Nagios Support Forum

Dear Team,
I am trying to configure nagios monitroring for one of my java application and when i try to run the check_jmx plugin from the nagios server i am getting the below error.
Kindly let me know if i am missing anything here.Please find the command which i am executing from the nagios server.

I have copied the check_jmx and jmxquery.jar in the path /usr/local/nagios/libexec

./check_jmx -U service:jmx:rmi:///jndi/rmi://x.x.x.x:8686/jmxrmi -O com.itac.management:type=Servers,host=*,process=* -A UsedHeapSize -w 18000000000 -c 20000000000 -p B -username xxxx-password xxxx

regards,
RKJ

Can you show us the specific error your are getting? A copy+paste of the command executed and it's corresponding output would be useful.

Can you also describe how JMX is configured in the remote application you are trying to monitor?

Thanks @mcapra!

Did you mean to attach a screenshot or is that just a typo regarding the error?

Also, please see @mcapra's question above.

@dwhitefield yes it was a a typo. i have pasted the error logs in the previous reply.
@mcapara i will check with application team on the same and update you the status.

Regards,

RKJ

It's worth mentioning that if you're using the Glassfish JMX server rather than Java's native RMI, you may need to do some tinkering within the jmxquery.jar package. I don't have a Glassfish server to test against unfortunately; Perhaps I'll add one to my lab environment.

Can you also share where you got check_jmx from? There's many different iterations of that plugin from different maintainers.

Thanks for the assist, @mcapra! OP, let us know if you need further assistance.
