The Activity Summary widget provides a high-level summary of the Cloud Functions environment. It helps us to understand and monitor the overall health and performance of the Cloud Functions-enabled service. The metrics provide us with the following details:
- The usage rate of the OpenWhisk actions, displaying the number of times they were invoked.
- The overall rate of failure across all actions. We can spot an error and isolate the services that have the errors; we can do this using activity log widgets.
- The performance of the actions, displaying the average completion time that is attached to each action.
