Gotcha.

How about sending them to me and Ethan?

Agreed; we aren't super-fond of the current web page, either. Do you
guys want to have a teleconf to go over the current status of MTT,
where you want it to go, etc.? I consider IU's input here quite
important, since you're the ones pushing the boundaries, flexing
MTT's muscles, etc.

Ok.

We created another ticket yesterday to make a new MTT Reporter (our
internal plugins) that duplicates this output format. It actually
shouldn't be that hard -- we don't have to do parsing to get the
numbers that you're reporting; we have access to the actual data. So
it's mostly caching the data, calculating the totals that you're
calculating, and printing in your output format.

Ethan has some other short tasks to do before he gets to this, but
its near the top of the priority list. You can see the current
workflow on the wiki (this is a living document; it keeps changing as
requirements, etc. change):

We have the summary.php page, but I personally have never found it
too useful. :-)

We're getting towards a full revamp of reporter.php (got some other
tasks to complete first, but we're definitely starting to think about
it) -- got any ideas / input? Our "haven't thought about it much
yet" idea is to be more menu/Q-A driven with a few common queries
easily available (rather than a huge, complicated single screen).

For the moment, we don't have the dynamic capability for you to login
to the web page, create a report, and say "mail this to me nightly".
However, Ethan can make up custom reports on the server quite easily
-- if you want some IU-specific reports, just file a ticket and Ethan
can Make It So.

That's what we intended for the mails that are coming today, but it
seemed to not be sufficient -- we ended up with 4 nightly mails, one
for each relevant phase failures and a 4th for showing stderr of mpi
installs.

At the moment, I've been manually examining the mails every day and
firing off e-mails to those responsible. However, due to travel last
week and this week, I've gotten quite behind. :-(

True. I don't know the proper answer to this, either -- I know the
"Jeff look at e-mail" solution doesn't scale well.

Awesome.

I would like to schedule some phone time with you guys and Ethan and
me to talk about what's working, what's not working, etc. One
obvious question I have is: is the INI config file format suitable?
Do we need to do something more complex that would allow
consolidation of your various configurations? ...etc.
