System Map

An interactive sunburst visualization of ClickHouse's observability tools - system tables, diagnostic queries, and metrics organized by subsystem.

Inspired by Brendan Gregg's Linux Performance Tools map and Azat Khuzhin's "Know Your ClickHouse" presentation, the idea is the same: instead of memorizing which of 30+ system tables has the data you need, navigate a visual map organized by the subsystem you're investigating.

How to Use

• Click a segment to select a system table and open its detail panel
• Hover to preview table descriptions
• Search to filter across table names, column names, descriptions, and diagnostic queries
• Run queries directly from the detail sidebar - each table comes with curated diagnostic queries you can execute in one click
