ClickHouse® monitoring with real-time dashboards and alerting

CHOps provides comprehensive monitoring for ClickHouse® clusters. The cluster overview page shows disk, memory, CPU, uptime, and connection status for every node. Custom dashboards let you visualize any metric using SQL-driven charts with 12+ visualization types.

The query profiler generates flame graphs from ClickHouse® trace logs, showing exactly where query execution time is spent. Query metrics provide per-second timelines for deep performance analysis. Monitoring playback lets you rewind and replay historical metrics to understand what happened during past incidents.

Alert rules use SQL conditions evaluated on a cron schedule across all cluster nodes. Notifications go to email, Slack, Microsoft Teams, Google Chat, or PagerDuty. Each node is evaluated independently, so alerts identify the specific server with a problem.
