--------------------------------------
Assignee: Robert Munteanu
> Request log format string %D
> ----------------------------
>
> Key: SLING-5344
> URL: https://issues.apache.org/jira/browse/SLING-5344
> Project: Sling
> Issue Type: Bug
> Components: Documentation
> Reporter: Jon Ekdahl
> Assignee: Robert Munteanu
> Priority: Minor
> Labels: requestlogger
>
> 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
> {code}
> %\{end}t \[%R] <\- %s %\{Content-Type}o %Dms
> {code}
> indicating that %D actually produces _milliseconds_, not microseconds. I also
> found the RequestLoggerResponse class \[2] in the Sling code base, where it
> looks like request duration is recorded and reported in milliseconds.
> So is this simply a documentation bug, then? Maybe, maybe not. The Sling
> documentation \[1] also states the Sling follows the Apache httpd log format
> description \[3], where %D means duration in microseconds.
> Either the documentation should be updated to reflect the fact that %D
> produces milliseconds or the implementation should be updated to produce
> microseconds.
