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?

The maintainers of this plugin have a gitter chat which seem...

Never heard of Nagstamon before this post, but try this:

The upgrade script used to upgrade Nagios XI includes multiple considerations for updates to NRPE, nagios-plugins, ndoutils, and Nagios Core. $ cat upgrade | grep NRPE NRPE_UPDATED=0 # Upgrade NRPE to latest if [ $NRPE_UPDATED -eq 0 ]; then NRPE_UPDATED=1 $ cat upgrade | grep NDO NDO_UPDATED=0 # Mod...

Which version of NSClient++ are you using?
