About chmonitor
chmonitor is an open source operations dashboard for teams running ClickHouse. It builds its views directly from ClickHouse system tables, so no exporters or extra storage are required. Engineers can inspect running, failed, slow and costly queries, run EXPLAIN, and stop long queries from the table. A topology map shows nodes, shards and replicas plus the Keeper quorum with metrics for each node, while health checks notify Slack, Discord, PagerDuty or Opsgenie when thresholds are crossed. A built in agent studies schema and query history to suggest tuning, and it can be reached over MCP in read only mode. Self hosting is free, and a CLI is in beta.
Key features
- Live views of queries, merges, parts and replication
- Query history with EXPLAIN and a kill option
- Cluster map covering shards, replicas and Keeper health
- Threshold alerts routed to Slack, PagerDuty and others
- Recommend only AI advisor exposed through MCP
- Data explorer with table lineage and SQL console
