Real-time analytics means queries that return fresh results in milliseconds over continuously arriving data, not pre-computed reports refreshed on a schedule. ClickHouse is built for this workload: columnar storage, vectorized execution, streaming ingestion, and materialized views that pre-aggregate on write.

Monitoring systems generate continuous streams of metrics, logs, and traces that need to be ingested, stored, queried, and alerted on in real time. ClickHouse handles the volume and query latency that monitoring workloads require, from infrastructure metrics to application logs to security event correlation.
