The Lustre Monitoring Tool (LMT) monitors Lustre File System servers (MDT, OST, and LNET routers). It collects data using the Cerebro monitoring system and optionally stores it in a MySQL or MariaDB database. A text client is provided which displays real time data from Cerebro, and historical data saved to a file.
LMT 3.2.6 supports Lustre 2.5.X through 2.15.X. It provides support for multiple MDTs in the same filesystem (DNE1 and DNE2).
LMT3 added the following features versus LMT2:
- New ltop that works directly with Cerebro and has an expanded display.
- Auto-configuration of the database (lustre config is determined on the fly)
- Improved error handling and logging (configurable)
- New config file
- Code improvements for maintainability
