Logs

Kubus streams logs into the bottom dock and can aggregate many pods into one view. A Deployment's logs read as a single, colour-coded stream instead of a dozen separate kubectl logs -f windows.

The aggregated log viewer The aggregated log viewer
Logs from every pod of a workload, each pod in its own colour.

Opening logs

  • A pod: ⋮ menu → Logs.
  • A workload (Deployment, ReplicaSet, StatefulSet, DaemonSet): ⋮ menu → Logs aggregates every matching pod into one stream.
  • A Service: ⋮ menu → Logs follows the pods behind it.
  • From the palette: Ctrl+K, find the resource, Tab → Logs.

Each stream opens as its own tab in the dock, so you can watch several at once. Close the focused tab with Ctrl+W / Cmd+W (desktop app).

Time range

Pick how far back to read, from the toolbar:

Mode Behaviour
Live tail Follows new lines as they arrive (the default).
10m / 1h / 6h / 24h ago Loads logs since that point, no follow.
Terminated The previous container's logs: what a crash-looping pod said before it died.

Debugging a crash loop

Use Terminated to read the logs from the last run of a container that keeps restarting. The most useful lines are usually the ones from just before it exited.

Make sense of the stream

  • Per-pod colour: every pod gets a distinct colour, so you can tell who said what in an aggregated stream.
  • Log levels: Kubus detects each line's severity (JSON, logfmt, klog and plain formats) and shows E / W / I / D / T count chips in the toolbar. Click a chip to keep only that level, or several to combine them. Error and warning lines also get a subtle tint so they stand out while scrolling.
  • Regex filter: type a pattern to keep only matching lines.
  • Follow: toggle live following on or off, for example to scroll back without the view jumping.
  • Wrap: wrap long lines instead of scrolling sideways.
  • Timestamps: off, local time, or UTC.
  • Syntax highlighting: Kubus recognises JSON and logfmt and highlights levels (error, warn, …) so problems stand out.

Defaults for tail length, wrapping, timestamps and highlighting live in Settings → Logs & terminal.

Export

  • Download the current buffer as a text file.
  • Copy it to the clipboard.
  • Clear the on-screen buffer to start fresh.
  • Maximise the dock when you need room to read.
