Thanks for the report, Chukwa!

I added a line that mentions that you started incubation in July 2010.

OK, thanks for the update.

I'd recommend to keep an eye on the activity level, especially to make sure that the mentioned contributors won't have to wait for days or weeks to have their patches reviewed and applied (I'd also recommend mentors to step in such cases if you have spare cycles). For example in the first week of this month chukwa-dev@ saw only a single line of new discussion [1] (that line was a useful contribution, asking for test cases though only 8 days after the patch update) and there have been no commits in almost a month.

Based on that I'm going to categorize Chukwa under low activity and would really love to see activity pick up again in the next few weeks. Otherwise you'll risk being back in the "more activity, or retire" situation you already discussed earlier.
