Monitor ClickHouse queries in real time
See every running, slow, failed and expensive query as it happens, with duration, memory and rows read, then act: kill a runaway query or review a recommend-only EXPLAIN suggestion for the one that's actually slow.
Built for this, not bolted on
Every query, live
Running, history, failed, slowest and most expensive queries, each with duration, memory, rows read and the full statement. Filter by user and slice by time.
Kill it from the table
Stop a long-running or runaway query directly from the row — no separate SQL client or hand-written KILL QUERY needed.
Recommend-only EXPLAIN suggestions
Run EXPLAIN and get heuristic suggestions — missing PREWHERE, unpruned partitions, unkeyed joins, missing index hints. chmonitor never rewrites or applies anything; you review and apply the fix.
