Re: [Nagios-users] Nagios as a Service Resiliency Manager
That's an interesting link - but unfortunately I don't think it really covers the situation where a host goes down or becomes unreachable. It may be the case that Nagios is not suitable for this purpose, but I thought I would check on here in case anyone had done anything like this previously.

[Nagios-users] Services on Host Templates
Hi all, If I create a host template, and associate a number of services with it, will hosts which inherit from that template also inherit the service associations? I've tried this out, but it doesn't seem to be working, and I'm wondering if there's something I'm missing. Previously I was using host groups to achieve this, but decided to use templates for my platform specific service checks (so instead of having a Windows Hosts host group with all my Windows specific checks, I would just have a Windows-Host template with the associated service checks which would then be inherited by all my Windows boxes).

Re: [Nagios-users] FW: NDO Utils Question
2009/6/25 Wheeler, JF (Jonathan) jonathan.whee...@stfc.ac.uk: -Original Message- From: Christopher McAtackney [mailto:crist...@gmail.com] Sent: 25 June 2009 14:51 Hi everyone, I have a quick question about Nagios and NDOUtils I was hoping someone could answer. What happens if the database that NDO Utils is using becomes unavailable? (e.g. the server has crashed). The answer depends a lot on whether you are using Nagios v2 or Nagios v3; we are using Nagios v2.11. My understanding is that in Nagios v2, the code that communicates with the event broker module in single-threaded. Therefore a problem with the SQL server can jam up Nagios to the extent that it effectively stops running commands. In Nagios v3, threading has been rewritten and this problem no longer exists. Sorry, should have specified that. I'm running 3.0.6. I'm assuming Nagios will continue to monitor and send notifications as normal, is this correct? In Nagios v2 it seems that almost all activity is suspended when you are using NDOutils and the MySQL server is unavailable; this continues until the SQL server is restored. One solution is to restart Nagios without the broker_module. What about the service check results that would normally be passed to NDO Utils and then stored in the database? Are they queued somewhere? And if so, how is the capacity of this queue defined? If they are not queued, what happens? Will NDO Utils just throw an error for each result it tries to store in the database and fails? Will this affect the core Nagios process? Results passing into the command pipe are stored. The relevant parameters are in nagios.cfg; they are external_command_buffer_slots and check_result_buffer_slots - by default these are set to 4096 (see documentation within the configuration file). Great, that's what I was hoping for. Do you have any experience of setting this buffer to much higher values? Not that I necessarily intend to, but it's always useful to know the effects of pushing the system to its limits. Hopefully someone can provide some insight. Hopefully this has Yes, this has been very helpful, thanks for your answer. Thanks as well Carsten, much appreciated.

This should be there by default, but it sounds like your configuration

Re: [Nagios-users] Centreon
Hi Simon, Sorry, just realised that I had forgotten to reply to you. I got Centreon working perfectly in the end. My centstorage service wasn't running for some reason, but once it started, the graphs started becoming populated with data as expected. I've had it running for about 10 days now and haven't encountered any problems with it at all. One thing I was wondering about though, is if anyone has experience with redundancy strategies for Centreon. With Nagios alone, it seemed simple enough (consolidate the log files), but Centreon's database usage makes things somewhat more complicated. Have you got a strategy in place for synchronising your primary server from a secondary server's database if the primary should go down for any reason? I'll admit I haven't looked too deeply into Centreon's schema, so I'm not sure how feasible this task is. Cheers, Chris 2009/5/7 Simon Finch fin...@stgeorge.com.au: Hi Chris, First does the file /etc/centreon/conf.pm exist ? It should have the database hostname, dbname, dbuser and dbpassword in it. Who owns the /var/lib/centreon directory structure ? The apache user that centreon runs as needs full rights to this directory and the directories below it.

I manually created these directories and granted permission to nagios on them, but still am not seeing any results. Hopefully you've come across something like this before. Cheers, Chris 2009/4/10 Simon Finch fin...@stgeorge.com.au: Chris, Centreon is a very powerful addition to Nagios, so good that I have managed to replace a large enterprise deployment of IBM Tivoli monitoring with Nagios, but only by using Centreon, Nagios by itself wouldn't have stood a chance. I started using it from version 2.0 beta 4 and the doco was terrible or non existent. I am currently using version 2.1 and the doco is still non existent, but the wiki / forum support more than makes up for it. If you compiled Nagios, nrpe, ndo and got it all working then you could easily get Centreon working. I work in IT for a moderately large bank in Australia who has recently been taken over by a larger bank. The new IT top dog is an American who used to run IT for a huge US aircraft manufacturer, he was impressed by what he saw in our NOC / war room. It was Nagios3 front ended by Centreon with management eye candy provided by NagVis, so I truly believe it when I say it's worth the effort because I am in the middle of doing it. If you want more details the feel free to ask as I found a number of traps in the beginning, eg, I don't recommend Redhat RHEL5 for the main server that runs Centreon, I switched to Ubuntu 8.04 , but I still use Redhat RHEL4 5 for the remote satellite Nagios servers.

Re: [Nagios-users] C++ Plugins
2009/4/21 Michael Medin mich...@medin.name:
Hello,
All the built in plugins are avalible as source so it should be pretty
simple to figure out.
The idea is anyways that you fill the buffer passed to the function from the
core.
(this will BTW change in the next major release)
Thanks for the explanation Michael - this should be very helpful.
I'm curious though, what are the guidelines around writing a C++
program to be executed as an external script? I've written a simple
program for checking if the driver name supplied as an arg is loaded
in the system, but I'm not using any of the above glue to do so, I
just make the checks and printf the output and return the result code.
Is this sufficient? Here's the code;
#include stdafx.h
#include windows.h
#include psapi.h
#include tchar.h
#include stdio.h
#define ARRAY_SIZE 1024
int main(int argc, char* argv[])
{
LPVOID drivers[ARRAY_SIZE];
DWORD cbNeeded;
int cDrivers, i;
if(EnumDeviceDrivers(drivers, sizeof(drivers), cbNeeded) cbNeeded
sizeof(drivers))
{
TCHAR szDriver[ARRAY_SIZE];
cDrivers = cbNeeded / sizeof(drivers[0]);;
for (i=0; i cDrivers; i++ )
{
if(GetDeviceDriverBaseName(drivers[i], szDriver,
sizeof(szDriver) /
sizeof(szDriver[0])))
{
if(argv[1] != NULL _tcscmp ( szDriver,
_T(argv[1])) == 0)
{
printf(Driver is loaded);
return 0; // OK
}
}
}
printf(Driver is not loaded!);
return 2; // CRITICAL
}
else
{
printf(EnumDeviceDrivers failed; array size needed is %d\n,
cbNeeded / sizeof(LPVOID));
return 3; // UNKNOWN
}
}
It's based off the code here;
http://msdn.microsoft.com/en-us/library/ms682619(VS.85).aspx
I just drop the compiled program into ExternalScripts and add this to nsc.ini;
[External Scripts]
check_driver = ExternalScripts\Check_Driver.exe driver-name-here
Is this an appropriate way to carry-out this check? It works perfectly
fine so far, but I'm just curious to see if this is a proper way of
doing things?
Cheers,
Chris

Re: [Nagios-users] Centreon
Thanks to all for the replies, I appreciate the offers of help. I was thinking of trying to port Centreon to run against Oracle instead of MySQL. I took a quick skim over the source and it looks like a lot of the database calls are going through PEAR and are fairly generic, so I'm hoping that it won't be overly complicated. The installation scripts look simple enough to port too. Does anyone have any pointers on this idea? I've noticed in some places that NDOUtils is mentioned in connection with Centreon, but I can't determine if it's actually required or not.

Re: [Nagios-users] Nagios and Cacti
With parallel checks in Nagios 3 and some configuration tuning and well-written SNMP checks, I'd argue that Nagios is as good if not a better poller than cactid :). our instance is not huge, but currently we do 7000+ SNMP-based checks in 3 minutes on a dual quad-core Linux-based server. Before PNP I used to use Cacti and Nagios. I like Cacti, but with PNP around I would never go back to that combination again .. Nagios + PNP really does simplify life for Nagios administrators and provides a lot of flexibility as far as how you scale your graphing as your node base grows. - Max Hi Max, Do you all of your SNMP management manually? I'm still learning a lot about SNMP, and was under the impression that Cacti took a lot of the pain out of SNMP management, but I'd be interested in hearing how you administer it in your system just using Nagios + PNP4Nagios if you don't mind?

[Nagios-users] Nagios and Cacti
Hi all, I've been looking into making use of Cacti to act as an SNMP management tool which runs alongside my Nagios instance. Ideally, what I would like to do is have Cacti monitor various SNMP-exposed metrics on my hosts, and then have a service check in Nagios which parses Cacti's results (which I believe are RRD files) and send alerts etc. Nagios itself will still be used for running directly checks for services running, errors in log files etc. Does this approach make sense? One issue that I can think of is the difficulty in keeping the config files of Nagios and Cacti synchronised. I was planning on using Lilac Platform to act as my Nagios config file management tool, but how that is kept in synch with Cacti is a problem. Has anyone ever set up an arrangement like this before?

Re: [Nagios-users] Nagios and Cacti
2009/4/8 Andrew Davis ncc...@gmail.com: And just an FYI from my own experience... putting Nagios Cacti on the same server has been somewhat problematic for us. We have over 400 network devices between switches, routers, WAPs, etc. We also have about 300 monitored servers. Initially I had Nagios and Cacti both on one server with Cacti running via cron every 5 minutes. About every 5 minutes, my shells would become unresponsive for roughly 30 to 90 seconds. Turning off either Nagios or Cacti resolved the issue. Running both seems to have hammered the server a bit (4Gb of RAM, 2 x dual core 2.x Ghz CPUs). We don't integrate Cacti and Nagios, however. Nagios does both trending and alerts of all servers. Cacti does trending only of all network devices/ports. Once I moved Cacti to its own server, all was fine as far as load/latency went. That's useful to know Andrew, thanks. Regarding the trending of network devices - is there any reason why this can't be done by Nagios? I intend to install PNP4Nagios to take care of graphing anyway, but I think it would be nice to have all my monitored resources under the one system (for notifications and ease of administration). Is there some major advantage that Cacti provides when it comes to SNMP monitoring of network devices that cannot be achieved with Nagios and the various SNMP plug-ins available for it (e.g. like these ones http://nagios.manubulon.com) ?

Re: [Nagios-users] Uniquely Identifiable Events in Nagios.log?
Since you almost certainly want to maintain a single process to handle the logged lines, why not just write a tail-like program that parses them one by one as they're written? After all, you'd hardly want to slog through all the log-entries multiple times anyway. With this solution, I find it hard to see a need for uniqueness. should it happen that you still want to be able to uniquely identify lines, I believe a hash over the last 15 or so lines should suffice, assuming it's sufficiently strong (say, SHA1 or something). The chance of running into a collision should be very slim, and if it happens you can just increase the number of hashed lines. -- Andreas Ericsson andreas.erics...@op5.se Thanks for the advice Andreas, I'll take a look into this approach.

[Nagios-users] Uniquely Identifiable Events in Nagios.log?
Hi all, I was wondering if it is possible to configure Nagios to produce uniquely identifiable entries in the nagios/var/nagios.log file? The reason I ask, is that I would like to parse this log file for service check results and perform further processing based on the values discovered there. The trouble is, that as far as I can see, Nagios uses a time-stamp which is only accurate to the second, and so my log files have lines which all have the same time-stamp. Is there a way to increase the accuracy of this time-stamp perhaps? Or any other suitable solution to the general problem of identifying log entries?

Re: [Nagios-users] NRPE vs. check_by_ssh
2009/3/25 Kevin Keane subscript...@kkeane.com: I think you are comparing apples and oranges here, because in most situations that I can think of, the decision is dictated by the network topology. If you are exclusively on a trusted private network, check_by_ssh really doesn't offer any benefits. Conversely, if your topology involves the Internet or some other untrusted network (WiFi), then you wouldn't want NRPE in the first place. The only exception to the above that I can think of is when it comes to deciding between using check_by_ssh over an untrusted network, vs. NRPE through some other kind of tunnel or VPN. But in that case, you'd incur encryption overhead either way, and the comparison is very different from the question you asked. All that said: I don't have any first-hand experience, but I suspect that the impact of establishing 2200 ssh connections in a five-minute span (assuming that you are using a five-minute check interval) is pretty substantial. The main impact actually lies in establishing and tearing down the connections, key negotiations etc.; the encryption during the data phase probably has only limited impact because most checks only transmit a few bytes back and forth. SSH does much better with longer-duration connections when the keys are already exchanged. This is even more true if you have a router-based VPN, because in that case the overhead is offloaded to a different machine. So if you have the option of sending the checks as NRPE through one or a few long-term VPNs: you are probably going to be better off. Of course, in the big picture, your mileage may vary. Firstly, thanks for the detailed explanation of the issues involved in this choice Kevin, it's been very helpful. I'm curious though, could you elaborate on why NRPE is unsuitable if communication with my remote hosts is going to go via the Internet? Is it not sufficient that NRPE uses SSL? This may be more of a network security question than a Nagios one, but I've no real experience in either area unfortunately, so I appreciate any info you can give here.

For example, if I was using check_by_ssh to monitor, say, 2000 services spread across 200 hosts, would I experience significant slowdown on my monitoring machine?

Hi Marc,
I've tried doing as you suggested, but my post check command does not
seem to be being executed for some reason. Do you have any idea what I
might have done wrong? Here is the setup I've used;
In nagios.cfg
obsess_over_hosts=1
ochp_command=host_check
And then in commands.cfg;
define command
{
command_namehost_check
command_line/usr/local/nagios/host_check.pl $HOSTADDRESS$
$HOSTEVENTID$
}
Finally, my simple Perl script to test the output;
#!/usr/bin/perl
open MYFILE, data.txt;
print MYFILE Logging for server $ARGV[0], Event ID: $ARGV[1] \n;
close (MYFILE);
Unfortunately, the script is not being called for some reason. I know
the script itself is working fine, as I've tested it independently.
I've made sure that Nagios is restarted, and the pre-flight check
doesn't report any problems. Any thoughts on what the problem might
be?
Cheers,
Chris

the host_check.pl file, but still no luck in getting it to execute.
Sorry for the monologue here, but I was messing around with it a bit
more and moved the script file into nagios/libexec to see if that made
any difference. It didn't, but in the interim period between moving
the files, updating the configs and restarting Nagios, I noticed that
the following was logged to nagios/var/nagios.log;
[1237804472] Warning: Attempting to execute the command
/usr/local/nagios/host_check.pl 127.0.0.1 53 resulted in a return
code of 127. Make sure the script or binary you are trying to execute
actually exists...
So it appears that Nagios is picking up the command OK, and is at
least *attempting* to execute it, but for some reason, nothing is
happening. Is there some permissions issue here that I'm unaware of?
Thanks again,
Chris

Is host_check.pl executable? If not, try adding /usr/bin/perl or do
chmod 755 /usr/local/nagios/host_check.pl
Hi Andreas, Frank,
I updated commands.cfg to point to the perl binary and granted 755
permission on the scripts as you have suggested;
define command
{
command_name host_check
command_line /usr/bin/perl $USER1$/host_check.pl
$HOSTADDRESS$ $HOSTEVENTID$
}
I performed the pre-flight check and everything was fine, restarted
and no problems in the log, but.. still no execution of the plug-ins.
I'm a bit stumped here as to what else might be causing this
problem...
How do you verify that the program isn't getting executed? Does it
log something to a file with modes 666 every time it's run, or do you
just assume this because it doesn't insert the data into the database?
The program writes out to the text file every time it is run (it's not
connecting to a database yet, this is just proof-of-concept work). If
I execute the program from the command line, it writes to this text
file as expected. However, nothing is being written to the file after
service / host checks, and therefore I can only guess that it is not
being executed by Nagios.

Re: [Nagios-users] Nagios with Trouble Ticket system or Managment System integration
2009/3/23 Florence Luk lukk...@netvigator.com: Dear all, I am new to Nagios and now my company want to try let Nagios to integrate with our new Service Desk system (Management System). For this project our aim is to inject Nagios's alert message to Service Desk system and it can create a 'Trouble Ticket' automatically. So I want to find out basic requirement of Nagios at Nagios side and it how to provide interface (E.g. Application programming interface (API)) for the Trouble Ticket system. I look forward to hear from you soon. Many Thanks. KoKo Florence, Check out Nagiosity ( http://code.google.com/p/nagiosity/ ). It's a Python script which converts the current Nagios status data into XML. It's pretty simple to modify to suit your own particular requirements, and so you just need to write your own program to grab the XML and make the relevant calls to your Service Desk system.

[Nagios-users] Storing Historical Data into Oracle?
Hi all, I'm new to Nagios and was wondering about possible strategies for storing service / host check results in an Oracle database. I'm aware of an Oracle extension to NDOUtils (https://www.nagiosforge.org/gf/project/ndoutils_oracle/) but I believe that it is in a pre-alpha state, which makes it unsuitable for my particular scenario (which will be the production-level monitoring of about 200 business-critical hosts with 10+ services on each). I would be happy to be corrected on this point, but as I said, I'm very new to Nagios and so I'm making some guesses here. Anyway, let's say I decide to go the route of catching the service check results into my database manually, where would be the best place to start? I'm envisioning some sort of script or service which INSERTs into the Oracle database after each service/host check is performed. Does Nagios support this sort of functionality?
