I notice that the check process of my Centreon-engine (22.04.0) of my central server is broken from time to time, without disturbing my supervision.

I think, i have no problem with my RAM:

>root@Central]# free -m
              total        used        free      shared  buff/cache   available
Mem:          23889        5178       17146          40        1564       18293
Swap:             0           0           0

 

I check ~ 6 000 services and 300 hosts

Have you seen this problem before ?

Thank you

 

@Cyril_31 

do you use reload or restart on the export?

I use restart on the export.

What setting do you have for the memory? maybe too low?

 A restart maybe showing as process down?

The memory check for my centreon server is:

Warning: 80%

Critical: 90%,

but i have no error on this check.

It’s only centreon-engine that i have the error

 

Is it possible to active “debug mode” for centreon-engine ?

Because on the /var/log/centreon-engine/centengine.log, i only see if the centengine service is up or down, but not previous events, like errors for example.

Thank you

You can select your logs under:

Configuration  >  Pollers  >  Engine configuration

for the poller in question.

 

If you time the restart?

`time systemctl restart centengine`

 

You can also use reload instead, less heavy
