use client_data/catalog/<fqdn>.json for nagios check?

[Bernard Clark]

We need to be alerted whenever a puppet report from any puppet client is late. We were thinking of having Nagios monitor the last modification time of a client's /var/lib/puppet/client_data/catalog/<fqdn>.json and alert us when that file ages too much. Anyone have a better idea?

I use a script that checks if the puppet client is running and parses the lastrunreport for last run time and if any errors were reported applying the catalog.

This one from RIP works ok for me:

I've used two different ways of doing this, depending on whether or not you have this stuff installed/running:

(1) if you have PuppetDB, just use that. I probably have a (Python) check plugin for this somewhere if you need it.

(2) use `mco puppet status` and parse the output of that

These also have the advantage that they can be run as cron'ed passive checks, and submit the results very efficiently.

We use this one : https://github.com/liquidat/nagios-icinga-checks/blob/master/check_puppetagent

But you have to modify it if you are using an earlier version of Python for the date time code to get the difference.

It's also good if you check the report file for errors. Rather than just the summary. We check both.
