# RUM Explorer

## Overview{% #overview %}

The [Real User Monitoring (RUM) Explorer](https://app.datadoghq.com/rum/sessions) allows you to examine data collected from your applications and granular information about your RUM events.

You can:

- Navigate through user sessions
- Investigate performance issues affecting views, resources, or actions
- Troubleshoot application errors and long tasks

## Search and filter{% #search-and-filter %}

Search and filter your RUM events by typing in the search bar and selecting a visualization type in the [RUM Explorer](https://app.datadoghq.com/rum/sessions). You can narrow down, broaden, and shift your focus on subsets of events you are interested in. Use autocomplete suggestions to view facets and recent queries.

## Group{% #group %}

Group the RUM events you have queried into higher-level entities that may help you derive or consolidate information about an issue. To identify event patterns and aggregate events by subsets, see [Group RUM Events](https://docs.datadoghq.com/real_user_monitoring/explorer/group).

To start creating queries and using facets, see [Search Syntax](https://docs.datadoghq.com/real_user_monitoring/explorer/search_syntax).

## Visualize{% #visualize %}

Select a visualization for your filters and aggregations that displays your RUM events in a helpful perspective for you to uncover decisive information.

For example, you can view RUM events in a list, organize RUM data into columns, and see RUM data in a timeseries graph that displays your RUM telemetry over time.

To start visualizing RUM data in the RUM Explorer, see [Create RUM Visualizations](https://docs.datadoghq.com/real_user_monitoring/explorer/visualize).
