# Overview

> The dashboard home — KPIs, trends, and per-model/agent/workflow/customer breakdowns.

The **Overview** is the dashboard home: a single screen that 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
KPI shows a delta against the immediately preceding window of equal length.

## KPI cards

| Card               | What it shows                                                                                                           |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------- |
| **Total cost**     | Summed cost for the window, with a `~$/mo` extrapolation and the share of LLM spans that received a price (`% priced`). |
| **Error rate**     | Errored spans ÷ 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 TTFT p95 underneath.                                                                     |
| **Requests**       | Span count, with the LLM-span subset.                                                                                   |
| **Tokens**         | Total tokens, broken into input/output.                                                                                 |

Deltas for cost, error rate, and latency are **inverted** — 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 series; the rest roll into **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
  roll into **Ungrouped**).
* **By customer** — cost, requests, and errors grouped by `customer` (the
  end-customer a call serves), with the customer's avatar and name. Only traces
  that set a `customer` appear here.

<Note>
  Models Foglamp can't price are labelled `(unknown)` in the breakdowns rather
  than shown as `$0` — a missing price is never silently treated as free. 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 (default),
7 / 30 / 90 days, today, this month, last month — plus a custom two-month
calendar. Future dates are disabled.
