System Documentation
What problem does it solve?
Diagnoses ClickHouse replication health, Keeper connectivity, replica lag, and queue issues to prevent silent failures and data divergence across clusters.
Core Features & Use Cases
- Replication health checks: evaluate system.replicas, queue sizes, lag, and failover readiness to identify problematic replicas.
- Keeper/ZooKeeper diagnostics: verify Keeper connections, session status, and recent errors to maintain quorum and stability.
- Queue and task analysis: inspect system.replication_queue and related metrics to prioritize remediation of stalled or stuck tasks.
- Use Case: When a replica becomes readonly or experiences significant lag, run diagnostics to locate root causes and actionable fixes.
Quick Start
Generate a replication health diagnostic report for all ClickHouse replicas in your cluster.
