# Session Health

If you have [sessions and releases](https://docs.sentry.io/product/releases/setup.md) enabled on Sentry, you can take advantage of the Session Health dashboard. The Session Health dashboard contains a variety of data visualizations to help you discover insights about how your sessions are performing. A session on most web or mobile applications is created for every page (or view) load and on every navigation change. Read more [here](https://docs.sentry.io/product/releases/health.md#sessions).

The charts help you understand trends for your sessions over time, and the customized chart views and toggleable legends allow you to drill down into the metrics you care about most.

## [Prerequisites](https://docs.sentry.io/product/dashboards/sentry-dashboards/mobile/session-health.md#prerequisites)

You must have [sessions and releases](https://docs.sentry.io/product/releases/setup.md) enabled in order to view these insights. Session Health is available only for the Frontend and Mobile modules.

## [Charts](https://docs.sentry.io/product/dashboards/sentry-dashboards/mobile/session-health.md#charts)

For the Mobile dashboard, found on [Sentry Dashboards](https://sentry.io/orgredirect/organizations/:orgslug/dashboards/), you can see widgets like:

* [Crash Free Sessions](https://docs.sentry.io/product/releases/health.md#crash-free-sessionsusers)
* [Total Sessions by Release](https://docs.sentry.io/product/releases/health.md#session)
* Releases
* Session Health
* User Health (Crash Free Users)

The Crash Free Sessions chart extracts out a single status — "crashed" — to highlight the crash free rate of the 5 most adopted releases in the selected projects. In this case, we define "adoption" as the percent of sessions occurring in that release, out of the total number of sessions in the selected projects. This metric is a key measurement to assess the health of your application.

The Total Sessions by Release shows how many sessions occur in each of the 5 most recent releases. The most recent 5 releases are shown.

Looking at the Issues Count widget, you can hover over a count of releases at the bottom of the chart, and click to see a list of releases and any issues associated with them.

You can customize this dashboard by updating filters or duplicating it to create a new dashboard.

## [Releases Table](https://docs.sentry.io/product/dashboards/sentry-dashboards/mobile/session-health.md#releases-table)

At the bottom of Mobile Session Health dashboard is a table listing releases for selected projects.

The table contains key information about each release, including:

* [Crash free rate](https://docs.sentry.io/product/releases/health.md#crash-free-sessionsusers)
* [Total session count](https://docs.sentry.io/product/releases/health.md#sessions)
