# system.histogram_metrics

<Info>
  **Querying in ClickHouse Cloud**

  The 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](/reference/system-tables/overview#system-tables-in-clickhouse-cloud) for further details.

<h2 id="description">
  Description
</h2>

This table contains histogram metrics that can be calculated instantly and exported in the Prometheus format. It is always up to date. Replaces the deprecated `system.latency_log`.

<h2 id="columns">
  Columns
</h2>

* `metric` ([String](/reference/data-types)) — Metric name.
* `value` ([Float64](/reference/data-types)) — Metric value.
* `description` ([String](/reference/data-types)) — Metric description.
* `labels` ([Map(String, String)](/reference/data-types)) — Metric labels.

<h2 id="example">
  Example
</h2>

You can use a query like this to export all the histogram metrics in the Prometheus format.

```sql theme={null}
SELECT
  metric AS name,
  toFloat64(value) AS value,
  description AS help,
  labels,
  'histogram' AS type
FROM system.histogram_metrics
FORMAT Prometheus
```
