Live Tail

Live Tail streams your log events in real time as they arrive — no refreshing, no polling. Events appear within milliseconds of being ingested.

What you’ll need

• Events actively flowing into your project
• A modern browser (Live Tail uses WebSockets)

Step 1: Open Live Tail

Click Live Tail in the left sidebar.

The page starts in a paused state. You’ll see a start button and filter controls at the top.

Step 2: Start the stream

Click Start to connect to the real-time stream.

Log events will begin appearing as they arrive, newest at the top. Each row shows:

• Time — the exact timestamp (updated live)
• Level — color-coded: error (red), warn (yellow), info (green), debug (gray)
• Service — which service sent the event
• Message — the log message

The stream is updated live — you don’t need to scroll or refresh.

Step 3: Apply filters

Use the filter controls to narrow the stream:

• Level — show only error, warn, info, or debug
• Service — filter to events from a specific service
• Environment — show only production, staging, etc.

Filters apply immediately to new events arriving after you set them. Events already visible in the list are not retroactively filtered.

Tip: During a production incident, set Level to error and watch for new error patterns appearing in real time.

Step 4: Pause the stream

Click Pause to freeze the list and inspect events without new ones pushing them down.

While paused, events continue accumulating in the buffer. Click Resume to see the latest events (the buffer will be flushed).

Step 5: Clear and restart

Click Clear to empty the visible list and start fresh. The WebSocket connection stays open — new events will continue to arrive.

This is useful after a deploy when you want a clean view of what’s happening post-release.

Step 6: Click an event for detail

Click any row to open the full event detail in a side panel — the same detail view as Log Explorer, with all metadata fields, event ID, and fingerprint.

You’re done

You now know how to:

• Start and stop the real-time log stream
• Filter by level, service, and environment
• Pause to inspect events, then resume
• Click through to event detail
