Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.chartbeat.com/datastream/getting-started/metrics-and-dimensions.md). # Metrics and Dimensions Datastream exports all of the following dimensions and metrics to clients. Each row of data in a Datastream file represents a completed user session where a session corresponds with the time a visitor spent on a single page before either going to a new page or leaving your website. Unless otherwise mentioned, data should be considered “raw”, meaning it has been unaltered by Chartbeat. {% hint style="info" %} **Note:** All data of type STRING is UTF-8 encoded. {% endhint %} ### Page Dimensions | **Name** | **ID** | **Description** | **Data Type** | | ----------------- | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------- | | Host | host | The Chartbeat dashboard identifier that the page’s tracking code is instrumented to track. | STRING | | Domain | domain | The DNS domain from which the tracking request was made from.
