Internal Thunder Observability Agent (iTOA)
The internal Thunder Observability Agent (iTOA) is an in-built capability in ACOS that can be configured for any vThunder device to publish the performance metrics and syslogs on the cloud monitoring tool.
The supported vThunder metrics and logs are listed below:
Supported vThunder Metrics
The following table lists the supported vThunder metrics:
