Hi,
I came across what I believe to be a defect in the log format description
[1]. The %D format string is described as "The time taken to serve the
request, in microseconds". However, the default request exit format is
"%\{end}t \[%R] <\- %s %\{Content-Type}o %Dms", indicating that %D actually
produces *milliseconds*, not microseconds. I found the
RequestLoggerResponse class [2] in the Sling code base that suggests that
request duration is at least recorded in milliseconds.
Is this simply a documentation bug, then? Well, maybe not. The Sling
documentation [1] also links to the Apache httpd log format description
[3], where %D means duration in microseconds.
Can somebody confirm that %D produces milliseconds?
Cheers, Jon
