[Dart] How to reduce the time window for displayed reports

[Blezek, Daniel J (GE, Research)]

Hi Matt,

  Dart should do what you ask: divide the Continuous track into 24 1
hour segments.  It will take a day or two to get the tracks re-indexed.
You mentioned this isn't working correctly, what's happening instead?

  From what I know of Cleversafe, I think you are on the right course.
Dart was not intended to be a real-time event monitoring system (I
wouldn't even know where to begin writing something like that!), so
writing your own may be the best idea.  Clearly, such a project would be
useful for many people, I would hope you contribute it to the Open
Source world.

Cheers,
-dan

Subject: [Dart] How to reduce the time window for displayed reports

(I'm resending this because I didn't realize I had html-formatted my
previous email post.  This one is supposed to be free of html
formatting.)

My project receives a tremendous number of unique DART reports a day.
We'd like to reduce the time span for displayed reports so that it
doesn't take so long to refresh the Dashboard web pages.  We'd still
like to receive continuous reports, just with smaller amounts of content
per display.

Any suggestions?

I've tried doing something like this in the Project.xml file:

     <TemporalTrack>
       <Name>Continuous</Name>
       <Start>5:00 PM</Start>
       <!-- Duration is in floating point hours -->
       <Duration>1</Duration>
       <DefaultSortBy>timeStamp</DefaultSortBy>
       <DefaultOrder>descending</DefaultOrder>
     </TemporalTrack>

...but do not get the intended results.

I'm not sure if the above will actually show 24 different 1-hour
displays like I hope, or if we need to make 24 different tracks for this
purpose.

The more we grow the more we find we may be pushing the boundaries or
DART's intended use--we find we need much more broader functionality for
our event-reporting server.  We are hoping DART can make due for now
while we construct our own customizations.

Thanks for any help,
-Matt
