Logs

Overview

The Logs tab streams live stdout/stderr from your running application container. This is your app’s runtime log output — not build logs (those are in Deployments).

Live streaming

Logs connect automatically when you open the tab. The live badge (green, pulsing) shows the connection is active. Click the live / paused toggle to pause or resume streaming.

The stream tails the last 200 lines on connect and receives new lines as they are written.

Filtering

Control	Function
Search box	Free-text filter applied to all visible log lines
all / info / warn / error	Filter by log level (works with JSON-format logs from pino, Winston, etc.)

Logs are sorted newest-first by extracted timestamp.

Log format support

The viewer automatically parses:

• Docker timestamps — 2026-01-14T21:05:46.244Z <message>
• Pino JSON — {"level":30,"time":...,"msg":"..."} (numeric levels: 30=INFO, 40=WARN, 50=ERROR, 60=FATAL)
• Caddy access logs — GET /path → 200 (1.2ms) format
• Express/pino HTTP logs — method, URL, status, duration
• Plain text — displayed as-is

Timestamps are shown in your local timezone.

Crash-loop detection

If Zanode detects your app is crash-looping, a warning banner appears with suggested causes:

• Port already in use — app must listen on the expected port
• Missing module — check build output and dependencies
• Missing file — verify build output path
• Build failed — review build command and logs
• Missing environment variables — check project Settings

Click check settings or filter errors from the banner for quick access to common fixes.
