Logging

Athens is designed to support a myriad of logging scenarios.

Standard

The standard structured logger can be configured in plain or json formatting via LogFormat or ATHENS_LOG_FORMAT. Additionally, verbosity can be controlled by setting LogLevel or ATHENS_LOG_LEVEL. In order for the standard structured logger to work, CloudRuntime and ATHENS_CLOUD_RUNTIME should not be set to a valid value.

The logging is via Logrus, so the allowed values for logging config options are determined by that project. For example, ATHENS_LOG_LEVEL can be debug, info, warn/warning, error, etc.

Runtimes

Athens can be configured according to certain cloud provider specific runtimes. The GCP runtime configures Athens to rename certain logging fields that could be dropped or overriden when running in a GCP logging environment. This runtime can be used with LogLevel or ATHENS_LOG_LEVEL to control the verbosity of logs.
