The centreon poller does not run after exporting the configuration

Question

I want to connect my poller to start monitoring. Unfortunately when exporting the configuration, the poller does not start running

View no executed poller (NON)

I tried to change the IP of the poller, restart the gorgon services of the two machines, nothing worked.

Anyone have an idea of ​​the solution?

Answer 1

One common oversight on fresh installs is to not disable the firewall and the selinux. From personal experience, it may help to restart all processes in the command line after the first config export attempt from the web interface (Configuration > Pollers > Export Configurations).

On pollers:

systemctl enable centreon centengine

On Central:

systemctl restart php-fpm httpd24-httpd centreon cbd centengine gorgoned

Otherwise, I might need more information. If your issue hasn't been resolved yet, mind sharing:

• Your centreon version (from the capture I'd guess Centreon 22.04)
• You install medium (from source, packages, OVA/VM)
• Your distro

You may find some more clues in the logs:
