What's new in chmonitor
Release notes, product updates, how-to guides, and ClickHouse diagnostic deep-dives from the team building the open-source ClickHouse monitoring dashboard.
Release
8New versions, features, and fixes shipped to chmonitor.
- chmonitor v0.3.9 — Know who runs whatOct 24, 2026
Every dashboard query now says who ran it and from where, a new Dashboard Usage page reads that back, the users page shows activity and last login, and alerts thread on Matrix and Telegram.
- chmonitor v0.3.8 — Find what nobody readsOct 22, 2026
The advisor finds unread tables, unread columns and unused projections, a read-only detached parts triage, hot query shapes for one table, new insights, and repeat reminders that know when to stop.
- chmonitor v0.3.7 — An agent that reads your pageOct 11, 2026
A smarter AI agent that can read any dashboard page, alerts you set up from a health check, PeerDB stall and pattern alerts, task-based navigation, and a redesigned docs site.
- chmonitor v0.3.6 — Less menu. More cluster.Oct 3, 2026
Everything since v0.2 in one place: a sidebar cut from 16 menus to 5 task groups, a faster dashboard, Cloud, Postgres and PeerDB monitoring, alerting, AI, and new compare tools.
- chmonitor v0.3.5 — PeerDB alerting, a local CLI, and a quieter sidebarSep 27, 2026
75 commits and 185 pull requests across five weeks: PeerDB grew a full alert cycle, the Rust CLI learned local named connections, the sidebar learned to stay out of the way, and the public API surface got hardened.
- chmonitor v0.3.4 — Tools, Schema Compare, workspace rolesAug 20, 2026
After four days of agents working day and night — 106 PRs, 267 comments — v0.3.4 is the tag for Tools, workspace roles, Schema Compare, and the shift to self-hosted licenses.
