# Console

> The visual UI for your running iii system.

<Note>
  The console is the visual UI for iii systems. It lists workers, functions, and triggers, and shows
  traces, logs, and metrics from the iii-observability worker. For scripting or agent integration,
  call worker functions directly.
</Note>

## Launch the console

The console connects to a running iii engine, so start the engine first, then launch the console in
a second terminal:

```bash theme={"theme":{"light":"catppuccin-latte","dark":"dark-plus"}}
iii console
```

Open `http://127.0.0.1:3113` in your browser.

<Note>
  Naming review: `iii console` is verb-shaped (launches the console) but doesn't follow the `iii
      noun verb` convention used elsewhere in the CLI. Flagged for naming review per
  `project-rules/cli.md`.
</Note>

## Workers page

Lists every worker process currently connected to the engine. Each row shows the worker's name (or
short ID), the project / framework / language it reported, a runtime badge with SDK version, an
optional isolation badge (`libkrun`, `docker`, etc. as reported by the worker), IP, PID, the number
of functions it has registered, in-flight invocations, and how long it has been connected.

Selecting a worker opens a detail panel with full metadata, the project / framework / language
fields the worker reported, live metrics (memory breakdown, CPU, event-loop lag, uptime), and the
list of functions the worker has registered.

<Info title="Isolation badge">
  The isolation badge reflects what the worker self-reports via the `III_ISOLATION` environment
  variable. The libkrun launcher injects `III_ISOLATION=libkrun` automatically; for container or
  Kubernetes deployments, set `III_ISOLATION=docker` (or similar) yourself. Workers that don't set
  the variable show no badge.
</Info>

## Functions page

Lists every registered function, grouped by namespace prefix (the part before `::`). A toggle in the
header includes or excludes system functions.

Select a function to open its detail panel. The panel includes:

* A description (pulled from the function's request schema, if present).
* A request-body editor pre-filled from the request schema as a template.
* An **Invoke** button that calls the function with the editor's payload.
* A result view that shows the response (or error) with the call duration.

## Triggers page

Lists every registered trigger with **All / HTTP / Cron / Event / Other** filter tabs that show
counts per type. Each row shows a summary (HTTP method and path, the readable cron expression, or
the event topic), a type badge, the `function_id` it routes to, and the function's description.

Selecting a trigger opens a detail panel with type-specific testing tools:

* **HTTP**. Method dropdown (`GET`/`POST`/`PUT`/`PATCH`/`DELETE`), path parameter inputs, a
  query-parameter builder, a JSON body editor for write methods, and a **Send Request** button.
* **Cron**. Schedule (human-readable + raw expression), next-run preview, status, and a **Run Now**
  button that fires the bound function immediately.
* **Event**. Event topic display, a JSON payload editor, and an **Emit Event** button.

State-bound triggers don't have a dedicated tester on this page; fire them by editing the relevant
entry on the [States page](#states-page).

## States page

Browser for the engine's key-value state store. The layout is groups list (left), items table
(center, sortable on Key / Type), and a detail panel (right) that opens on row click.

Supported operations:

* **Add**. Open the Add Item modal to write a new entry; persisted via `state::set`.
* **Edit**. Update the value inline from the detail panel; fires any registered `state:updated`
  triggers.
* **Delete**. Remove an entry from the detail panel; fires any registered `state:deleted` triggers.

Use the search bar to filter items by key; pagination handles large groups. The page does not push
live updates over WebSocket; use the refresh control after external writes.

## Streams page

Live WebSocket monitor for the messages flowing through the engine's stream connections. The header
surfaces inbound / outbound counters, total bytes, and latency. A subscriptions bar lists the
streams you're currently watching (subscribe and unsubscribe through the modal).

Message rows show timestamp, stream name, event type, a truncated data preview, and message size. A
direction filter and pause/resume controls let you isolate flows; selected messages open a detail
panel with the full payload. The filtered set can be exported to JSON.

## Queues page

Lists durable queue topics with **Topic**, **Broker**, a **DLQ** badge (when dead-lettered messages
exist), and **Subscribers** columns. Selecting a topic opens a resizable detail panel with two tabs:

* **Overview**. Live topic stats and a JSON publisher for sending test messages.
* **Dead Letters**. Failed messages with retry and delete actions.

Counts and stats refresh by polling. Keyboard shortcuts: `j` / `k` to move through the list, `Enter`
to select, `1` / `2` to switch tabs.

## Traces page

OpenTelemetry trace visualization across four view modes:

* **Waterfall**. Timeline view with spans laid out by start time and duration. Default.
* **Flame Graph**. Stack-based view; wider bars mean longer-running spans.
* **Trace Map**. Topology graph showing service-to-service edges via parent-child spans.
* **Flow**. Node-based execution flow of parent-child span relationships.

Filter controls cover trace ID, service name, span / operation name, status (`ok` / `error` /
`unset`), duration range, time range, and arbitrary span attributes; results can be sorted by start
time, duration, or service. The selected span's detail panel includes its name, service, duration,
status, IDs, tags, logs, errors, and baggage.

## Logs page

Structured OpenTelemetry log viewer. Each row shows timestamp, severity badge
(`DEBUG`/`INFO`/`WARN`/`ERROR`), a truncated trace ID, the source function / service, the message,
and a context-field count badge. Expanding a row reveals the full attributes, resource metadata, and
trace context.

Filters cover severity, time range, and full-text search across message / trace ID / source. The
trace ID on each row is clickable: it pivots the view to show only logs from that trace, which also
lets you jump to the corresponding entry on the [Traces page](#traces-page).

## Configuration

The console reads engine and observability settings from CLI flags and environment variables.

To list every flag the binary accepts (with its default), run:

```bash theme={"theme":{"light":"catppuccin-latte","dark":"dark-plus"}}
iii console --help
```

The corresponding environment variables share the same set; each flag's help text names the env var
that overrides it. The **Config** page in the sidebar shows the resolved values at runtime (the
engine endpoints, ports, OpenTelemetry settings, and version the console is currently using), so you
can confirm what's actually in effect without re-reading the flags.
