Alerts by Avarge

Hi All,
I've created a trigger to measure CPU utilization by performance counter, and set the trigger that if CPU utilization is 95% for more than 5 minutes, then send me an alert.
{HostNameerf_counter[\Processor(_Total)\% Processor Time].avg(5m)}>95

But what happens is that each time the CPU gets to 95% I get an alert.
It ignores completely the 5 minute average I requested.
The server monitored is a windows server.
Thanks in Advance.

Hi,

Try your trigger with 300 seconds instead of 5 minutes.

{HostName:Perf_counter[\Processor(_Total)\% Processor Time].avg(300)}>95

Does it help?

Hi Ignus,
That didn't help either.

Ingus,
Does this trigger expression is valid for Windows servers or only for Linux Servers?
{system.cpu.util[,,avg1].avg(600)}>90

Hi,

1) Is the performance counter actually returning anything in Latest data?

perf_counter[\Processor(_Total)\% Processor Time]

2) {system.cpu.util[,,avg1].avg(600)}>90 is valid for both Windows and Linux

But why wouldn't you consider using {system.cpu.util[,,avg15].last()}>90 ?
That will give you the average for last 15 minutes and does not use the "avg" trigger function in Zabbix server (increases the actual load of trigger processing).
