4 Real-Time Fabric Monitor
Real-time Fabric Monitor Overview
The Real-time Fabric Monitor (RFM) is a TUI based user interactive application
that provides real-time fabric monitoring support. It must be run on a host
connected to the InfiniBand fabric with FastFabric installed. To use the
Performance view of RFM the QLogic Fabric Manager must be installed.
The RFM obtains all its data in an InfiniBand Trade Association (IBTA)-compliant
manner. Therefore, it will interoperate with both QLogic and 3rd party InfiniBand
components, provided those components are IBTA compliant and implement the
IBTA optional features required by the RFM
The RFM requires that the subnet manager implement all the IBTA SA queries
defined in the standard (such as SM Info records, Link Records, Trace Routes,
Port Records, Node Records, etc). As such, it is recommended that the QLogic
Fabric Manager version 4.0 or later be used. The RFM requires all end nodes to
implement the PMA PortCounters (IBTA mandatory counters). Also any end
nodes which report support of a IBTA device management agent must implement
the IOU Info, IOC Profile and Service Entry queries as outlined in the IBTA 1.1
standard.
The RFM takes advantage of these interfaces to obtain extensive information
about the fabric from the subnet manager and the end nodes. Using this
information, the RFM is able to cross reference it and produce analysis greatly
beyond what any single subnet manager request could provide. As such, it
exceeds the capabilities previously available in tools such as iba_saquery and
fabric_info.
The RFM displays the information in a user-friendly TUI based user interface. The
RFM user interface enables users to analyze the information, using interactive
requests from the user.
The RFM obtains up to date information about the fabric by performing a
discovery of the fabric when it is first started. Each discovery will take a few
seconds (or less, depending on the size of the fabric) to obtain all the fabric data.
The RFM is started by entering the following command at a command prompt.
