(Adding ECT-June-2015 because this blocks T94578 which is a hard goal for this month)

@Dicortazar: Could you provide an update here with regard to getting data (and potentially also visualization) for the number of active changeset authors per month in Gerrit? (as we have two weeks left in this month)

And realizing that SCR Contributors lists CR users (anybody) and committers (+2), those "reviewers" (+1/+2) also requested in this task might come close enough to committers(+2), but would be nice to compare those numbes at some point.

I still have to work on this task. No advances so far I'm afraid.

@Dicortazar: Thanks for the update. I'm having T94578#1373791 in mind so I'm wondering if any raw CVS data or such could be made available within the next days?

I'm fine waiting for the actual data on July 1st (with the June data complete).

This data is also useful to check what is going on at T103292: Check whether it is true that we have lost 40% of (Git) code contributors in the past 12 months.

Based on this data, some raw numbers that will appear in the scr.html page.

For authors, we're counting all of the unique people sending patchsets:

• "patchset_submitters": [159, 137, 153, 145, 159, 148, 174, 182, 182, 221, 219, 221, 211, 208, 223, 222, 210, 204, 189, 210, 212, 213, 222, 207, 208, 185],

And for reviewers, all of the people adding a +1, -1, +2 or -2 to a patchset:

• "reviewers": [154, 131, 155, 154, 140, 167, 165, 169, 179, 170, 183, 178, 177, 197, 196, 210, 182, 178, 170, 171, 191, 193, 185, 186, 179, 173]

In both cases, the values go from Wed, 01 May 2013, till nowadays.

We're now retrieving those numbers and adding a new chart with this data in scr.html

Viz is ready to go at http://korma.wmflabs.org/browser/scr.html

You'll see that there are two new charts. One of them contains the information patchset_submitters vs. reviewers.

I still have to go through the title of the chart and the trends.

Names were updated and trends added to the loop. This should be updated in the next data retrieval.

Now scr_patchset_submitters-scr_reviewers-scr-metrics-evol- and scr_voted_patchsets-scr_sent_patchsets-scr-metrics-evol- are on the page but empty (not populated yet).
