I have a question. This weekend I lost information about PING on several devices being monitred on Checkmk for 3 days. I do not know what could have happened. These are the graphs that show this gaps this weekend. At some points it shows info but then lost info again. Do you know what or where I can find information about this? I mean logs or something else.
It is important to mention that only the PING failed and caused the down, but the other services were getting info
We have checked some logs, however, nothing related to the gap we can see in the graphs.
One question - is this graph the host ping or an normal ping check configured?
If it the host check it can be that the host check for these hosts was disabled at the time without graph.
The deactivation of the host checks you will find inside the core log as external command.
