Netflow Services Cause High CPU Utilization in Polling Engine

Hi All,

We got an issue. After we install NTA, Netflow Service make CPU load high. Netflow service takes up 30% CPU utilization.

Is there any solution for this case?

Below we attach screen capture Orion Server / Polling Server CPU Utilization.

My environment is :

1. NPM 12.0

2. SAM 6.4.2

3. NCM 7.5

4. NTA 4.2.0

Thanks

NTA will take lot of resources so it would be good to re-check on your existing specs and get it increased if possible.

Also observe the pattern when is it exactly remaining high. During DB maintenance is one instance.

How many pollers do you have? How many routers are forwarding traffic to each one? I don't have a rule of thumb, but I'd try utilizing multiple Additional Polling Engine(APE) servers to spread the processing load out.
