In the monitoring tab for Composer (Airflow) on Google Cloud there is a graph showing "CPU usage per node". How should the values in this graph be interpreted? What value would indicate that the load is reaching the limit and that there might be insufficient CPU resources available?
The Composer Kubernetes cluster is running on 3 nodes of machine type n1-standard-1.
There is a short description available in the graph but I'm not sure how to interpret it:
"The usage of CPU cores aggregated from all running pods on the Kubernetes node. Measured in core time usage ratio. Doesn't include the usage by system components running on the node."
