[jira] [Created] (SLING-2516) Reuqest Performance Analysis helper
Felix Meschberger created SLING-2516:
----------------------------------------
Summary: Reuqest Performance Analysis helper
Key: SLING-2516
URL: https://issues.apache.org/jira/browse/SLING-2516
Project: Sling
Issue Type: New Feature
Components: Extensions
Reporter: Felix Meschberger
Assignee: Felix Meschberger
To measure overall request performance, Sling has a RequestProgressTracker where each request is tracking progress as a request is processed. Normally this RequestProgressTracker is just collected but other than being presented in the "Recent Requests" page of the web console not further used.
To track down generic bottle necks and processing peaks while doing load tests on a Sling system, it would be usefull if the RequestProgressTracker data could be dumped into a file which can later be displayed and analysed.

---------------------------------------
FYI - the RequestProgresssTracker data can already be dumped to a file by setting the log level on org.apache.sling.engine.impl.debug.RequestProgressTrackerLogFilter to DEBUG.

---------------------------------------
Understood and I definitely can see how this adds new capability. I just wanted to ensure that anyone stumbling onto this issue can see that there's a way to get the raw data.

RIght. This tool just generates a nice file and comes with another tool to render that file even more nicely. Much easier to particularly in a setup where lots of requests are hammered at the Sling application, say in a performance test.

[jira] [Commented] (SLING-2516) Reuqest Performance Analysis helper

Felix Meschberger commented on SLING-2516:
------------------------------------------
Committed a first shot of such a tool in Rev. 1352777
The maven project is both a bundle and a standalone Java Application. When deployed as a bundle in Sling's OSGi framework it registers as a Sling request level filter and dumps information for requests to a file:
* one line with request start time stamp, processing time in ms, request URL, method, response content type and status
* The complete RequestProgressTracker data
When used as a standalone java application (à la java -jar ...) it takes the name of a file produced by said filter and opens a window with the list of requests collected in the file. This list can be sorted by any of the columns -- for performance analysis sorting by the request processing time is very helpful. When clicking on a request another window is opened showing the RequestProgressTracker data in three columns: time offset since start of request, time delta since last entry, entry message. These helps nicely find hotspots in request processing.
