You might observe an error when trying to run commands like "kubectl top nodes":
$ kubectl top nodes
error: metrics not available yet
Usually this is an indication that the metrics scrape interval is set too high in your Prometheus Monitoring configuration.
This can usually be fixed by setting the "scrapeInterval" value to its default value of "30s". You can follow this guide to edit the Helm values of your Prometheus Monitoring application via the Kommander dashboard:
Otherwise, if there is a reason you need this value set to 60s, such as for resource consumption, you can also fix this by manually setting the interval of only the prometheus-node-exporter section of this configuration. Find the appropriate section of the config values and add the following to your yaml:
prometheus-node-exporter:
prometheus:
monitor:
interval: 30s
