chmonitor vs Grafana

ClickHouse-native monitoring vs a general-purpose dashboard

Grafana with the Altinity or official ClickHouse plugin is a genuinely great, flexible dashboarding tool for any data source you wire up. chmonitor does one thing: it reads ClickHouse system tables directly and ships every page pre-built, plus an AI agent, a recommend-only query/MV advisor, and ClickHouse-aware alerting. Here's the honest, row-by-row comparison.

Feature matrix

chmonitor vs Grafana + ClickHouse plugin

Where each tool actually wins — Grafana included.

chmonitorGrafana + ClickHouse plugin
Setup time Point at your ClickHouse host — Docker, Helm, or Cloudflare Workers, ~5 min Install Grafana, add the ClickHouse data source (Altinity or official plugin), then build panels
Pre-built ClickHouse monitoring Queries, merges, parts, replication and health ship as complete pages — no query-writing The plugin gives you a SQL editor and macros; you write or import the panel queries yourself
Visualization flexibility & multi-datasource dashboards Single-purpose: ClickHouse only, fixed page layouts Best-in-class panel library and one pane of glass across dozens of data sources
Plugin & panel ecosystem No plugin marketplace A decade-deep plugin catalog for panels, data sources and alerting
AI agent + MCP server for your cluster Built-in chat agent and an MCP server with ClickHouse-aware tools (query log, merges, replication) No built-in agent or MCP server scoped to ClickHouse system tables
Query advisor (recommend-only) Ranked index/rewrite suggestions with EXPLAIN-based impact estimates; never auto-applies DDL No query advisor — you write and tune SQL yourself
Materialized view / projection designer Recommend-only MV & projection suggestions derived from real query patterns Not a dashboarding concern — no schema-design tooling
Anomaly detection on cluster metrics Statistical baselines per metric, built in Grafana's alerting supports threshold and anomaly-style rules, but you configure and tune each one
Alerting & webhooks ClickHouse-native thresholds and outbound webhooks run everywhere; alert history and inbound-event storage persist with a D1 binding (hosted cloud or a Cloudflare Workers self-host) Mature unified alerting across every connected data source with broad notification routing
Version-aware SQL across ClickHouse releases The query set adapts automatically to the connected ClickHouse version Panel queries are static SQL you maintain yourself across upgrades
Cost Free self-hosted (GPL-3.0); hosted cloud in early access Grafana OSS free; Grafana Cloud from $19/mo + usage (~$6.50 per 1K active series, ~$0.45/GB logs/traces), Enterprise from $25K/yr (2026 list pricing)
Open source / self-host GPL-3.0 — Docker, Kubernetes (Helm), Cloudflare Workers Grafana OSS is AGPL-3.0 and self-hostable

Total cost of ownership

Less to build, less to maintain

Grafana's strength is being a flexible canvas. That flexibility is also the bill: someone has to build and maintain the ClickHouse panels.

Minutes, not a dashboard project

chmonitor ships ClickHouse monitoring as complete pages. Grafana + the ClickHouse plugin gives you a SQL editor and a blank canvas.

Nothing to maintain across upgrades

No panel JSON or hand-written SQL queries to keep in sync with your ClickHouse version — chmonitor's query set adapts on its own.

Advisor + AI agent included

A recommend-only query and MV/projection advisor plus a built-in AI agent — Grafana has no ClickHouse-specific advisor at any price.

Free self-hosted, period

GPL-3.0, no usage-based bill. Grafana Cloud starts free too, then bills per active series/user once you outgrow the free tier.
