Logging

GOLOG_LOG_LEVEL

Specifies the log-level, both globally and on a per-subsystem basis. Level can be one of:

• debug
• info
• warn
• error
• dpanic
• panic
• fatal

Per-subsystem levels can be specified with subsystem=level. One global level and one or more per-subsystem levels can be specified by separating them with commas.

Default: error

Example:

GOLOG_LOG_LEVEL="error,someguy=debug" someguy

GOLOG_LOG_FMT

Specifies the log message format. It supports the following values:

• color -- human readable, colorized (ANSI) output
• nocolor -- human readable, plain-text output.
• json -- structured JSON.

For example, to log structured JSON (for easier parsing):

export GOLOG_LOG_FMT="json"

The logging format defaults to color when the output is a terminal, and nocolor otherwise.

GOLOG_FILE

Sets the file to which the logs are saved. By default, they are printed to the standard error output.

GOLOG_TRACING_FILE

Sets the file to which the tracing events are sent. By default, tracing is disabled.

Warning: Enabling tracing will likely affect performance.
