Hello,

We have a pool of servers that respond to charge and some of them can be shutdown or started in consequence.

I don’t know how to manage this in Centreon.

We have all the hosts configured in it, with disk space usage/CPU/RAM/Ping service monitoring through NRPE (NSClient++) + the notifications in case of WARNING/CRITICAL but when the host goes down the notifications are sent but we want to avoid this.

Do somebody have already face this kind of need?

Thanks for your reply!

What technology do you use for this? Is this in the cloud (e.g. autoscaling group in AWS) or on-premise (e.g. using OpenStack)?

Hello @rchauvel,

The servers are hosted in Azure

Hi @l.malherbe, 

Sorry if my answer seems naïve but what about disabling notifications for these hosts and making sure that in Configuration > Pollers > Engine configuration under the Check Options tab, the following parameters are set to yes for every poller:

  •  Predictive Service Dependency Checks    
  •  Predictive Host Dependency Checks    
  • Soft Service Dependencies Option

With these settings, Engine should in that case schedule host checks when a service’s state changes, and not notify for the services when the parent host is down, even if it is in SOFT down state.

NB: changing thses settings, requires exporting the pollers’ configuration and restarting (not reloading) Engine.

 

PS: tell me if you don’t feel comfortable/plainly understand with these instructions.
