Ghost hosts in nex UI after poller loss

Hello everyone,

Version information :

Centreon version 22.10.2

PHP 8.1.13

Last week, half of my vms died from storage failure. I monitor my vms using one central instance, and two pollers, poller1 and poller2.

When the poller 2 died, I made a mistake, and tried to delete the poller and all the hosts linked to it in the Web UI, causing a lot of issues with ghost hosts.
I’ve followed web tutorials explaining how to remove them from the centreon_storage database, in the HOSTS table.
I thought this solved the issue, but it did only in the deprecated view. In the new view, the old hosts still appear, and when clicked on, make this popup appear :
 

 

I’ve looked into the various logs and found nothing except for this log :
CRITICAL: Host 2048 not found {"context":"[object] (Centreon\\Domain\\Exception\\EntityNotFoundException(code: 0): Host 2048 not found at /usr/share/centreon/src/Centreon/Application/Controller/Monitoring/MetricController.php:82)"}

I’ve tried to restart php and the web server to no avail, i’m guessing this may be a cache issue more than a sql issue, because the old view works fine and doesn’t display the old hosts anymore.

If you guys have any idea, i’d be glad to hear them,

Thanks

Hello, 

The new view use the centreon_storage.resources table containing services, meta-services hosts and, business activities. You will have to remove them from that table too.
