Statistics 3 I/O performance Use the fcpim -ioperf command to display I/O performance in terms of IOPs and throughput for physical ports and I-T nexus (ITN) sessions for a logical port. Use the command with a physical port range or with a specific physical port ID. Using port range The following command displays IOPs and throughput for a range of physical ports. --ioperf [-l | -r] [-c count] [-i interval] where: port_range -l -r -c -i This is the adapter number/port number-adapter number/port number. For example, the range 1/0-2/0, includes adapter 1, port 0 and adapter 2, port 0. Displays information about all logical ports in all physical ports in the range. Displays information about all ITM sessions in all physical ports in the range. This includes all logical and remote port information. Count. The number of iterations of the display. The default behavior is to continuously refresh. Use Ctrl-C to terminate. Interval. The sampling delay in seconds [default is 1 second]. The sampling interval can be between 1 and 10. Using specific port ID The following command displays IOPs and throughput for a specific physical port ID. --ioperf [-l ] [-r ] [-c count] [-i interval] where: port_id -l pwwn -r pwwn -c -i ID of the port for which you want to display statistics. This could be the PWWN, port hardware path, or user-specified port name. This could also be the adapter-index/port-index. For example, to specify adapter 1, port 1, you would use 1/1 as the port identification. Displays information about a specific logical port for the physical port. To display data about all logical ports, use -l without a PWWN. Displays information at I-T nexus between a given logical port and specified remote port for the physical port. To display data about all remote ports, use -r without a PWWN. Count. The number of iterations of the display. The default behavior is to continuously refresh. Use Ctrl-C to terminate. Interval. The sampling delay in seconds [default is 1 second]. The sampling interval can be between 1 and 10. Brocade Adapters Troubleshooting Guide 79 53-1002145-01

I/O performance
Use the
fcpim -ioperf
command to display I/O performance in terms of IOPs and throughput for
physical ports and I-T nexus (ITN) sessions for a logical port. Use the command with a physical port
range or with a specific physical port ID.
Using port range
The following command displays IOPs and throughput for a range of physical ports.
--ioperf <port_range> [-l | -r] [-c count] [-i interval]
where:
port_range
This is the adapter number/port number-adapter number/port number. For
example, the range 1/0-2/0, includes adapter 1, port 0 and adapter 2, port
0.
-l
Displays information about all logical ports in all physical ports in the range.
-r
Displays information about all ITM sessions in all physical ports in the range.
This includes all logical and remote port information.
-c
Count. The number of iterations of the display. The default behavior is to
continuously refresh. Use Ctrl-C to terminate.
-i
Interval. The sampling delay in seconds [default is 1 second]. The sampling
interval can be between 1 and 10.
Using specific port ID
The following command displays IOPs and throughput for a specific physical port ID.
--ioperf <port_ID> <port_id> [-l <lpwwn>] [-r <rpwwn>] [-c count] [-i interval]
where:
port_id
ID of the port for which you want to display statistics. This could be the
PWWN, port hardware path, or user-specified port name. This could also be
the adapter-index/port-index. For example, to specify adapter 1, port 1, you
would use 1/1 as the port identification.
-l pwwn
Displays information about a specific logical port for the physical port. To
display data about all logical ports, use -l without a PWWN.
-r pwwn
Displays information at I-T nexus between a given logical port and specified
remote port for the physical port. To display data about all remote ports, use
-r without a PWWN.
-c
Count. The number of iterations of the display. The default behavior is to
continuously refresh. Use Ctrl-C to terminate.
-i
Interval. The sampling delay in seconds [default is 1 second]. The sampling
interval can be between 1 and 10.
