Are there any screenshots/FAQs?
I looked at the package, and the depandancy list is long.
As most of my work is remote, does the GUI run remotely over an SSH tunnel?
Are there any similar console/text-based utilities w/ a shorter
dependency list and lighter weight for remote access?
Thanks,

Hi Chris,
I think Herb is reporting for jury duty today so I'll speak up and let him
follow up later if I missed anything.
There are text clients (ltop and lstat). I haven't tried running
the GUI remotely and tunneling the X session, or running the client
locally and tunneling mysql protocol, bu
Hi Jim,
Out of curiosity (and bear with me if this is a stupid question), do you
know if anyone's integrated LMT with Ganglia? The clusters we have that use
Lustre are all ROCKS-based, which uses Ganglia for monitoring ... I'm not
familiar with Cerebro, so I'm not sure how you're using it, but it
Hi Jim,
Hmmm, good to know ... does LMT support shell call-outs? If so, it would be
easy enough to have it populate a Ganglia receptor using gmetric (using the
older pre-3.1.x framework) ... not sure about recording from Ganglia to
mysql, although it would record historical data using rrdtool.

Hi Klaus,
Nobody's done that yet that I know of, but it would seem doable.
Cerebro is similar to ganglia in that it uses multicast with
listeners and talkers. You would need machinery to get lustre proc
values into ganglia on the lustre servers (the talkers), and then from
ganglia to the mysql
If the goal is to get lustre data into ganglia and use existing
mechanisms to look at the data, LMT is probably not the right path.
But if you wanted to set up LMT and just replace the back-end data
collection mechanism, that is probably doable. I'm afraid my
knowledge of ganglia falls short he

Klaus,
As the LMT backend is currently a set of Cerebro modules, it does not have
to ability to support callouts on its own. Cerebro supports the callouts
that you would be looking for with cerebro-stat.
As Jim mentioned you need the listener (monitor module), to populate the
mysql database if yo

I just replaced the older LMT screenshots that were on sourceforge with a
few new ones. The filesystem view looks largely the same as it did in the
older versions (although now there is also on OSS panel in addition to the
OST panel).
There are also now plot w
