Hi !

I have a question, Im doing a Centreon HA. But there is not HA with the pollers or the remote servers right ? So even if we have Centreon central HA with a master and slave but our pollers or remote servers goes down we have no more monitoring because they collect all of the data. So Centreon HA is not really HA then, how we can do poller or remote server HA ? To be sure that everything is HA ?

 

Thanks for your answers !

If someone have the answer, it can help a lot of people. Because if a poller goes down even if you have two Centreon Central HA you can’t do nothing because everything is collected by the poller remotely, normally with Centreon HA you don’t use centreon central as a poller it is says in the documentation centreon HA. Its only the poller added on  centreon central that collecte data.

“In the case of a highly available architecture the Centreon central cluster must not be used as a poller. In other words, it should not monitor resources. Its monitoring ability should only be used to monitor its pollers. If this recommendation is not followed, the centengine service would take too long to restart and it may cause the functional centreon group to failover.”

From the link(I already knew it)

Thats why Im asking it, if we can’t use Centreon Central as a poller, but if we add other poller to the collect data. It complicated when the pollers goes down because then we will have nothing to collect data. You see what I mean ? But if you know how to solve this problem in a certain way im open to anything

Thanks for posting an idea on that topic:

 

Whilst there might be ways to trick the set up to get some failover capability on the pollers, there is no comprehensive method. Best we can do is to continue our effort on poller resiliency by, improving the architecture (e.g. to support clustered and/or containerized collect systems).

Hello ! What is the trick that you know to get some failover capability that I can test please ? I really need it
