[hobbit] "snapshot report" generating wide variety of report times?

[Brodie, Kent]

OK, so the main purpose of the snapshot report is to reflect the color
(status) at that time, and nothing else, right?

If so, then the remainder of the data (procs, cpu stats, etc) are
essentially bogus - as such, should the extra information even be
displayed in a snapshot report?

Doing that would require Hobbit to store - on disk - each and every
status report that arrives, every 5 minutes. This would require a lot
of disk space, add a huge overhead due to all of the I/O activity
needed, and generally result in a significant degradation of Hobbit
performance.

I think that is too high a price to pay for having the right timestamps 
on a snapshot report.

The color is right on the drill down status page. And that's the
primary purpose of the snapshot report.
