The idea is in my head for quite some time, I am throwing it out.
Telemetry is some sequence of values along time line. It's good for long
term trend. Sometimes we want to see detailed information, for example,
the dependency relationship between different modules (like the chart
Christoph once generated), which can not be expressed by a single
value. HackyReport supports chart drill down. When you click on a point
in a chart, you will be directed to a new URL. If the reduction function
can include the url information, we can have a telemetry chart that can
be drilled down.
Note that this is only a preliminary idea. The consequences to the
telemetry language and the implementation details are still not thought
out well.
Cheers,

Hey Christoph,
I think a dependency reducer would be interesting. But, I'm not sure
about
the exact calculations of the reducer. For example, I'm not sure how to
interpret the average dependencies. I suppose the best thing to do is to
give it a try; besides it shouldn't take that much development effort.
One calculation that might be interesting is something similar to the
issue
reducer that calculates the delta of outgoing or incoming
dependencies. Or
maybe not, because plotting the sum of incoming/outgoing overtime should
allow us to see the changes. Anyway, I think the best thing to do, is to
use a GQM type strategy in determining what reducers would be most useful
in answering a Question.
BTW, I've been wanting to add a Dependency entry into the
DailyProjectDetailAnalysis for a while now
<http://hackydev.ics.hawaii.edu:8080/browse/HACK-251>, but wasn't quite
sure what data it should provide. For example, is the sum of all
dependencies actually interesting?
thanks, aaron

Hi guys!
What do you think about having a telemtry reduction function which can
plot stuff like 'average dependencies per class/method/package', 'sum
of ingoing' , 'sum of outgoing' or 'sum of all dependencies',
filtered by workspaces?
Would this be useful?
Cheers,
Christoph
