Hi @hose93
are there any plugins or localchecks running on that host?
Please check under:
/usr/lib/check_mk_agent/plugins/
/usr/lib/check_mk_agent/local/
If yes please remove the execution permission to test if the long runtime is caused by one of your plugins. (e.g. sudo chmod -x pluginname)
Then check the execution time again to find the cause of the long execution time.
Regards
Norm
