# Overview

> The dashboard home: key numbers, trends, and breakdowns.

The **Overview** is the dashboard home. One screen answers "what is my AI app
doing right now, and how does it compare to before?" Every number respects the
[date-range picker](#date-range) at the top of the page, and each card shows
the change compared to the previous window of the same length.

## KPI cards

| Card               | What it shows                                                                                            |
| ------------------ | -------------------------------------------------------------------------------------------------------- |
| **Total cost**     | Cost for the window, an estimated monthly rate, and the share of LLM spans that got a price.             |
| **Error rate**     | Errored spans divided by total spans.                                                                    |
| **Eval pass rate** | Pass/fail ratio across scored traffic, with the number of checks scored (see [Evals](/dashboard/evals)). |
| **Latency p95**    | p95 step latency, with p50 and time-to-first-token p95 underneath.                                       |
| **Requests**       | Span count, with the LLM-span subset.                                                                    |
| **Tokens**         | Total tokens, split into input and output.                                                               |

For cost, error rate, and latency, the change colors are flipped: red means the
number went up (worse), green means it went down.

## Trend charts

* **Cost over time**: a stacked line chart of cost per minute, split by model.
  The top five models get their own line; the rest are grouped as **Other**.
* **Requests & errors**: spans per minute with errors overlaid.
* **Latency**: p50 / p95 / p99 per minute.
* **By model**: a table of requests, tokens, p95 latency, and cost per model.
* **By agent**: the same, grouped by `agentName`.
* **By workflow**: the same, grouped by `workflowName`. Traces with no workflow
  show as **Ungrouped**.
* **By customer**: cost, requests, and errors grouped by `customer`, with the
  customer's avatar and name. Only traces that set a `customer` appear here.

<Note>
  Models Foglamp can't price show as `(unknown)` rather than `$0`. A missing
  price is never treated as free. You can add a rule on the
  [Pricing](/dashboard/cost) page to price them.

## Date range

The range picker drives every view. Presets: last hour, last 24 hours (the
default), 7 / 30 / 90 days, today, this month, last month, plus a custom
calendar. Future dates are disabled.
