I have been maintaining Debian Bug Tracking System graphs for a few years, now, though not very actively. They initially were available on people.debian.org/~glandium/bts/, but there have been some recent changes.
A while ago, I started experimenting with brand new graphs on merkel.debian.org/~glandium/bts/, and when merkel was announced to be dying a few months ago, I got in touch with the QA team to know what to do with them, and it was decided we’d put them on qa.debian.org. I unfortunately didn’t follow up much on this and only recently actually worked on the migration, which took place 2 weeks ago.
The result is that the graphs have officially moved to qa.debian.org/data/bts/graphs/, and links on the Package Tracking System have been updated accordingly. There is now also an additional graph tracking all open bugs in the BTS, across all packages:
Today, I added a new feature, allowing to consolidate data for multiple arbitrary packages in a single graph. Such graphs can be generated with the following URL scheme (please don’t over-abuse of it):
As an example, here is a graph for all the bugs on the packages I (co-)maintain:
And here are the bugs affecting Mozilla-related packages:
I guess the next step is to allow per-maintainer consolidation through URLs such as
Update: per-maintainer consolidation has been added.
(Hidden message here: please help triaging these bugs)
