Notes

Compliance Report

Where:

• Files whose path suggest they're for testing are skipped. 
• XML is sanitized first: 
  • To remove XML comments. 
  • To fix XML that has bad data ahead of <?xml, including a lot of copyright headers. (Java may fare better than Python, but they're technically invalid).
• A few documents (properties and XML both) are unparseable for other reasons, so they're reported as such in Notes.
• Analysis is pattern-based and fairly superficial: 
  • There are 300+ files. 
  • Even within EELF, there's a lot of variation. 
  • For Logback, EELF is identified by characteristic MDC keys, and compliant logging by telltale MDC serialization, markers and escaping (all of which seem to be non-existent in non-compliant logging). 
  • For Log4j, likewise, but slightly more forgiving when sniffing for EELF, and there are no instances of compliant logging for Log4J, so nothing to look for. 
• Summarizing: 
  • Log provider configuration is in shambles. 
  • Ad hoc configurations predominate. 
  • EELF remains ubiquitous. 
  • Log4j, too, and note the number of Log4j properties files (→ Log4j v1, which does not support escaping, and therefore cannot emit logs that can be reliably indexed). 
  • Compliant logging:
    • Is rare in component configuration (i.e. inside projects).
    • Is slightly more common in OOM overrides (which generally take precedence where they exist).
