Just trying out LibreNMS to replace our current observium, we also use Check_MK.
I installed the check_mk agent from LibreNMS to try and get better MySQL stats.
and the server I was monitoring (CentOS 6.8 LAMP) started giving all sorts of
alerts in Check_MK, is there a big diffrence between the LibreNMS agent and
the OMD Check_MK Agent?
OMD Check_MK Agent is version 1.2.6p12
LibreNMS is d526a16 on Cent OS 7
It seems I missed a few server agents when I upgraded my OMD install,
Check_MK agent version 1.2.4p5 seems to be incompatible with LibreNMS,
all seems OK until you try to add the Unix Agent and any Application
Had a quick look at the files and there are quite a few changes in the code,
and extra 20 lines of code in 1.2.6p12.
