# Analytics in Agents

> An agent's Analytics tab, and the cost of a single conversation and its messages

Every agent measures its own conversations: how many are started, how many messages are sent, how often replies fail, and what they cost. Read it for the whole agent on its **Analytics** tab, or for one conversation in its cost breakdown.

## The Analytics tab

Open an agent and click **Analytics** in its sidebar. The tab has the same [filter bar](https://docs.noxus.ai/platform/analytics/filters.md) as the boards in Analytics: the period, the grouping, and the **Filter** menu, with **Conversation**, **User**, **Version**, **Channel** and **Model**.

| Widget | Shows |
| :- | :- |
| **Conversations started**, **Messages sent** | How much the agent is used |
| **AI model usage cost** | What its conversations cost |
| **AI Operations used** | What its conversations used: each message counts as one, as do nodes the agent runs while chatting |
| **Chats started**, **Messages sent** | The same, over time, split by how they started |
| **Chats started per user**, **Messages sent per user** | Who talks to it |
| **Tokens & cost by model**, **Tokens & cost per user** | Which models answered, and for whom |
| **Failed replies**, **Failed replies over time** | The share of its replies that failed, and when |

**View in workspace analytics**, beside the title, opens **Agent activity** in Analytics filtered to this agent, over the same period.

> [!NOTE]
>
> The Analytics tab needs **View workspace analytics**. To learn what users talk about and how satisfied they are, see [Agent Insights](https://docs.noxus.ai/platform/analytics/insights.md).

## A single conversation

A conversation's cost is in the **Conversation costs** drawer.

**1. Open the drawer**

In a conversation, open the cost breakdown from the action row under a reply. Only replies that called a model have one.

**2. Read the conversation's cost**

The drawer shows the cost of the whole conversation and of each message. Sort the messages to find the most expensive.

**3. Compare it with other conversations**

**Open in agent analytics** opens the agent's Analytics tab filtered to this conversation, over the days it ran. The conversation shows as a chip; remove it to see the whole agent again.

Cost and AI Operations of a conversation include the sub-agent conversations it started.

## What counts

* **Conversations started**: every conversation with the agent. The **Channel** filter narrows them to where they happened.
* **Messages sent**: messages from users and replies from the agent.
* **Failed replies**: replies that ended in an error.
* **Cost**: the tokens each call used, priced at the model's catalogue rate, plus estimates for calls still running or without a usage report. It is what model usage budgets count, and can differ from your provider's invoice. See [AI model usage cost](https://docs.noxus.ai/platform/analytics/billing.md#ai-model-usage-cost).
* **Health checks** that test a model connection are never counted.
