ClickHouse Monitoring for Data Engineers

As a data engineer, you care about query performance, data integrity, and storage efficiency. Clustersight surfaces the metrics that affect your pipelines.

Your Biggest Pain Points

Silent pipeline failures from broken parts. A broken part silently causes queries to fail or return incomplete results. Clustersight detects broken parts immediately and tells you which table is affected.

Slow queries with no visibility. Clustersight's Query Inspector surfaces slow queries, their resource consumption, and links to optimization guidance.

Storage growing faster than expected. Clustersight's disk panels give you per-table storage breakdowns with compressed vs uncompressed sizes.

What You Get

• Query Inspector — identify slow queries, duration, memory usage, read bytes
• Broken parts panel — immediate visibility into data integrity issues
• Disk usage by table — sorted by size, with compression ratios
• Mutation queue — know when ALTER TABLE UPDATE/DELETE operations are stuck
• Part count monitoring — prevent "too many parts" errors before they hit
