Hosts and Services display 0 servers in GUI

I’ve imported centreon and centreon_storage from my RHEL7  server to a new RHEL8 server  configured with  Centreon 21.04. 


  - the GUI does not display any HOSTS or SERVICES = “0” but my poller is running

  - if I export the poller  (Move/Restart/Post), The Console displays the progress  at 0%.


Any ideas where I should look to fix this?

Hello @jcarrier

You just use a new server with a new OS RHEL8 and you install a 21.04 with the dump of the older platform only ?

You don't do any change on your Pollers (OS, Centreon Version) pollers are on 21.04.x supported by your 21.04.x you installed on your Central ( ?

You use Gorgone for the connection between your Central and your Poller(s) or SSH ?

Maybe, you just do redeploy your gorgone configuration because you change the Central ? (a new thumbprint with the new central)

When you solved the communication problem, i think you do upgrade your platform to a supported version

I don't understand your last post versus the first.

For the first have you follow this guidelines :

Most particulary the last indication with the replacement of IP adresse ?

Could you share some logs of gorgone /var/log/centreon-gorgone on Central and Poller(s) and also /var/log/centreon-engine
