log

Documentation

Overview

Package log provides a logging facility that is used by this library, and which can be configured to piggyback on another logging facility where available. If not explicitly configured, this will log messages using the Go standar library log package, filtered according to the log level set in the `DD_LOG_LEVEL` environment variable (or `ERROR` if none is set).

Custom logger intergrations are configured by calling the SetBackend function.
