Hi there, this plugin is really useful, thanks!
We have been using the 2018 version for some time which works well. When we upgrade our sites to the 2024 version the health check returns an HTTP 303. Any clues as to why this might be? We are a bit stumped at the moment.

It would be nice to have official support for MDL 3.5 (and up)
How about caching checks? Redis support needed.

hi Benoît,

Yes the testing mode is only for the croncheck, and yes the session check is hard coded and quite hacky (we don't actually use that particular feature very much, it's monitored in other ways). It would be much better if it detected which session handler was being used and each session handler declared it's own concept of healthy which is the intention of this tracker which ideally will make this plugin redundant:

...
and the 'tool_heartbeat | testing' setting is only applied for the 'croncheck' script, right?

Best regards,
Benoit.

Hello,
Context : Moodle 3.2/LAMP
This plugin seems to use the 'memcache' PHP module, not the 'memcached' one, to check Memcached session server (if apply). Correct?

Thanks for you great job!
Best regards.

If you are not familiar with configuring nagios using the cli plugins, it might be easier to configure nagios to test whether any arbitrary url is working and then point it at the heartbeat url which returns a 200 or a 503

Good morning Brendan

I just discovered this simple tool to check the status of any Moodle platform. I was interested enough because in our organization, we manage several platforms Moodle and our Nagios is difficult to check whether the site is ok or not, if the database connected or not connected.

I tested it in a test environment and the truth is quite functional and very useful. What interest me is how to include the two checks (the fullcheck and croncheck) in the Nagios service we have assembled in our company.

Anyway thank you very much.

Hi There

This looks a brilliant tool - I have been wanting to have some sort of error tracking on the cron for a while!

Can you tell me how to integrate it into Nagios?

Thanks
John Rickard

hi David, re #1 that is now automated in code with no config needed, I'll add a new version here. Thanks

Thanks Brendan for sharing this plugin. It is apparently focused on sites with quite specific setup. I found it working as expected. The only suggestion I have was reported to your issues tracker. With the hope that will be fixed soon (I can imagine info in the README and in the plugin description here), I am going to approve this now. You are cleared to land, welcome to the Plugins directory!
