Transforms - Nice CPU Usage Events
From Zenoss Wiki
This is the approved revision of this page, as well as being the most recent.
There are plenty of additional ways to match these events, this is one of the simplest:
Event Class: Perf > CPU
Linux and Windows CPU
# Converts Linux and Windows CPU to a percentage. This is assuming ssCpuIdle is being used for the Linux threshold import re regex = re.search('threshold of .*(CPU).* (exceeded|restored|not met): current value ([\d\.]+)', evt.message, re.I) if regex and device and device.getDeviceClassPath().startswith("/Server/SSH/Linux"): lincpu = re.search("current value ([\d\.]+)", evt.summary) if lincpu: currentcpu = 100 - float(lincpu.group(1)) evt.component = "CPU" evt.summary = "High CPU Utilization: Currently %3.0f%%" % (currentcpu) evt.message = evt.summary if regex and device and device.getDeviceClassPath().startswith("/Server/Windows"): wincpu = re.search("current value ([\d\.]+)", evt.summary) if wincpu: currentcpu = float(wincpu.group(1)) evt.component = "CPU" evt.summary = "High CPU Utilization: Currently %3.0f%%" % (currentcpu) evt.message = evt.summary
Linux Load
# Converts Linux high load events into a prettier message import re if evt.summary.startswith('threshold of high load'): load = re.search("current value ([\d\.]+)", evt.summary) if load: currentload = float(load.group(1)) evt.component = "CPU" evt.summary = "High CPU Load: Currently %2.2f" % (currentload) evt.message = evt.summary
