ClusterAutoscalerWarningEvent#
Troubleshooting hints#
When this alert pops up, multiple endpoints can be checked to fetch additional information:
-
cluster-autoscaler status configMap (
kubectl get -n kube-system configmap cluster-autoscaler-status -o jsonpath='{.data.status}'): gives information about nodes and node groups -
eventrouter logs (LogQL request:
{app="eventrouter"} | json | event_source_component="cluster-autoscaler"): displays last events generated by cluster-autoscaler -
cluster-autoscaler logs might also be useful (streamed on stdout) or LogQL request
{app="cluster-autoscaler"}
Transient errors#
Some errors might have external causes or be transient (this list will be updated when new incidents occur):
