Admin/M&T Node showing "High Load Average" Alarm with 6 PSN

[umahar]

Hi,

I am working at optimizing an ISE deployment at a Customer's site.

The Customer has ISE 2.0 patch 3 deployed with 2 Admin/M&T and 6 PSNs. I have already pointed out that Cisco recommends a maximum of 5 PSNs for medium size deployment .

However I am seeing an alarm "High Load Average" for the Admin Node even though the system health looks good with CPU and memory both below 25%. and 3K profiled endpoints.

Is it possible that this alarm could be a result of an extra 6th PSN ?

I'll also be opening a TAC case for this

Thanks,

Utkarsh

This is kind of a false positive.  Your load could be 3% and you'll get this message if your daily average is 2%.  Basically it means that the average load percentage has increased due to activity (Authentication, Posture, etc.).  It does not mean that the ISE Nodes are working hard or are over-stressed.

This "alert" will let you know if there is increased activity on your network.  Most of the time it is due to more authentications or the addition of other services (TACACS+, etc.).  If there is an open guest network with a simple portal, then this can also be the cause as people use that.

Thanks Charles.

It looks to be false positive.

I have provided the detailed logs to the TAC engineer.
