How to check CPU Utilization on LTM

It's complexe and it depends the TMOS release.

With 11.5, we introduced HTSplit. That means some TMM works for Dataplane et some others for Controlplane. But not with the same Performance factor and TMM Dataplane can "eat" TMM ressource dedicated for management.

• Dataplane : traffic
• Controlplane : management

Before 11.5, 10% of TMM was used for Controlplane (very roughly). From 11.5, with HyperThread per core:

• Even HT : TMM process (traffic)
• Odd HT : management with 20% max usage and Even TMM can "eat" Odd TMM ressources.

Make sense :) ?
