Nagios Support Forum

You can add it to the nsclient.ini and/or see if nsclient has an internal service check.

Check the status output for the service and the logs.

In the meantime you may want to set a cron to restart logstash.
In my experience logstash was pretty reliable BTW.

Check the status from the shell after starting via the web page.
A guess is that the web user has to sudo to start the service and it's disabled.

Silly question but what about IP addresses do you want to manage?

How to set it up is in Dell's documentation. You just set the nagios hosts as a destination, etc. You can probably figure it out w/o docs.

There's no livestatus log?

What does the livestatus log say?

It isn't producing any perfdata so no graph. Try the -h option to see if it has an option to make perfdata. If not you need to modify the script or find a new one.

Perfdata comes after the | char at the end of the plugin output. Is it there if you run the script manually? You may want to post the output.
