This is a revision v3 of the Opensearch Prometheus Dashboard here:

https://grafana.com/grafana/dashboards/15178-opensearch-prometheus/

I fixed it, there was a different query in the variable “job” regarding the label value:

Before: label_values(node_uname_info{job=~".kubernetes.|.node_exporters."}, job)

After: label_values(node_uname_info{job=~".kubernetes.|.node-exporter."}, job)

The wrong variable was also invalidating “nodename” and “node” variables as well because they referenced each other.

Additionally, I removed the following views related to K8s:

  • Total Memory
  • Total Memory Free
  • Total Memory Available

Changed:

  • Total Disk Available (Related to Opensearch cluster nodes)
