As a consumer of the Elasticsearch Operator I want to have recommendations and playbooks made available to me based on information collected from the cluster so that I can be better enabled to troubleshoot my cluster and prevent it from reaching a critical state.

Recommendations could include:

• node sizing
• number of nodes (topology)
• backing storage
• curation rate/age

Notes:

• Based on number of indices and size of indices
  • figure out how much memory a master node would need
  • how much memory and storage a data node would need
  • how much memory an ingest node would need
  • how much memory a coordinating node would need

Acceptance Criteria:

• Ensure that our current alerts are informative and point to documentation that describes what the alert means, what further investigation steps can be taken, and what actions can be taken to resolve them.
