ClickHouse cluster health monitoring, at a glance
One board of color-coded health checks — replication lag, failed queries, disk, memory, stuck mutations — with alerts to Slack or Discord when something turns red, and again when it recovers.
Built for this, not bolted on
Every health signal in one board
Green, warn or critical indicators for replication lag, readonly replicas, delayed inserts, failed queries, memory, disk, parts-per-partition and stuck mutations.
Alerts to Slack or Discord
Configure one webhook URL and chmonitor posts a message when a check crosses your threshold — and again when it recovers, so you know an incident actually cleared.
A ready audit prompt for your agent
Turn any failing check into a structured prompt — the metric, raw data, relevant system tables and common causes — to paste into an AI agent for a tailored diagnosis.
