StarRocks Monitoring and Maintenance

Observe and maintain a running StarRocks cluster: health metrics, compaction, tablet repair, statistics, and routine upkeep.

When to Use

• Checking cluster/BE health, disk usage, or tablet distribution
• Inspecting running queries and killing runaway ones
• Diagnosing or triggering compaction
• Repairing or rebalancing tablets/replicas
• Collecting statistics for the cost-based optimizer (CBO)
• Planning daily/weekly/monthly maintenance
