Hi !

I’m not an expert but maybe I can help.

I think I had this issue but with Nagvis.

I believe you already exported the configuration like so :

If you haven’t already, try restarting centreon

sudo systemctl restart centreon

Tell me if the problem still persists, I think there’s a folder on your central server you can clear. I just don’t remember which one.

Cheers

Cleaing the cache freezed the app, restart poller and centreon do not help.

Is it not working anymore ? I deleted that part in my message after I wrote it as I do not fully understand it’s effect.

if not, try restarting apache and then centreon

Can you send the output of these commands ?

systemctl status gorgoned

systemctl status centengine

ls -l /etc/centreon-engine

It was restored from backup.

Alright, permissions seem correct here, there are some pretty old files in there, what version of Centreon are you using ?

And if you

nano /etc/centreon-engine/hosts.cfg

or

vi /etc/centreon-engine/hosts.cfg

Do you see these deleted hosts ?

nano /etc/centreon-engine/hosts.cfg

or

vi /etc/centreon-engine/hosts.cfg

No, poller that monitored these hosts doesn’t exist yet.

PROBLEM SOLVED
Deleted hosts in SQL from table hosts in centreon_storage DB.
