Monitor ClickHouse query performance with Datadog Database Monitoring

Datadog Database Monitoring for ClickHouse, available in Preview, offers a comprehensive solution for understanding query performance and resource usage in both ClickHouse Cloud and self-hosted environments. It addresses the challenges engineers face in identifying memory-intensive and frequently running queries that can lead to performance issues. The tool provides a unified view of query activity, enabling teams to compare query patterns across clusters and prioritize optimization efforts based on overall system impact rather than just individual query latency. It aggregates metrics such as execution count, duration, memory usage, and I/O activity, helping to identify costly queries. Additionally, it captures and retains completed query samples, allowing for detailed post-incident analysis without the limitations of ClickHouse's own log retention settings. This database monitoring capability aims to help teams reduce costs, enhance performance, and effectively manage incidents by offering real-time and historical insights into query activity across all ClickHouse deployments.
