ClickHouse Monitoring Dashboard

The simple Next.js dashboard that relies on system.* tables to help monitor and provide an overview of your ClickHouse cluster.

Features:

• Query monitor: current queries, query history, query resources (memory, parts read, file_open, ...), most expensive queries, most used tables or columns, etc.
• Cluster monitor: total memory/CPU usage, distributed queue, global settings, mergetree settings, metrics, etc.
• Tables and parts information: size, row count, compression, part size, etc., at the column level detail.
• Useful tools: Zookeeper data exploration, query EXPLAIN, kill queries, etc.
• Visualization metric charts: queries and resource usage, number of merges/mutation, merge performance, query performance, etc.
