Logging

Heimdall logs concern everything that happens to Heimdall itself (startup, configuration, events, shutdown, and so on). Logs are written to stdout by default in text format.

Configuration

Logging configuration can be adjusted in the log property of heimdall’s configuration and supports following properties.

  • format: string (optional)

    With text and gelf being the available formats. text is the default format. And gelf defines a JSON format adhering to GELF.

    Example 1. Configuring logging to emit logs using GELD format.
    log:
  format: gelf
    Usage of text (default) format is not recommended for production deployments as it requires more computational resources and is hence slow.

  • level: string (optional)

    Following log levels are available: debug, info, warn, error, fatal, panic and disabled. The last one effectively disables logging. You usually do not want to do this. By default, the level is set to error.

    Example 2. Configuring logging to emit logs in debug level.
    log:
  level: debug
