Summary

Problem it solves

Have a set of proven scripts on hand for the daily check of contention, performance, and configuration in Cassandra, without having to rebuild them every time.

Who it is for

DBAs or system administrators who operate Cassandra in production and need a repeatable technical checklist per node.

Who it is not for

Anyone who needs the DataStax Enterprise upgrade procedure (see the dedicated guide in the catalog).

  2. Compaction backlog (nodetool compactionstats)
  3. Timeouts and dropped mutations/reads in the log
  4. Overall node and cluster status (nodetool status)
  5. Reviewing performance: per-table latencies (nodetool tablestats)
