Application Logs

Application logs show the real-time stdout and stderr output from your running processes. Use them to monitor application behavior, debug issues, and track requests.

Viewing Logs​

  1. Go to your application in the dashboard
  2. Click App Logs in the application navigation

Filtering by Process​

If your application has multiple processes (web, workers, etc.), you can select which process to view logs for. Use the process selector to switch between:

  • Web process logs (HTTP request handling)
  • Worker process logs (background jobs)
  • Any other named processes you have defined

Standalone Mode​

In standalone mode, logs are streamed from the Docker container running on your server. You see output from the single container instance for the selected process.

Cluster Mode​

In cluster mode, logs are aggregated from services running across all nodes in your Docker Swarm cluster. This means you see combined output from all replicas of a process, regardless of which node they are running on.

Tips​

  • Make sure your application writes logs to stdout/stderr rather than to log files. Docker captures stdout/stderr automatically, and Appliku reads from Docker's log stream.
  • Structured logging (JSON format) can make it easier to search and filter log output.
  • For persistent log storage and advanced searching, consider forwarding your logs to an external service (e.g., Papertrail, Datadog, or Loki).
  • Build-time logs are available separately in the Deployments section.
