Logging

Requirements

Scope is to provide a simple logging mechanism for message and runtime environment metadata that can be used for message tracking and fault analysis, amongst other things.

1. Functionality

R1.1 Shall provide a minimal, but sufficient, metadata model

R1.2 Shall provide implementation for simple log consumption using logstash, including logstash config

R1.3 Shall allow writing/publishing of a log event to several different outputs (think multiple appenders in log4j)

R1.4 Shall allow different log formats for different outputs (JSON, XML, human-friendly, …)

2. Compatibility

R2.1 Must be usable in different runtime environments like: Java standalone, Servlet container, Mule ESB

R2.2 Must be usable with different logging frameworks like: log4j, logback, log4j2, Java Util Logging, JCL

R2.3 Must provide a Soi-toolkit v1 logging backwards compatible implementation

3. Extensibility

R3.1 Must be easily extensible on a code level

R3.2 Must be easily extensible for adding metadata in a simple way

Candidate requirements …

• Runtime configuration of logging, at least log-level and on/off
• payload logging
