Average cpu in threshold

[ChrisMiller]

I would like to create a threshold that triggers off the average for all cpus versus off of an individual cpu.  Is this possible in a threshold and if so how?

Hello @ChrisMiller,

For a Windows system running Prognosis Platform, use the NtCpuSystem (NTCPUSYS) record instead of the NtCpu (NTCPU) record.

The NtCpuSystem (NTCPUSYS) record shows combined usage of all the CPUs. The Where Clause should be set to trigger for a percentage greater than XX of the BusyPercent (BUSY) field.

Example Where Clause: BUSY > 70

Thank you,

Scott Baldwin

Scott,

Sorry didn't mention that I'm looking for the average on our nonstop systems.

I have not been able to get a threshold to average CPUs.  I was able to do this with an ANALYST.

If you have the AA product, here is an ANALYST rule that averages our 4 CPUs and logs an event to the problem log.

    NUMERIC       CPU_03_BUSY[0]

Thanks Leon,  I'll give this a go.
