Jon Ekdahl created SLING-5344:
---------------------------------
Summary: 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
Priority: Minor
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.
