Hi All,
We have a new and improved version of LMT released
on Sourceforge.  For those who have never used it, LMT is the Lustre
Monitoring Tool developed at LLNL.  It provides realtime monitoring of a
Lustre filesystem (or multiple filesystems).  It also graphs data over time
for a set of attributes specified by the user.  Please feel free to try it
out.

Below are the release notes.
(please forgive this if it is a repost as it looks like lustre-discuss
may have finally come back up)

Release Notes for LMT 2.6.0                                  07 Apr 2008
========================================================================

* This version of LMT 2 has been tested to work properly with Lustre 1.6.x
  It is no longer necessary to keep the old lustre *.xml configuration and
  there are no more xwatch-lustre.conf or lmt.conf files to set up.

* LMT now uses Cerebro to transport the data collected from the Lustre
  filesystem being monitored. For more info see:
  http://sourceforge.net/projects/cerebro

* Building the rpms requires ibm-java since this is what we use in Chaos 4.
  This can be changed in the specfile to require Sun Java if that is
  preferred (the main issue is that we need a full fledged JVM that
  supports swing).

* There is now a dependency on mysql to store the collected data. Since the
  resolution of the collection is ~5 seconds this can quickly consume a lot
  of space.  The clients and servers are completely decoupled.

* Please refer to the documentation for instructions on how to install and
  configure LMT 2.
