Node Count

Styra DAS calculates Kubernetes node count through the following metrics:

  • The node count for the Kubernetes cluster is sampled hourly from data returned by the Kubernetes API Server.
  • The node count displayed in the Usage pane is the average of those samples over the last month.

Node Count through the Styra DAS API​

The following command displays the current Kubernetes node count as reported by the Styra DAS datasources-agent API:
