Limitations of Grafana in Cloudera Data Warehouse
You need to understand the Grafana capabilities in Cloudera Data Warehouse that Cloudera does not support. Grafana in Cloudera Data Warehouse is intended for use by cluster operations professionals who are familiar with monitoring tools, interpreting metrics, and performing maintenance.
Unsupported features
Storing metrics longer than 15 days or consuming more than 90GB of disk space is not supported. Metrics older than 15 days will be deleted. If the stored metrics consume more than 90GB of disk space, metrics will be deleted regardless of the number of days stored.
Custom dashboards you create in Grafana are lost upon restarting or updating the cluster. Only the default dashboards are supported.
