Symptom

In the Configuration > Pollers menu, the servers corresponding to the remote server and the attached pollers are set to No in the Is running? column.

Solution

Some Centreon processes must be started in a specific order. Indeed, the cbd process of the remote server must be started before the centengine processes of each poller (including the remote server itself).

• Restart the cbd process on the remote server:

# systemctl restart cbd

• Restart the scheduler on each poller (including the remote server itself):

# systemctl restart centengine

• Go back to the Configuration > Pollers menu, now the servers should be set to Yes in the Is running? column.
