Nagios XI 5R1.0 JMX Not Working

[kvaldez]

Hi guys,

I have configured the check_jmx plugin for Nagios XI 5R1.0 and im getting this error on the NagiosXI service configuration -> Test Check Command.

Test_Command.jpg

Code: Select all

OUTPUT: JMX CRITICAL - java not found

This is very weird because on a terminal I get a positive output and everything seems to work fine.

Im posting the respective pics so anyone can help me.

This is the check_jmx script:

Code: Select all

#!/bin/sh
#
# Nagios JMX plugin.
#

JAVA_CMD=`which java`

if [ -z $JAVA_CMD ]
then

  if [ -x $JAVA_HOME/bin/java ]
  then
    JAVA_CMD=$JAVA_HOME/bin/java
  else
    echo JMX CRITICAL - java not found.
    exit 2
  fi

fi

DIR=`dirname $0`
$JAVA_CMD -jar $DIR/check_jmx.jar "$@"

Thanks in advance!

First thing to point out here would be that the test check command is VERY buggy. I would not use it, as it has issues with special characters. What is the error on the service detail screen?

I dont get any error on service detail screen.

But when going to Home -> Service Detail Screen on Nagios XI I can see this:

Can you try to run the check command from the command line as the 'nagios' user?

Hi,

Thanks for your reply.

From command line this is what I got:

But what do you mean for run as 'nagios' user?

If you run the command from the command line as root, it sounds like the check is working.

What happens if you switch user to 'nagios' and then run the same check command?

su nagios

Hi,

This is the output from running the command as nagios user:

I am not sure if it is going to be this simple, but upon looking at your stuff closer, in the first screenshot you are checking 192.168.0.100... in the command line check, you are checking 192.168.0.99.

Yep, I was trying to connect to different hosts but I always get the same answer, even if the host doesn't exist Im getting the same error:

Code: Select all

OUTPUT: JMX CRITICAL - java not found.

In your command definition, can you try wrapping the '$ARG' commands in single quotes, or at least the ones that are going to have a space or symbol in them?
