Querying in ClickHouse CloudThe data in this system table is held locally on each node in ClickHouse Cloud. Obtaining a complete view of all data, therefore, requires the
clusterAllReplicas function. See here for further details.Description
This table contains histogram metrics that can be calculated instantly and exported in the Prometheus format. It is always up to date. Replaces the deprecatedsystem.latency_log.
Columns
metric(String) — Metric name.value(Float64) — Metric value.description(String) — Metric description.labels(Map(String, String)) — Metric labels.
Example
You can use a query like this to export all the histogram metrics in the Prometheus format.http_pool_tcp_buf_bytes
