# Events & metrics

Every event Foldspace receives, organized into categories, each usable as a metric with smart defaults.

**Path:** Analytics → Event Explorer

Every event Foldspace receives is available as a metric. The picker organizes them into categories so you can find the signal you want.

## Categories

| Category | Count | Examples |
| :--- | :--- | :--- |
| **Conversation Interactions** | 8 | Action Called, Action Registered, Action Response Received, Conversation Started, Message Sent, Agent Handoff, Message Rated, UI Element Rendered |
| **Conversation Signals** | 5 | User Intent, User Sentiment, Resolution Status, Agent Gap, Primary Language |
| **Application Event** | 2 | Identify, Agent_Interactions |
| **Web Tracking** | 5 | Any event, Lead capture, Page view, Session init, UTM |

## The metric detail

Select a metric to see:

- **Description** — what fires the event (for example, Action Called: "Fired each time the AI agent decides to use a specific action").
- **Tracked as** — the underlying event name (for example, Action Called is tracked as `Chat Action Call`; Identify is tracked as `Identify`).
- **Total events** and **Last seen** — volume and recency, so you can confirm it's flowing.
- **Smart defaults** — applied automatically when you add the metric: a default **Metric**, **Counting** method, and **Breakdown**. For Action Called they are Unique Conversations / Unique Conversation / Action Key; for Identify they are Unique Users / Unique User / User Role.

## Verify a custom event

Custom events you send with [`foldspace.track()`](/reference/track-api/) show up here under the name you passed:

1. Trigger the action in your product once so the event fires.
2. Find the event name in Event Explorer (names are case-sensitive).
3. Confirm its properties match what you passed.
