Viewing InfiniBand Statistics
This section describes how to view port statistics for the workstation and
InfiniBand switch, and how to obtain InfiniBand log files.
For more information about configuring, monitoring, and managing the
InfiniBand switch and network, see the documentation provided by the
manufacturer of your InfiniBand switch.
Viewing InfiniBand Information for a Workstation
The InfiniBand driver installed on your workstation provides two commands
that output statistics and information about InfiniBand ports.
To review statistics and information about a port:
1 Log in as root, and type the following commands in a terminal:
cat /proc/iba/<driver_id>/1/port<x>/stats
cat /proc/iba/<driver_id>/1/port<x>/info
where <x> is the port number on the device, and <driver_id> is the
HCA driver ID for your device, for example: mt25218.
