With high vCMP guest counts, the avrd shows sustained ~90% CPU usage on the HOST primary blade.
The avrd will compete with the control plane threads on the guest that share the same core. The guest dataplane runs at higher priority and not impacted. The avrd maintains a database of statistics available via the UI and 'tmsh show analytics vcmp ...'. When avrd is stopped, these statistics will not be available.
For example, 48 guests on B4300 8-blade P8, or 96 guests on B4450 8-blade P8.
Run the following commands on the HOSTprimary blade: clsh bigstart stop avrd clsh bigstart disable avrd
The avrd no longer shows sustained ~90% CPU usage on the HOST primary blade with high vCMP guest counts.
