Dashboard Overview
A tour of the Overview page — your landing screen after login, showing aggregate stats, charts, and navigation.
What you see after logging in
The Overview page is the first screen you land on after authenticating at app.trenchcoat.io. It gives you a high-level picture of your AI agent activity for whatever time window you have selected.
If you have not sent any events yet, the page will show empty-state prompts with a quick link to create your first API key and connect a plugin. Once data is flowing, the page fills in automatically.
Metric cards
Five summary cards run across the top of the page. Each reflects totals for the selected date range.
| Card | What it counts |
|---|---|
| Total Sessions | Distinct Claude Code sessions in the period. Each session counts once, however many days it spans |
| Total Events | Every event received (session_start, tool_use, tool_result, …) |
| Tool Uses | Tool events only — how many times any tool was called |
| Agent Calls | Subagent completions |
| Active Days | Calendar days with at least one event |
Beneath Total Sessions sits a coverage line: of all sessions recorded to date, how many carry usable per-turn token data. It is corpus-wide while the card is scoped to the selected range, so the two are not meant to subtract. Most historical sessions carry no token data and cannot be repaired — their transcripts are gone.
Charts
Daily Activity
Activity per day across the selected range. Useful for spotting trends — a spike usually means a busy work day.
Top Tools
A bar chart ranking your most-used tools by call count, highest first. An instant read on what your agents actually rely on.
Daily Cost
Estimated spend per day.
Cost is an estimate. Trenchcoat prices its own reconstructed token counts
against a community-maintained rate table (LiteLLM), not Claude Code's billed
figure. A model with no pricing row is excluded rather than counted as $0.00,
so a day containing unpriceable models reads low.
The hourly activity distribution lives on the Activity page, not here.
Date range picker
The date range picker sits in the top-right corner of the page. All charts and metric cards update instantly when you change the range.
Presets:
- Today
- Last 7 Days
- Last 30 Days
- Last 90 Days
You can also click Custom Range to choose any start and end date with the calendar picker. The selected range persists as you navigate between pages in the dashboard.
Navigation sidebar
The left sidebar is present on every dashboard page. Sections:
- Overview — this page
- Sessions — browse and inspect individual Claude Code sessions
- Tools — aggregated tool invocation data
- Skills — skill activations, and the tool calls each one triggered
- Agents — subagents by type, with lineage, tokens and cost
- Evals — tagged experiment runs and their outcome scores
- Cost — spend over time, by model and by session
- Activity — event stream and raw activity log
- Teams — manage shared workspaces and members
- Settings — API keys, account preferences
