Environment

• Avi version 22.1.x, 30.2.1, and 30.2.2 are affected due to this issue

Cause

• In the Cloud Services tier, the Controller only consumes the licenses it requires from the license pool on the Pulse portal. However, this results in the Controller displaying 100% license utilization.

Resolution

• This event is only relevant for the Enterprise tier, where the Controller consumes licenses uploaded directly to it. If the Controller is in the Cloud Services tier, this event can be ignored. Instead, monitor the Pulse dashboard for the actual license exhaustion.
• This issue is resolved in Avi version 31.1.x and above.
