I found it once on the web by means of googling it.How do you run a command, from nrpe.cfg, to make sure that it works?For instance, command[check_total_procs]=/usr/local/nagios/libexec/check_procs -w 150 -c 200
View 1 RepliesFirst I don't know Nagios. I've been left with a fairly large(350 servers, 750 services) Nagios system installed. I've scraped and googled till I'm blue in the face. The Nagios folks have been less than helpful in that they tell me I need to figure it out myself. I've tried for four days to *figure it out myself*.
I have an entry in the checkcommands.cfg file:
# 'check_dns_external' command definition
define command{
command_name check_dns_external
command_line $USER1$/check_dns -H $HOSTNAME$ -t 60 -s 4.2.2.1 -a $HOSTADDRESS$
}
First, I don't understand what this command means and does. Next, I don't understand how to manually execute this command. I do know that the command in automatic mode has stopped working as Nagios tries to execute and I get an error message on the Service Status Types: Nagios alert page. The alert doesn't come with any regularity as to time of day or availability of resources. Apparently, this Nagios command is executing randomly. It is waking me up several times a night and several times a day as we page out alerts via email.
I'm lost. Aside from bouncing the entire Nagios stack, which is not possible right away as this is a Production system, is there any way to manually execute the offending line described above? Again, I've asked the Nagios folks and they have declined to answer.
I am running Nagios on CentOS. Everything is working fine, all my clients status is ok. One thing which is confusing me is "Root Partition WARNING" on my own server which has Nagios installed. I think that these things are controlled by nrpe, which is installed in clients servers. what i want to know is how i manage my own server, in which config files i have to make changes?
View 14 Replies View RelatedI have an existing Nagios installation from before I started working here. It seems to be working well but my boss has just asked for a report of what servers and the associated processes/functions are being monitored. Is there any way to generate this report other than going through all the Nagios configuration files and putting it together manually?

Code:

Yes I have tried exporting my paths and variables aab still will not run my script. 'm sure I am doing something wrong.I have a shell script which runs a jar file. This is not working correctly. After reading around I have read this is commonly due to incorrect paths due to cron running via it's own shell instance and therefore does not have the same preferences setup as my profile does.here is what my script looks like today after several modifications:

View 14 Replies View RelatedTrying to monitor mysql 5.0.77 with nagios 3.2.1 under CentOS 5.4. Everything with nagios has been running without a hitch for me, however, when I added the following to /etc/nagios/objects/localhost.cfg to try to monitor mysql, I get an error that reads "Running configuration check... CONFIG ERROR! Restart aborted. Check your Nagios configuration."
define service{
use local-service
host_name localhost
service_description MYSQL

This is pretty much what I added to monitor other things on the server such as ftp and smtp, just switched out check_smtp with check_mysql, etc.
Is there a reason why the selinux module for nagios just doesn't work? I'm running CentOS release 5.4 (Final) and did "yum install nagios" and now have nagios-3.2.0-1.el5.rf installed. I'm having to create policy after policy after policy, and still haven't reached the end of the rainbow.
I suppose after I run out of selinux violations, I could figure out how to combine all of these modules and post the result, but it seems really, really weird to think that I'm the only person who has ever installed nagios from the repo with SELinux enabled.
I know that I can use the GUI (gnome-volume-properties) enable/disable the USB sticks/disks automount features, by checking/unchecking the pertinent options.My question is: how can I obtain the same results from the command line (that is, without using any GUI frontend)?
View 5 Replies View RelatedWe have Nagios running on a server, and are installing NRPE as a daemon on web servers we need to monitor. I'm two servers in and have hit a small snag. The two servers we're currently trying to monitor are, to the best of our knowledge, very similar (Centos 5.4, Apache, MySQL, PHP etc etc), and the installations of NRPE on them should be the same. One is being monitored just fine, however we can't check on the other one without including the -n switch (to disable SSL) in the check_nrpe call. If we don't, however, the error we get is, "CHECK_NRPE: Socket timeout after 10 seconds.". In /var/log/messages on the machine that fails we see:
May 24 17:23:49 ourserver xinetd[23583]: START: nrpe pid=27932 from=123.123.123.123
May 24 17:23:59 ourserver nrpe[27932]: Could not read request from client, bailing out...
May 24 17:23:59 ourserver xinetd[23583]: EXIT: nrpe status=0 pid=27932 duration=10(sec)
The only kind of related thing I can think of that's different between the two machines is that one (the one that works) has actually had an SSL certificate installed on it, for the site it hosts.
I'm trying to setup my test nagios to check the disk space of another linux box. I've got it setup and checking. But to my surprise, it was checking the nagios server's local disk space instead of the remote linux.

I'm trying to figure out how to operate a rather large Java program, 'prog'. If I go to its /bin/ dir and configure its setenv.sh and prog.sh to use local directories and my current user account. Then I try to run it via "./prog.sh start". Here are all the relevant bits of prog.sh:
[code]...
When I actually do ./prog.sh start, it starts. But I can't find it at all on the process list. Nor can I kill it manually, using the same command the shell script uses. But I can tell it's running, because if I do ./prog.sh stop, it stops (and some temporary files elsewhere clean themselves out).
[code]...
the process is running yet not in any way listed by the system. I can't find it in ps or /proc/, nor can I kill it. But the shell script can still stop it properly. So my question is, how can something like this happen? Is the process supremely hidden, actually unlisted, or am I just missing it in some fashion? I'm trying to figure out what makes this program tick.
