Description
Configuration for the logging system.
Simple configuration
Logging system configuration does not contain any root value properties.
Composite configuration
Logging system configuration can contain any conforming composite property. The name of each composite property is the logging namespace being configured.
A conforming composite property is a composite property that contains a valid set of value properties, according to the value property specifications given in the logging namespace configuration section below.
Logging namespace configuration
A logging namespace environment configuration entry is a composite property that occurs within the root logging composite property. Logging namespace environment configuration composite properties may contain the following value properties.
All logging configuration value properties are optional. All default values given below are applied by the logging system and are not present in the logging environment configuration specification.
| Name | Type | Default value* | Description |
|---|---|---|---|
| level | string | INFO | Logging level |
| format | string | see below | Message format specification |
| flush | boolean | true | Whether to automatically flush after each message |

* All default values are set by the logging system.
The default format specification (set by the logging system) if none is supplied or inherited for a particular namespace is:
%Y-%m-%d %H:%M:%S [%thread] %LEVEL - %namespace - %message
Default values for the info-stream and debug-stream properties are set by the logging system for a particular namespace if no other stream specifications have been explicitly provided for the logging namespace and its ancestors.
