Tweaking centreon

Hi,

I have for a couple months now had issues mainly with the hosts and ICMP. Hosts are pinged every minute to get the UP/DOWN status. I’ve noticed that every other ping is basically failing in a “CRITICAL”. I have tried manually to ping some of these hosts from the same server and there are no network related issues.

The issues seem to mainly be related to performance. For services UP/DOWN these checks work better but they are scanned every 5 minutes.

Occassionally there can be a PROCESS TIMEOUT. 

I’m running centreon 24.10.25 on Debian 12 with 4 vCPU and 16 GB memory.

We have 478 hosts in our centreon environment and 2052 services. This is running on one cenral poller.

I’m thinking about setting up one more poller to see if it might solve things.

The “tuning” tab on the engine configuration looks like this.

I wonder if the underlying engine has issues running your ping commands as they are run by the same local user.

I had some issues when using lots and lots of ping services on the same poller What if your services regularly fail in batch out of nowhere ? | Community

Maybe on your end if you lower the amount of concurent commands, but you will probably end up with some check latency.

The solution to use some other dedicated poller could be the solution if this is the issue you are facing.

Hope you can figure it out 🙏
