# Event Explorer

Browse every event and metric flowing into Foldspace, inspect their properties, and build metrics for usage, conversations, and cost.

Event Explorer is the catalog of every event and metric flowing into Foldspace, and the workbench for turning them into analysis. It spans **product usage**, **conversational activity**, and **AI cost and token consumption**, and it is the foundation the [Dashboard](/user-guides/analytics/dashboard/) widgets and [Reports](/user-guides/analytics/reports/) are built on.

  
  
  

## How it fits together

Every metric is assembled from the same pieces:

1. Pick an **event or metric** (for example, Action Called).
2. Choose how to **count** it: unique conversations/users, or an **aggregate** (sum or average) of a numeric property.
3. **Filter** and **break down** by any property.
4. Chart it, or save it as a [Report](/user-guides/analytics/reports/) or [Dashboard](/user-guides/analytics/dashboard/) widget.
