To learn more about interpreting these graphs, please review our article on determining the cause of HTTP response codes.

Node and container metrics

You may view the CPU, Remaining credits, Memory, and Storage utilization of a node and containers running on the machine by clicking the View metrics button for each node in a cluster.


CPU credits for burstable nodes

Small and Medium nodes are burstable tier virtual machines. As such, Small and Medium nodes can temporarily use more than 100% CPU capacity for a temporary amount of time.

Database metrics
