Performance and Error Statistics for Each Port Group
Fabric performance and error statistics are presented based on four groupings of
ports: All (all ports in the fabric), HCAs, TCAs and SWs. These groups provide a
natural subdivision of the ports in a fabric for analysis. For more information about
Groups and the operation of the PM, refer to the QLogic Fabric Manager User
Guide.
For each port group, average, minimum and maximum MBps (megabytes per
second), and KPps (kilopackets per second) are shown, as well as a status
indicator for each of five error categories.
Performance Statistics
Performance statistics for each port group are further divided into up to three
subgroups - Internal, Send and Receive - based on whether a port's neighbor port
is in its group. If a port's neighbor port is in its group, all performance statistics are
contained in the Internal subgroup. If a port's neighbor is not in its group, statistics
for data leaving the port (group) are contained in the Send subgroup and statistics
for data entering the port are contained in the Receive subgroup.
All Group
In the All group all ports are Internal since, by definition, the neighbor port must be
in the All group.
HCAs and TCAs Groups
In the HCAs and TCAs groups all neighbor ports are outside the group so
statistics are contained in the Send and Receive subgroups.
SWs group
In the SWs group neighbor ports are either outside the group (HCA or TCA) or
inside the group (another switch) so statistics are contained in all three subgroups.
Error Categories
The five error categories are:
Integ — Integrity
Congst — Congestion
SmaCong — SMA Congestion
Secure — Security
Routing — Routing
These error categories are each based on one or more port error counters. Each
error category’s status indicator is shown at one of five values/colors:
minimum/green, Low/blue, Moderate/cyan, Warning/yellow or OVER/red based
on the error value as compared to a threshold value.
