We having an issue with one of our poller. to give you some details of our monitoring infrastructure, its composed of 1 central server with 2 poller on our clients’s site.
They are all in the same version 21.10:
The most part of time the poller work correctly and do his checking / notification job. But when we lose the whole part of client infrastructure (~70 hosts and ~300 services) the poller doesnt send the notification on time, also the scheduling part seems to have some problem some host are lock in soft state :
Also as you can see in the first screenshot the UI shows that the poller have some latency
For the notification part we receive 2 mail every minutes , so sometimes we receive the mail for one check one hour after the check changed his state.
I checked the centengine.log and i found some interesting things :
But i didnt found any interesting topics on the web.
We also tried to reinstall the poller … but it didnt solve the problem.
The other poller is working correctly, we tried a notification test and he acted normaly.
Does some of you have meet this problem ?
Thx in advance
