Description Eric Herman 2009-09-30 01:36:30 UTC
When looking at a catalina.out, it's not always clear what the environment variables resolved to at the time the process was started. This information may be echoed to the screen if not started by hand, but that may be gone by the time we're looking at the log file. It would be helpful to log these variables to the catalina.out at startup.

Created attachment 24325 [details] example patch for logging environment variables to catalina.out at start time Perhaps doing something a little like this.

Comment 3 Mark Thomas 2014-10-08 14:06:51 UTC
The recently added VersionLoggerListener has been extended to optionally include these environment variables. This feature is enabled by default. This change has been applied to 8.0.x for 8.0.15 onwards. I do not intend to propose this for backport to 7.0.x or 6.0.x.
Comment 4 Violeta Georgieva 2014-10-20 15:21:39 UTC
This is back-ported in 7.0.x and will be available in 7.0.57 onwards.
