[Nagios-users] Plugin exists?
Hi just wondering if anyone might know of a plugin that does what I'm looking for. The idea is that it would work similar to check_mysql_query, in that it checks the numeric value return by a query against warning and critical threshold values. But instead of querying mysql, it would just cat the contents of a text file. I.e., read the first line and first column of a text file, parse it as a number, and then compare it against the threshold values. It obviously wouldn't be too hard to write a plugin like this, but I figured I'd try to see if one existed in order to not re-invent the wheel. A search through Nagios Exchange didn't turn anything up. But I thought someone on the list might know of one, or have already written one themselves.

Re: [Nagios-users] Best practices for running Nagios across multiple data centers
Thanks much for the suggestions! I'll give Merlin and Multisite some thought. Neither one of them seems to be in the CentOS (or EPEL) repos though, which makes me a little reluctant. I also read up a bit on the Nagios NSCA option too, and it may not be as bad to configure as I thought, so I might wind up going with that. Will run some experiments later today.

[Nagios-users] Best practices for running Nagios across multiple data centers
I've had a lot of experience using Nagios in my previous job, where we used it to monitor numerous hosts and many different types of services - albeit all in the same data center. In my new job, however, I need to set up more sophisticated monitoring, since we have servers located in multiple data centers, with each data center containing a bunch of servers behind a firewall. What are some of the best approaches for Nagios to handle monitoring a setup like this? I'm assuming I'd need to set up multiple Nagios instances - one for each data center - with each one monitoring the servers behind that data center's firewall. What I'm wondering then, though, is how best to tie that all together. Would I need to run another, "main" nagios instance that takes in information from the others? If so, how best to feed the data from the 2nd tier instances into the main one? Passive checks sound like they could do the trick, but if I understand correctly, that would mean I'd need to define each service check on both the main instance (as a passive check) and on the 2nd tier instance (as an active check), which sounds like a bit of a configuration headache. Anyone have any good suggested reading on how to best configure a setup like this? Feel free to RTFM me, though I wasn't able to turn up much of use myself when searching on "nagios multiple data centers".

In my case, I define an "additional detail text" macro on our service checks. It's often hard to determine from the output of a service check exactly what the problem is, since the output is often very specific to the functionality of the service check. Including a plain English "additional detail" message on the alert emails helps make clear exactly what has failed and why. So the way I have it working is that by default "additional detail" is set to blank. But specific services can override this with a small string of text. I probably do this on 30-40% of the (~160) services I have defined. So that brings me back to I'm not sure I see what the performance issue is here. Even if I had 16,000 services defined, we're not talking about that much extra memory required to hold this text. Can you clarify what you see as the issue? Because if I'm doing something that could potentially cause problems, I'd like to understand that. Thanks, DR -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

One of the parms you can specify is to have it check how long ago it wrote something to its log file. We recently had a problem where our Nagios box went down and we never got any notifictions. So I set up another small Nagios instance whose sole purpose is to monitor the primary instance. It has just one service check: check_nrpe calling check_nagios on the main Nagios box to verify that it's up and running.

I can't speak to Nagios v2.x, but at least on Nagios 3.x the command definitions have variable, not hard-coded, parameters. So the command definition essentially winds up being the general definition of what you want to check (e.g., check that a web server is up, using the check_http plugin), while the service definition provides specific details of which machine(s) should be checked using the command and how. (e.g., check that the web servers on boxes 1, 2, and 3 are up, that page /news.html doesn't return a 404, and that the page contains the text "News".) > As a broader question, are there documents that give more of a logical > overview of Nagios, explaining how and why things are broken up and how > they work together?

I think the engine type is set on a table by table basis, not database-wide.
You can see this as follows:
mysql> show create table mysql.time_zone\G
*** 1. row ***
Table: time_zone
Create Table: CREATE TABLE `time_zone` (
`Time_zone_id` int(10) unsigned NOT NULL auto_increment,
`Use_leap_seconds` enum('Y','N') NOT NULL default 'N',
PRIMARY KEY (`Time_zone_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 COMMENT='Time zones'
1 row in set (0.00 sec)
Note the "ENGINE=MyISAM" at the end.

Couple of suggestions:
1) use -f follow in your check_http call to follow redirects. (See
check_http -help for details.)
2) I've found that HTTP servers using virtual hosting work a bit
differently than other HTTP servers. i.e.,
GET /foo.html HTTP/1.0
vs.
GET /foo.html HTTP/1.0
Host: myvirtualdomain.com
So I use 2 different check_http calls for this:
define command {
command_namecheck_http
command_line$USER1$/check_http -I $HOSTADDRESS$ -f follow $ARG1$
$ARG2$ $ARG3$
}
define command {
command_namecheck_http_virtual
command_line$USER1$/check_http -H $HOSTADDRESS$ -f follow $ARG1$
$ARG2$ $ARG3$
}

Sounds like it might be what we'd want. I'm a bit unclear about how this would work in practice though. What I'd want is that when I go check the Nagios "Service Problems" page in the GUI, I'd want to see multiple lines for the service - one line for each of the tags/files that we're having problems with. But if this is configured as just a single (passive, volatile) service, then wouldn't the GUI show only one line for the service, containing details for only the most recent tag/file that failed the check?

Didn't know about the SIGHUP thing. Well, it's good to know that this is a viable option. Still, re-writing a config file seems a bit of a kludgey way to handle this. I'm mulling over another idea, which I'm calling a "rotating" service check (for lack of a better word). Basic idea is: I set up one single service (rather than a service for each tag/file), and each time the service runs it automatically "rotates" to check the next tag/file. If the check fails, then it stops rotating and continues checking that tag/file until the problem gets fixed. Still working out the details, though, and not sure if this is a viable solution for us or not. On the one hand, assuming we run the check every 5 minutes, then the service check would rotate through and thereby check all of the tags within some reasonable period of time. On the other hand, if it hits a tag that fails the check, we'd only get an alert on that particular tag and wouldn't know if other tags were failing the check too. IMO, the ideal solution here would be if I could just submit passive check results for services that aren't explicitly configured in Nagios. But alas, that's not allowed and it fails with messages like "Warning: Passive check result was received for service 'foo' on host 'mysql-dev', but the service could not be found!"

Sounds like a couple of potential issues with it though. By doing this via regenerating a config file, this means that: 1) We would need to manually kick off a "config file regenerate" process each time a user adds/changes a tag/file in our system. It would be much better if there were some way to have nagios automatically pick up the change without any manual intervention. (Though I suppose we could work around this by using a cron job that runs periodically, checks for updates, and then regenerates the config if needed.) 2) If I understand correctly, Nagios loads its config files at startup time and does not re-read them after that. So if I'm regenerating a config file, then that means I'd need to restart the Nagios service afterwards, which is a bit of an onerous imposition. And although again, I could in theory do this in a cron job, I'm not sure I'm comfortable with that. There's the potential for the Nagios service to not start up again successfully, and I don't like taking the risk that this dynamic update procedure could potentially bring down the entire Nagios system. H there's got to be *some* other way to accomplish this, no? Thanks, DR -- Enter the BlackBerry Developer Challenge This is your chance to win up to $100,000 in prizes!

[Nagios-users] Dynamically generated service checks
Scratching my head as to how it might be possible to accomplish a monitoring task I need to do: We have a database table of tags. For each tag we have a process that generates a Javascript file and pushes it out to a CDN. I've successfully created a service check to monitor that the process runs successfully (by using check_mysql_query to verify that a "pushed" date gets updated on the database table). But we also need to monitor that each of the files exists - and in the correct version - over at the CDN, and here's where I'm hitting a wall. What I'm envisioning is a way whereby I could dynamically generate a whole bunch of service checks - one for each tag in the database table. Each service check would then go and download its corresponding file from the CDN, parse it, and verify the version number. In this way, if any particular file was missing or the wrong version, we would get a Nagios alert on that tag/file. However, I don't see any clear way to approach this with Nagios. Near as I can tell there doesn't seem to be any way to dynamically generate service checks. From my reading of the docs, every service need to be explicitly listed in the config files beforehand. I was thinking that perhaps having a cron job that generates passive checks might be a solution here, but again it looks like I would still need to have the service checks defined beforehand in the nagios config files, and couldn't just generate them on-the-fly based on the contents of the database table. Anyone have any ideas on how I could accomplish this file monitoring in a dynamic fashion? (Note that alerting on a file-by-file basis is needed here; it would not be sufficient to have a single service check that monitors and alerts on all of the files.)

Well, assuming that your command definition got pasted correctly, it looks like there's a typo in your command. It should be "-t 45", not "t 45".

Did you add a service on the main nagios host to call the nrpe command
you just set up? i.e.,
define service {
service_description Check remote disk space
host_name the_remote_host
check_command check_nrpe!check_disk
}

Fix would be to either create the directory (and make sure you have its permissions and ownership set correctly) or change your config file to point somewhere else. BTW, on our system (CentOS 5.3) there is no /var/spool/nagios, but rather a parent /var/nagios directory which contains a "spool" sub-dir. So maybe /var/spool/nagios is not the right dir name for your distro? Where did you get your nagios.cfg file from? It'd generally best, I'd think, to take the one that comes shipped with the nagios release you installed and then customize it to your needs so that you don't wind up using a config file from another distro that's incompatible with the layout of your distro's file system. (This is also why I'd think it's generally a good idea to install from a package for your distro, as opposed to building from source, as you indicated you did.)

In my nagios installation those are defined in /etc/nagios/objects/commands.cfg, and the /etc/nagios/nagios.cfg file contains a line "cfg_file=/etc/nagios/objects/commands.cfg" which causes nagios to load that file as part of your configuration.

[Nagios-users] Nagios plugin for monitoring files in a directory?
Just wondering if anyone might have some pointers on a monitoring puzzle I've run into. We have a couple of automated processes - one of them an automated FTP upload, the other an automated log file gatherer - which wind up causing essentially the same result: new files regularly getting added to a disk directory. I need to set up monitoring on this, since if we're not getting new files showing up then something has crashed and our system won't be getting updated properly. Not quite sure how to do this, though - i.e., which nagios plugin would help me get the job done. I've used the check_file_age plugin successfully in a couple of spots. E.g., to verify that a backup process has been run successfully I perform a unix "touch" on a "last-backup-date" file at the end of the backup, and then have the check_file_age plugin check the age of that file. I don't think I can use that plugin & technique here, however, since: a) Each uploaded file has a different (timestamped) name, which I don't know ahead of time. So I have no way to tell the check_file_age plugin which file to monitor. b) Unlike my backup process, which I wrote and was able to alter to touch the last-backup-date file, I don't have control over the external processes creating/uploading these files. I saw there were some rudimentary directory-monitoring plugins over at the Monitoring Exchange site, but they seem like they can only do things like monitor the number of files in a directory vs. a threshold minimum, which is not quite what I want. (I don't really care about how many files there are in the directory.) Anyone have any suggestions on an existing plugin (either part of the standard Nagios release, or available from Monitoring Exchange) that can help here? I'm not afraid to roll my own plugin if needed, but I'd obviously prefer to save myself some work and use an existing one if possible.

Hmmm
OK, well couldn't you just remove the check_command for those hosts?
From the "define host" docs:
"check_command: This directive is used to specify the short name of the
command that should be used to check if the host is up or down.
Typically, this command would try and ping the host to see if it is
"alive". ... If you leave this argument blank, the host will not be
actively checked. Thus, Nagios will likely always assume the host is up
(it may show up as being in a "PENDING" state in the web interface).
This is useful if you are monitoring printers or other devices that are
frequently turned off. ..."

Probably not a coincidence that CDC-Ns1auth starts with CDC-Ns1. Sounds like it's using CDC-Ns1 as a prefix to match hostnames, rather than as an actual hostname. Looks like there's config setting in 3.0 called use_regexp_matching which might control that. Perhaps in your old config file that was somehow turned on. (Or perhaps not defined at all, and on is the default.) Who knows what other old settings you're inheriting too. It's probably best for you to scrap your old config, and start fresh with a new 3.0 config file, then adopt it to your needs (i.e., point it to whatever custom definitions/definition-files you've created).

Might a passive check be the solution here? I.e., instead of having the
nagios box do an active check and try to connect out to the external
hosts, perhaps there's a way to have the external host connect in to the
nagios box periodically and say "I'm still here".

I'm currently doing a login check using check_http, but it's a much
simpler, single-step check. It basically just checks that we can
successfully login with a special nagios username and password by
checking for the presence of the word "Logout" on the resulting page.
(That word only appears if the login is successful.)
define service {
service_description portal login
use our-service
servicegroups http-services
host_name our-host
check_command check_http!-S!-s Logout!-u
'/portal/j_spring_security_check?j_username=$USER3$&j_password=$USER4$'
_ADDL_DETAILThis service verifies that we can log
in to the portal (via: if the login is successful then the string
Logout will be found on the page)
}
Perhaps you might be to accomplish what you want using only check_http
by breaking this up into several different service checks. i.e.: 1)
check that you can log in successfully, 2) check that you can (login
and) hit the service=myservice page, etc.

Re: [Nagios-users] Event Handlers, start a java program, nohup issues.
Perhaps instead of using a java daemon to do JMX queries, you could use the check_jmx nagios plugin. (Available at the monitoring exchange site.) I've been using it in our Nagios system, and it's been working nicely (after some enhancements). I'm in the process of adopting and enhancing the code (neither of the previous 2 authors wanted to maintain it) and setting up a proper home for it on sourceforge (http://sourceforge.net/projects/nagioscheckjmx/). (Don't download it yet until I get the 1.0 release uploaded.) HTH, DR Marco Tirado wrote: > Hello Users: > > I have a problem with an event handler of mine.
