Citrix NetScaler ≥12.0 – High CPU Usage on NetScaler VPX Reported on VMware ESXi Version 6.0

Dienstag, August 6th, 2019

Citrix NetScaler – when monitoring CPU utilization on the NetScaler you will periodically notice Management CPU (CPU 0) reporting 100% Utilization – this is normal behavior – the NetScaler’s management CPU performs periodic tasks to compress and roll-over log files, amongst other things.  These processes are designed to take 100% CPU utilization on the Management CPU.

This is an expected behavior with latest NetScaler ≥12.0 build. This is because we have disabled CPU yielding for the VPX.

In case you want to over-ride it they can use CLI command to enable yield:

> set ns vpxparam -cpuyield YES
> show ns runningConfig | grep „cpuyield“
set ns vpxparam -cpuyield YES
