i’m new in monitoring with ceck_mk. For the Last Years i used icinga and icinga2.
Because of an article in c’t i decided to try check_mk
It seems to work but i have a Requirement to add custom notes for Hosts. For example the Serial Number of a Device or a Phone Contact Number.
I found this tutorial but i think it is obsolete https://mathias-kettner.de/checkmk_multisite_notes.html
I have no folder /etc/check_mk/ mine is running under opt/omd/sites
How can i add Custom Notes?
