I'm exploring using collectd (5.0.1 on centos) as an adjunct to monitoring. In most cases I'll be using non-persistent notifications just to cut down on noise.
At it is I've followed the docs here http://collectd.org/wiki/index.php/Notifications_and_thresholds and have basic thresholds/notifications working. As it stands, hosts that have plugins, which are configured with thresholds, have alerts sent when either the stat being monitored is not within the threshold boundaries or the collectd server has not seen a stat from a host within the past N seconds. What about transient outages such as a network blip? In that case collectd would generate notifications for host(s)/stat(s). When the network starts working, stat collection resumes. It might be nice if there were a corresponding OK message indicating that we are now seeing stats come in for the same set of servers. It might also be nice from the perspective of measuring 'flap' or just the outage window if we were able to get the failure notices and also a transition notice where stats resume. I just want to note this is different than regular plugin thresholds which can generate the FAILURE/OK events as boundaries are crossed. Does this seem right? I am still getting my feet under me with collectd so correct me where I have it wrong. Thanks in advance, -- J. _______________________________________________ collectd mailing list [email protected] http://mailman.verplant.org/listinfo/collectd
