# Usage

Usage is a reference page for administrators to view historical usage statistics in their organization's Data Quality & Observability (self-hosted) environment.

![Usage page](https://4121921244-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FWCrP7Albs8DfJjIQxUxw%2Fuploads%2Fgit-blob-4980481cf720ae4c6e298aa638b0ca375e860ef2%2Fdq-admin-usage.png?alt=media)

The tiles across the top of the page break down usage statistics by users, jobs, rules, datasets, and columns for the most recent month. The table below the tiles shows the number of datasets and columns scanned for quality in your organization's environment for the month reflected in the Date column.

The following table shows the descriptions and calculations of the data points included in the tiles at the top of the page.
