We are using OpenNMS to monitor a pool of servers, and we have a problem with SMTP in one particular box. OpenNMS is "spamming" us all the time with DOWN/RESOLVED messages for that particular service in that server, and I wanted to mute those notifications momentarely but couldn't find how to do that. I know that I can disable ALL notifications or disable SMTP in ALL servers, but that's not what I want.

I'm used to muting a particular service in Nagios, but is it possible in OpenNMS?

  1. Go to Home / Search / Node List and select the specific Node you have a problem with.
  2. In the Node Management page goto Admin > Manage and Unmanage Interfaces and Services.
  3. Deselect the service you wish unmanaged and click Apply Changes.

In the availability view of the node the SMTP service should now read something like "Forced Unmanaged".


I think you're stuck with creating a Scheduled outage for the node in question OR unmanaging the service in question on the specific node.

Admin -> Manage and Unmanage Interfaces and Services 
Uncheck SMTP for the right interface and Apply Changes

Return to the node's page and run a rescan to activate the changes.
