Slow Queries

Tune a DataStax Enterprise cluster by following recommendations from the OpsCenter Performance Service. For example, view, troubleshoot, and trace slow queries in the Slow Queries section of OpsCenter Performance Service. Examine the slow query log to identify and trace queries that take an excessive time to execute. By default, the slow query log is enabled in DataStax Enterprise.

The query panel indicates when no slow queries are detected.
