lmt version 3 release

[Jim Garlick]

Version 3 of the Lustre Monitoring Tool (LMT) is now available on gcode:

http://code.google.com/p/lmt/

This is a major release that hopefully will improve LMT usability.
It has been tested with Lustre 1.8.3. A few highlights:

* New ltop that works directly with Cerebro and has an expanded display.
* Auto-configuration of MySQL database (lustre config is determied on the fly)
* Improved error handling and logging (configurable)
* New config file
* Code improvements for maintainability

For those upgrading from Version 2, the LMT schema has not changed,
and the new monitor module is backwards compatible with the Version 2
metric modules. Upgrading consists of:

1. Setting up the new /etc/lmt/lmt.conf config file on the LMT server
2. Updating the lmt-server package on the LMT server and restarting cerebrod
3. Updating the lmt-server-agent package on the Lustre servers and restarting
cerebrod

Please refer to the Installation wiki page on the above gcode site,
and direct any issues to lmt-d...@googlegroups.com and/or
the LMT gcode issue tracker.

LMT 3.1.1 is available for download. This is primarily a bugfix
release
but also includes preliminary support for Lustre version 2.

The Lustre version 2 support was added by Mike MacDonald of Whamcloud.

Thanks to everyone who has tried lmt3 so far, and for taking the time
to document bugs via the google code issues tab.
