Nagios Support Forum

Hello,

I want to monitor different java/ ssh etc processes on ubuntu with nagios xi.

kindly assist.

Thank you!

Without knowing more specifically what it is you care to monitor, the following articles are likely a good starting point:

I want to monitor java process running on web server and mysql process on db server.

Is using an agent like NRPE or NCPA an option? Were you looking for an agentless solution?

Any kind of solution!

agentless or with agent

One of the documents provided by @tmcdonald provides some steps for setting up the NRPE agent:

We also have a trouble shooting document that might be useful if you run into problems:

Once you have NRPE installed and listening on the remote machine, you could use the check_procs command to make sure the Java process is running like so:
Since Java is not running on my remote machine, a "critical" state is returned.

[root@AXmonitor libexec]# ./check_nrpe -H 1.2.3.4 -c check_procs -a "-c 1: -C java"
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.
[root@AXmonitor libexec]#

I have troubleshoot alot from internet and found that dont_blame_nrpe=1 and restart nrpe service.

I have installed the nrpe agent by using following how-to

http://tecadmin.net/install-nrpe-on-ubuntu/#

Operating system= Ubuntu

I would suggest following our official documentation for installing NRPE:
https://assets.nagios.com/downloads/nag ... _Agent.pdf

I would also suggest resolving the specific NRPE issues you are experiencing in your other thread first:
https://support.nagios.com/forum/viewto ... 991#194165

Otherwise it will be difficult to check a specific process with NRPE when it is non-functional

All my monitoring is fine with nrpe, but still I am unable to monitor java process with given command.

[root@AXmonitor libexec]# ./check_nrpe -H 1.2.3.4 -p 5666 -c check_procs -a '-c 1: -C java'
CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.

Kindly assist.

Thank you!

Verify that the command is setup in the nrpe.cfg or common.cfg file on the remote system is setup and that the arguments are defined correctly for that command.
