Description: The
node_<cpu|memory>_request
metrics and metrics derived from them (node_<cpu|memory>_reserved_capacity
) differ from the output ofkubectl describe node <node_name>
. This is because kubectl filters out terminated pods. See linked issue for more details.Adds a filter for terminated (succeeded/failed state) pods.
Link to tracking Issue: open-telemetry#27262
Testing: Added unit test to validate pod state filtering. Built and deployed changes to cluster. Deployed
cpu-test
pod.The gap is when the change was deployed. The metric can be see spiking up while the
cpu-test
pod is running and then returns to the previous request size after it has terminated.
