5.8 Lustre Performance Monitoring
You can monitor the performance of Lustre clients, Object Storage Servers, and the MetaData
Server with the open source tool collectl. Not only can collectl report a variety of the more
common system performance data such as CPU, disk, and network traffic, it also supports
reporting of both Lustre and InfiniBand statistics. Read/write performance counters can be
reported in terms of both bytes-per-second and operations-per-second.
For more information about the collectl utility, see
. Choose the Getting Started section for
information specific to Lustre.
Additional information about using collectl is also included in the HP XC System Software
Administration Guide Version 3.2.1 in section 7.7 on the HP website at:
Also see man collectl.
