I'm a Big Brother user taking Zenoss for a spin right now. The software is definitely slick, and has many things we've found lacking in BB. One item I'm curious about is generating alerts when a threshold has been exceeded for a specified amount of time.
For example, I'm not interesting if the CPU spikes to 100% for a few seconds, but I am interseted if say the CPU stays above 75% on average for 10 minutes. From my understanding, it is possible to do this in Zenoss but I just want to make sure this is correct (and save me some time testing. Hehe). One thing I'm curious about is the polling interval. From my understanding, since CPU is pulled via SNMP, the SNMP Performance Cycle Interval determines the pulling time for the CPU and all other SNMP performance values. When a device is pulled, is the value grabbed (in this case cpuPercentProcessorTime for a Windows box) an average based on the SNMP Performance cycle or unique value at the instant the OID is queried (or for that matter, is it the OID you query that determines the average and not the monitoring agent itself)? There seems to be a couple ways of pulling this off from what I understand: 1. Create an alert with a delay of say 10 minutes so that if the threshold is exceeded twice (since we assume a 5 minute performance pulling interval) its safe to assume the threshold has been exceeded for 10 minutes? 2. Create an escalate count of 2 (which would equal 10 minutes with a 5 minute performance pulling interval) that would elevate the status from say warning to error. Does the escalation keep escalating so if you set it at info, it will eventually reach critical if the threshold keeps getting exceeded? Any help would be appreciated and many thanks! -Chris -------------------- m2f -------------------- Read this topic online here: http://community.zenoss.com/forums/viewtopic.php?p=10351#10351 -------------------- m2f -------------------- _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
