[Check_mk (english)] thresholds for custom checks

Archive checkmk-en
1

I’ve written a custom check for Linux updates that lets you set a warning and critical threshold for either/both regular updates and security updates (ie., >= 1 security update is critical whereas we let other updates go to 10 or more).

I see on this page:
https://mathias-kettner.de/checkmk_localchecks.html at the bottom under limitations it says: “WARNING and CRITICAL levels have to be configured and handled on the host itself.” Am I understanding that correctly that that means I cannot define these thresholds
via rules ? Is that something that will change in the future?

Thanks,

Lance Tost

Actually, a plugin is what I wrote. I guess I got the terminology mixed up. You can find it here: http://exchange.check-mk.org/index.php?option=com_remository&Itemid=59&func=fileinfo&id=153

It has a shell script to put in the agent’s plugins directory that outputs like this:

<<<linux_updates>>>

0 0 2 0

log4cpp.x86_64 1.0-13.el6_5.1 updates, nfs-utils-lib.x86_64 1.1.5-6.el6_5 updates

First row: Reboot_required (1=yes), missing_statusfile (1=yes), num_updates, num_securityupdates

Second row: List of all updates

And then a python script in ~/local/share/check_mk/checks that has this set at the top:

thresholds: updateswarn, updatescrit, secupdateswarn, secupdatescrit

linux_updates_defaults_params = (10, 75, 1, 1)

But I’m looking for a way to set those parameters above via the gui. When I look at the service in wato, there is no “check parameters” icon next to it.

The first column in the output of a local check is the status (0,1,2 for OK,WARNING, CRITICAL) so the check must know
the thresholds in order to determine the status, so I know of no way to use rules on the monitoring server side for local checks.

You could write a plugin, then configure the server side to process the plugin output, but that’s more complicated.

It is possible to add WATO configuration for own plugins but it is not so easy for the first try.

If i want to write a small check what is running as a script from the agent then i take the local check with automatic calculation of return code.

It is descripted here - https://mathias-kettner.de/checkmk_localchecks.html - on the bottom under “local: New state type P for state computation based on perfdata” this is very nice for small scripts to return a valid check without any configuration inside check_mk system.

Disadvantage - you must configure the tresholds on the agent side.

I ran across this a while back:

http://lists.mathias-kettner.de/pipermail/checkmk-en/2013-February/008626.html

but I haven’t had time to follow up on it. Maybe there has been improvements in

later versions to allow adding plugin configuration to WATO.
