[Lustre-discuss] 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-discuss at googlegroups.com and/or
the LMT gcode issue tracker.
