Hi all The RequestProgressTrackerLogFilter allows logging the information collected by the RequestProgressTracker at debug level. Since this can amount to several undred lines logged per request, this may be prohibiitive on a busy production system.
I propose to reduce the size of the log file by doing the following: 1. changing the log format to include less redundant data 2. allow filtering by request duration 3. allow filtering by request extension(s) Regarding point 1, currently each "message" of the RPT is logged with a debug statement. The proposed "compact" format only logs one debug statement. This spans multiple lines, space indented, similar to how stack-traces are logged. See an example of both at the bottom of this message. I created SLING-4114 [0] with a patch attached that implements these changes. Note that I made some additions to the RequestProgressTracker API. These should be compatible for consumers, so I think they should not do any harm. Could someone please take a look at the patch, and if everything is ok, commit it? Thank you.
