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

http://collectl.sourceforge.net/Documentation.html. 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:

http://docs.hp.com/en/A-XCADM-321/A-XCADM-321.pdf

Also see man collectl.
