Monitor ClickHouse query performance with Datadog Database Monitoring

Datadog’s new Database Monitoring for ClickHouse provides a unified view of query performance for both cloud and self-hosted deployments, addressing the difficulty of understanding resource usage from query activity. It achieves this by collecting aggregated query metrics and capturing completed query samples, allowing teams to identify costly queries (even those running frequently but moderately slow) and reconstruct incidents with detailed execution context. This helps engineers optimize workloads, reduce costs, and proactively address performance issues beyond just identifying the single slowest query.
