I was going through the answers to this question:
http://programmers.stackexchange.com/questions/54008/what-information-must-never-appear-in-logsWhat information must never appear in logs?
And noticed that nobody mentioned this particular attribute. It's something I find useful- whenever any logging is added to the system as a result of tracing a particular issue raised in the bug tracker, or adding a feature, I tend to include the ticket number of the related helpdesk element.
This means that when going through the log, any programmer can cross reference each log message with the associated ticket number. Now I understand that using proper VCS/helpdesk integration means most commits are attached to a ticket number anyway- but over time it makes it easy for us to diagnose problems on inspection whenever a log message comes up.
However it still makes me a bit uneasy leaving this in the logs. The problem is, I can't think of a scenario where this could become a problem. I'm hoping SE can help me out.
By the way- I'm talking about the "verbose" log level. This is never done in a logging level that will appear in production.
