Activity monitoring

Real-time activity stream#

The activity stream is a live feed of everything happening across your desktops and tasks. It uses Server-Sent Events (SSE) to push updates to your browser as they happen. No polling, no refresh needed.

You'll see events like:

• Task created, started, completed, or failed
• Desktop started, stopped, or errored
• Approval requests created
• Agent responses and command outputs

The stream is in the right panel of the Mission Control dashboard. Each event shows a timestamp, the source desktop, and a summary of what happened.

Event types#

Consuming the activity stream#

The activity stream is available at:

GET /api/mission-control/activity/stream

This is an SSE endpoint. In JavaScript:

const eventSource = new EventSource('/api/mission-control/activity/stream', {
  headers: { 'x-api-key': 'your-api-key' }
});

eventSource.onmessage = (event) => {
  const data = JSON.parse(event.data);
  console.log(data.type, data.payload);
};

eventSource.onerror = () => {
  // SSE auto-reconnects by default
  console.log('Connection lost, reconnecting...');
};

Note: if you're using API key authentication, you may need to pass the key as a query parameter since EventSource doesn't support custom headers natively. See API authentication for details.

Metrics dashboard#

Beyond the event stream, Mission Control provides aggregate metrics that update in real-time.

Task metrics include total tasks by status (pending, running, review, done, failed, cancelled), completion rate over the last 24 hours, and average task duration.

Resource metrics include CPU usage per desktop and aggregate, RAM usage per desktop and aggregate, and disk usage per desktop.

These are available in the Mission Control overview panel and via the API:

curl https://lebureau.talentai.fr/api/mission-control/overview \
  -H "x-api-key: your-api-key"

The response includes task counts, active desktop count, and resource aggregates.

Filtering and search#

The activity stream in the dashboard supports filtering by:

• Desktop -- show events for a specific desktop only
• Event type -- show only task events, desktop events, or approvals
• Time range -- focus on recent events or a specific window

Tips#

• Keep the activity stream open while running batch tasks. It is the fastest way to spot failures.
• Use the metrics dashboard to catch overloaded desktops (high CPU/RAM) before they slow down.
• The SSE endpoint stays open indefinitely. Your client reconnects automatically if the connection drops.
• For programmatic monitoring, consume the SSE stream in your scripts to trigger alerts or follow-up tasks based on events.
