Logging settings.

Fields

levels: DirectiveWrapper

The minimum level that logs should be reported at.

Each entry can be one of ERROR, WARN, INFO, DEBUG, or TRACE (in increasing verbosity), with an optional component that specifies the source of the logs.

This setting combined with the contents of the environment variable RUST_LOG, with values from the environment variable overriding the config file.

The environment variable MERINO__LOGGING__LEVELS can be used. This environment variable will completely override the config file, and wil be merged with the envvar RUST_LOG. RUST_LOG takes precedence again.

Examples

The configurations below are identical

logging:
  levels:
    - INFO              # default to INFO
    - merino_web=DEBUG  # noisier logs from merino_web
    - viaduct=WARN      # viaduct's INFO level is too noisy
RUST_LOG=INFO,merino_web=DEBUG,viaduct=WARN
format: LogFormat

The format to output logs in.
