I test it again …
… adding slowly monitored hosts to the pmm server.
After doing this for the first 9 server only 3 minutes after adding number 10 the monitoring stopped completely.
Again there are no log entries in /var/log/prometheus.log and ALL metrics on ALL servers are in running state, but without connectivity to the server:
SERVICE TYPE NAME REMOTE ENDPOINT STATUS
-------------- ------- ---------------------- -------
linux:metrics db-1-2 x.x.x.x:42000 DOWN
mysql:metrics db-1-2 x.x.x.x:42002 DOWN
PMM is a nice and helpfull tool, but it seems not very robust and we are not able to work with it at the moment.
What can I do?
