Troubleshooting

CMK version:
2.2.0p25.cce

OS version:
Ubuntu 22.04.4 LTS

Error message:
Custom check mk agent plugin is not discovered

I have custom plugins on my remote host:

ls -lR /usr/lib/check_mk_agent/plugins/
/usr/lib/check_mk_agent/plugins/:
total 38
drwxr-xr-x 2 root root     4 Apr 26 15:13 3600

/usr/lib/check_mk_agent/plugins/3600:

-rwxr-xr-x 1 root root 108 Apr 26 14:46 borgmatic_archive_stats.sh
-rwxr-xr-x 1 root root 108 Apr 26 14:46 borgmatic_backups_stats.sh

and i have two issues:

  1. plugins under plugins/3600 folder are not discovered
  2. nginx_status.py plugin workd well, but when i added plugins in 3600 folder, it is also missing in Service discovery

plugins working well, here are outputs:

root@vps:/usr/lib/check_mk_agent/plugins# ./nginx_status.py

0 "Borgmatic[backups]" num_of_files=7433|duration=56.0 Borgmatic backup status of backups

have somebody any advice, why 3600 plugins are not discovered and why nginx_status.py plugin disappeared?

I cannot edit my post, but I forgot to write, that all other custom agents are working well

the plugins folders is not meant for normal local checks, it expects if I recall correctly the output as you have in nginx status.

You should have regular checks in “local”

ok, moved to local, and it started working, thanks :+1:

my icecast* checks return same format and is working well in plugin folder, so probably problem was that 3600 subfolder

the plugins folder dont support cached local check iirc.
you can convert them to a real plugin perhaps.

thanks, but probably I am ok with that in local folder because documentation about custom plugins is somewhat too long Writing agent-based check plug-ins

is there some benefits to have plugin instead local check?
