3 iba_top Fabric Performance
Monitor
Introduction
iba_top is a command line tool which displays performance, congestion, and
error information about a fabric. Fabric information is divided into two areas -
performance and error statistics, which are the main starting points for analyzing
fabric traffic. Performance (bandwidth utilization) can identify over-utilized areas
(bottle necks) and under-utilized areas (potentially misconfigured); errors can
identify problems in fabric hardware or configuration, as well as congestion and
other performance situations.
