Hi all,

I have a patch in flight at the moment [0] to install check_mk server and compliment the already merged installation of check_mk agent [1] so my thoughts are now turning to how we would recommend adding new service checks.

The concept behind check_mk makes this really simple to do.  You just place a script that outputs "<status_code> <check_name> <performance_data> <message>" into the agent's "local" directory (/usr/lib/check_mk_agent/local on Ubuntu for example) and it will be picked up the next time an inventory of the system is run.

There are two ways that we can recommend doing this:

1) We ask users to update the check_mk_agent T-I-E every time they wish to add a new check
2) We ask users to distribute checks from their own T-I-E into the correct location

In my opinion, requiring an update to check_mk_agent for every new check is the wrong way of doing this as it means that all systems get all checks regardless of function.  Far more preferable would be option 2, however I'm open to other ideas, especially if they mean that organisations using this don't have to go through the review process if they have checks they wish to keep "behind the firewall" for IP/Licensing reasons.

Thanks in advance for any help people can give on this,

Matt
