Nagios Support Forum

Greetings,
I have a server with several virtual interfaces. Each interface is tied to an apache instance. If I want to monitor them with nagios, would I have to create a check_http command for each individual interface? Also, this is being performed by check_nrpe
i.e.
command[check_http].....
command[check_http_vnic1]...
command[check_http_vnic2]...
etc...
I am only interested that apache is running and responding but don't want to do a website check as the front end is load balanced and could either go to two different servers. So I need to ensure that I am checking on each server that the service is running.

Any advice on the best way to accomplish this is appreciated. Thanks in advance.,

Jeff

You'll have to use NRPE for sure with check_procs and use the -C flag which will cause check_procs to look for processes started using the EXACT -C arguments, so to test to see if Nagios was started with the config in /etc/nagios.cfg rather than /usr/local/nagios/etc/nagios.cfg we would enter

check_procs -C 'nagios -c /etc/nagios.cfg'

I have to monitoring process ora_pmon_sinamp. The process is running in the machine (HPUX):

oracle 28067 1 0 02:48:37 ? 0:03 ora_pmon_sinamp


but, when I executed command:

/opt/iexpress/nagios/libexec/check_procs -C 'ora_pmon_sinamp'
PROCS OK: 0 processes with command name 'ora_pmon_sinamp'

How I can monitoring this process?

Regards.

Are you executing this command from the same machine as the process in running?

Type in terminal (on the target machine):
to make sure the process is running.

Next, edit your "check_local_procs" command definition in the "commands.cfg" file:
Change it from: "$USER1$/check_procs -w $ARG1$ -c $ARG2$ -s $ARG3$" to "$USER1$/check_procs -w $ARG1$ -c $ARG2$ -a $ARG3$"

Check if you can monitor this process locally:
If you succeed, you can type in terminal (on your Nagios server):
You can also add arguments for warning and critical, for example:
Once you make it work from the command line, you can deal with the web interface. This document may help you with this:

I probed this, but appear process is down. I see that in HPUX, not correctly ps:

When I do ps -el:

1401 S 30208 1023 1 0 154 20 e0040100009c4380 25741 e00000019b2292e8 ? 0:02 oracle

If i do export UNIX95=1

1401 S 30208 11276 1 0 154 20 e000000198924c80 25689 e000000144cee080 ? 00:00:00 ora_pmon_sinamp

but if i do:

command[check_procs_pmon_sinamp]=export UNIX95=1;/opt/iexpress/nagios/libexec/check_procs -C ora_pmon_sinamp
PROCS OK: 0 processes with command name 'ora_pmon_sinamp'


If I defined in nrpe.cfg:
export UNIX95=1
command[check_procs_pmon_sinamp]=/opt/iexpress/nagios/libexec/check_procs -C ora_pmon_sinamp

Appear this:

PROCS OK: 0 processes with command name 'ora_pmon_sinamp'

Any idea?

Try this command:
or Let me know if this works.

I probed this but is not correctly:

/opt/iexpress/nagios/libexec/check_procs -C ora_pmon_sinamp
PROCS OK: 0 processes with command name 'ora_pmon_sinamp'

UNIX95=1 /opt/iexpress/nagios/libexec/check_procs -C ora_pmon_sinamp
PROCS OK: 0 processes with command name 'ora_pmon_sinamp'

Any idea?

Regards.

Excuse me, I was wrong when he wrote.I probed two options:

UNIX95= /opt/iexpress/nagios/libexec/check_procs -C ora_pmon_sinamp
UNIX95=1 /opt/iexpress/nagios/libexec/check_procs -C ora_pmon_sinamp

And the output:

PROCS OK: 0 processes with command name 'ora_pmon_sinamp'

I add too in nrpe.cfg, but the output is the same.


Thanks,

Is this process running? Can you run a test against a different process, that is running for sure?
