(If it is a problem with checks or plugins)

Good Day @all =),

since yesterday i try to setup my first “local check” (Found file log4j?)but it is not working…

I set up everything like in the topic i have linked above.

In checkmk itself for the host iam not getting this service.

From the Error analysis i get this information:

“5.2. Testing agent output on the target host”:
No Result, only a blank line.

“5.3. Testing agent output on the Checkmk server”:

Error in check include file /omd/sites/XXX/local/share/check_mk/checks/temperature.include: [Errno 2] No such file or directory: '/omd/sites/XXX/local/share/check_mk/checks/temperature.include'

I used the search of the forum und tried some ideas and solutions from there but without success. Maybe someone else have an idea oder the solution for my problem.

Hi CheckmkRG

To avoid misunderstandings: A local check is a (simple) check script that is run directly on a monitored host. Checkmk uses its output as-is and does not itself do any checking. This is what the documentation you linked describes: Local checks

As such, the FileNotFoundError you are encountering above will not be caused by a local check. Rather it could be caused by some pre checkmk 2.0 plugin that is still installed on your checkmk site.

This means, you will most likely be facing two unrelated issues here.

To (hopefully) guide you in the right direction, I have the following questions:

What check for log4j are you actually using? Did you install the MKP provided by @thl-cmk on Checkmk Exchange?
What OS does the host run you are trying to monitor with this log4j plugin?
Are there any checks inside the folder local/share/check_mk/checks and if so, does any of these files mention temperature.include or humidity.include?

Kind regards

As addition to the hints from @ttrafelet i would said that the file not found is something that happens after the upgrade to 2.0 if you had before some checks installed inside local/share/check_mk/checks. But this message als stays after you removed the old plugins. The cause for this is that CMK caches the precompiled checks inside the following folders.
~/tmp/check_mk/check_includes/local
and
~/var/check_mk/precompiled_checks/local
If you cleanup booth folders and get again the error message then there must be some old plugins inside local/share/check_mk/checks who try to use these files.
Here inside this Werk you find the description what needs to be done with old plugins and includes.
