399869 - Demonstrate a working metrics extension

Status: RESOLVED FIXED

(Toolkit Graveyard :: Data Collection/Metrics, defect)

Description

[Alex Polvi]

bug 393881 proposes a fix for updating the metrics extension to trunk. Once in trunk, we need to confirm that the extension works. To accomplish this, a simple backend will need to be implemented.

The most basic purpose of the backend is to provide a config to the extension. Upon initialization of the extension, it will ping the server for a config. An example config from the server is given here: http://mxr.mozilla.org/seamonkey/source/extensions/metrics/src/nsMetricsConfig.cpp#128

A server response of 200, along with a valid config, should be enough to get the extension to start collecting information. Full details of the server/extension interaction can be found here: http://mxr.mozilla.org/seamonkey/source/extensions/metrics/src/nsMetricsService.cpp#667

Once it is working, a call to about:metrics should display what has been collected since it was last uploaded. Example output from about:metrics is a good enough demonstration that it works as expected.

I got it to work! The config I used can be found here: http://polvi.net/~polvi/metrics/

To test, add "ac_add_options --enable-extensions=metrics" to your mozconfig, then after it is built, change the "metrics.upload.uri" pref to that polvi.net url, and finally set the metrics.upload.enable pref to "true".

I built with a MOZILLA_1_9a8_RELEASE client.mk... it does not, however, work with M8 downloaded from an ftp mirror. Debugging output is showing assertion errors parsing the config, not sure what is up.

From about:metrics :
