Prerequisites
IMPORTANT: The poller is a component that is deployed in the customers' infrastructure. Its administration (material and virtual infrastructure, OS, security, monitoring and Centreon applicative layers, etc) is solely the responsibility of the customers, as per the Terms and Conditions.
Deploying a poller
With Centreon Cloud, your central server is already ready to use. All you have to do is to install pollers in your infrastructure, and that is very easy: just execute a script and then export the configuration, and there you are!
Updating/upgrading a poller
IMPORTANT: It is the customer's resonsibility to update the OS of the poller's host machine. Also, Centreon provides application updates for pollers, but it is the customer’s responsibility to apply these updates to their pollers.
Securing your pollers
IMPORTANT: It is the customer's responsibility to secure the OS of the poller's host machine, and to update its OS.
Monitoring your pollers
The best practice is to have a poller monitor another poller (i.e. no poller should be monitored by itself).
Troubleshooting your pollers
This document provides procedures to troubleshoot issues with the Centreon pollers in the Centreon Cloud environment.
Migrating a poller to another host machine
In some cases you might want to change the OS of the host machine for your poller. The correct procedure for this is to install a new server and migrate your resources to it.
Removing a poller from your architecture
In order to ensure the stability and integrity of your monitoring environment, do not delete the central poller. The central poller plays a critical role in the overall operation of the Centreon platform. Removing it can lead to unintended disruptions in service. We are in the process of implementing safeguards to prevent the accidental deletion of the central poller.
