Today I saw, that our check_mk stopped working to collect or to show the graphs since 14. Oct. There’s a cut until today. Also I have some issues with some check which checked at least at the same date and time (14.10.19 - 15:00:02). I can’t determine what’s happened at this time. Any ideas how I can get it?
Check_MK version is 1.5.0p22 with Debian 9.
Installed a fresh new Linux system with check_mk and restored the backup. And even in the fresh new installed system (with the old backup) the pnp4nagios/rrd graphs are not working.
Is there any possibility to the somewhere in the system what went wrong?
The check interval is 60/60 but " The time of the next scheduled service check 15 m in the past!"
