Hi

We are unable to get Apache monitoring over NCPA to work:
"UNKNOWN: Error occurred while running the plugin. Use the verbose flag for more details."

We had follwed the manual aside from the unclear NCPA config change after check_jvm.jar is installed (should there be any changes)
Also, we have Oracle JDK we are using, but not the Open JDK. Would it be a must to get both of them installed?

Thank you

Can you run the check from the command line and add a -v to it? That will give you the verbose output, and should give us a better idea of what is going on.

Where would I add -v ?

-t alfresco -P 5693 -M plugins/check_jvm.jar -q "args=-s service:jmx:rmi://ignored/jndi/rmi://10.102.75.70:50500/alfresco/jmxrmi,args=-u 'monitorRole ',args=-p 'SuperCraneInKCForQAECM2018',args=-t tomcat,args=-C 'MemorySimpleHeap,MemoryOld,MemoryMetaspace,ProcessCPUUsage,SystemCPUUsage,ThreadCount',args=-w '7516192768,5368709120,314572800,75,80,225',args=-c '8589934592,6442450944,419430400,85,90,250'"

Putting the -v right after the port like this should be fine.

Here is the output

Connecting to: https://10.102.75.70:5693/api/plugins/c ... InKCForQAE
An error occurred:

That's odd. I don't see 'reason' specified anywhere in that command. Does this plugin work if you run it directly on the host with the same command line switches?

what would be the full command?

I'm not quite up on how to run Java files. But that does bring up another point. We should check your ncpa.cfg file to make sure that there's a Java handler. Can you post your ncpa.cfg file?
