.
To catch such error situations earlier, I'd now like to have Nagios
check that the host name indeed still points to the IP address we're
actually checking.
This is easy enough:
define service {
use my-service
hostgroup_name hostnameip
service_description my_hostnameip
check_command check_hostnameip
}
define command {
command_name check_hostnameip
command_line $USER1$/check_dns --hostname=$HOSTNAME$
--expected-address=$HOSTADDRESS$
}
This, however, means that one has to have the DNS name of the host in
the host_name field:
define host {
use my-linux-host
host_name ipdesc.iface.host.loc.mydomain.example
hostgroups defaultping, snmp-w68, ssh, hostnameip
alias foo server running bar and baz services,
colocated in blu
address 10.1.1.47
parents localhost
}
This is a bit clumsy since our host names are complicated and lengthy.
I'd like to have something like
define command {
command_name check_hostnameip
command_line $USER1$/check_dns --hostname=$CUSTOMATTR$
--expected-address=$HOSTADDRESS$
}
define host {
use my-linux-host
host_name host.mydomain.example
custom_attributeipdesc.iface.host.loc.mydomain.example
hostgroups defaultping, snmp-w68, ssh, hostnameip
alias foo server running bar and baz services,
colocated in blu
address 10.1.1.47
parents localhost
}
If this possible in Nagios2? If not, are there other ideas how to
solve this?
Greetings
Marc

Re: [Nagios-users] NRPE vs NCSA

I'd take a security-based approach.

This is a minus for NRPE. With NSCA, the actual server would initiate the connection to the Nagios host which decreases security exposure. otoh, NSCA has a gap in data flow as nsca_send wants to see the output in a different format than the plugins put out. There are a bunch of shell scripts around that translate between the plugin and nsca_send, but these are like foreign objects in the nagios setup in my feelings. I think that there should be a glue binary written in C that calls the plugin and then hands over the results to nsca_send. Greetings Marc -- - Marc Haber | I don't trust Computers.

[Nagios-users] Two questions about outage processing
Hi, I do not have too much Experience with Nagios, and my Netsaint experience is like three years unused. I have the following issues: (1) When hostA is parent host of hostB, hostA is down, and that outage is acknowledged - why does hostsB show up as Unreachable, Unhandled Problem in the tactical overview? I'd expect the acknowledgement to ACK the unreachable host as well. Otherwise, one would be with a _lot_ of unhandled problems in case of big outages which could mask out more important outages somewhere else. (2) When I see a service in CRITICAL soft state (thus, no notification has gone out yet), I cannot ACK that state (even if I know that the service is going to stay CRITICAL for a while and the problem is already being worked on). IMO, it would be good to be able to ACK even SOFT states. Am I missing something? Greetings Marc -- - Marc Haber | I don't trust Computers.

[Nagios-users] Why the distinction between host definition and hostextinfo definition?
Hi, to me, the distinction between host definition and hostextinfo definition seems artificial, awkward and clumsy - and it prevents some of the more powerful features from being used with the information that belongs into hostextinfo. Hostextinfo doesn't seem to support templates, and it doesn't seem to be possible to set information that is set as hostextinfo from a host group or via wildcards. This makes it extraordinarily hard to - for example - set host icons for the status map, since it needs a dedicated hostextinfo definition setting icon_image and statusmap_image for each host which might have all other properties set from a template. Is there any reason for keeping this distinction and not including hostextinfo into main configuration? Am I missing something here? Greetings Marc -- - Marc Haber | I don't trust Computers.

[Nagios-users] Service on an IP address different from the host
Hi,
some systems I am responsible for have multiple IP addresses, with
services that are not running on all IP addresses. I thus need service
definitions that don't check the service on the host address, but on a
dedicated service address while still being associated to the host
which has a different address.
I have come up with various ways to do this, each of them ugly, but
differently so.
(1)
Duplicate each command definition for a service check like
define command{
command_namecheck_http
command_line$USER1$/check_http -H $HOSTADDRESS$
}
define command{
command_namecheck_http_addr
command_line$USER1$/check_http -H $ARG1$
}
(2)
One other idea I have come up with would be having a thing like an optional
argument, which could be configured like
define command{
command_namecheck_http
command_line$USER1$/check_http -H $IFDEF $ARG1$$ $ARG1$ $ELSE$
$HOSTADDRESS$ $ENDIF$
}
(3)
A different approach (which is what I did back in netsaint days) was a
metaplugin, which allows command configuration like
define command {
command_namecheck_http
command_line$USER2$/modify_address $HOSTADDRESS$-$ARG1$
$USER1$/check_dns_random modify_address
}
which allows service definitions like
define service {
...
check_command check_http
}
which checks the service on $HOSTADDRESS$ and
define service {
...
check_command check_http!192.168.130.5
}
which checks the service on 192.168.130.5.
In the example, the metaplugin replaces the occurence of the string
modify_address with $HOSTADDRESS$ if $ARG1$ is empty, and $ARG1$
otherwise. This has the advantage of having a very straightforward
service configuration, at the price of having a confusing and complex
command definition which does not use nagios standard mechanisms.
(4)
The last approach would be to have host definitions for both IP
addresses, but that would probably be confusing for notification
recipients who are not so intimately familiar with system
architecture.
Which approach would, in your opinion, be appropriate for a new
installation? I am currently inclined towards (4).
What is your opinion?
Greetings
Marc
