I agree that there's a need for an overview and some sort of

for the statistics and I'll try to see what I can do over the next weeks.
A thumbnail page of graphs would be quite neat also. :-)
I'd like to do that, but I'm a bit afraid of hitting the webserver too
hard. Data is changing constantly, so graphs are created on the fly. I
could probably cache some small versions though and put them on an
overview page.
At some point the ability to annotate the data will become important
(e.g. "We understand the cause of this, it was r1.123 of foo.c, which
was corrected in r1.124. The developer responsible has been shot.")
There's a field in the database for this sort of thing. I just think
it needs some sort of authentication. That'll have to wait a bit.
Sounds great -- it would be nice to be able to have a few annotations
such as "RELENG_7 branchpoint", "7.0 release", that could then appear as
vertical lines in the graphs, and likewise things like "netisr made
default", "libthr becomes default".
Good idea. Thanks!
Finally, in the interests of making your life more complicated, it would
be neat to graph performance across a set of FreeBSD branches overlaid
or vertically offset so you could monitor, say, MySQL performance on
8-CURRENT, 7-STABLE, and 6-STABLE over time.
It's supported by the tools, database and website but currently I just
have 2 (slow) machines to work with at the university. The server is
churning out images for the slave to consume every 2 hours which is an
acceptable sample rate if the intent is to monitor CURRENT development
and provide performance alerts much like the tinderboxes do now. Adding
releases would seriously hurt that rate.
My focus has been strictly on comparing CVS versions because trying to
cover anything else quickly makes the configuration space explode and
the sample rate go down the drain. Lots of interesting comparisons could
be made, however, provided sufficient hardware supplies. Comparing
branches would on the top of the list.
