show host-port statistics
Description Shows live performance statistics for each controller host port. For each host port these statistics
quantify I/O operations through the port between a host and a volume. For example, each time a
host writes to a volumes cache, the host ports statistics are adjusted. For host-port performance
statistics, the system samples live data every 15 seconds.
Statistics shown only in API output are described in API basetypes properties.

[ports ports]
Parameters
ports ports
Optional. Specifies a comma-separated list of port IDs for which to show information. For port
syntax, see Command syntax. If this parameter is omitted, information is shown for all host ports.
Output
Durable ID
The host port ID in the format hostport_controller-ID-and-port-number.
Bps
The data transfer rate, in bytes per second, calculated over the interval since these statistics were
last requested or reset. This value will be zero if it has not been requested or reset since a controller
restart.
IOPS
The input/output operations per second, calculated over the interval since these statistics were last
requested or reset. This value will be zero if it has not been requested or reset since a controller
restart.
Reads
The number of read operations since these statistics were last reset or since the controller was
restarted.
Writes
The number of write operations since these statistics were last reset or since the controller was
restarted.
Data Read
The amount of data read since these statistics were last reset or since the controller was restarted.
Data Written
The amount of data written since these statistics were last reset or since the controller was
restarted.
Queue Depth
The number of pending I/O operations being serviced.
I/O Resp Time
The average response time in microseconds for read and write operations, calculated over the
interval since these statistics were last requested or reset.
Read Resp Time
The average response time in microseconds for all read operations, calculated over the interval since
these statistics were last requested or reset.
Write Resp Time
The average response time in microseconds for all write operations, calculated over the interval since
these statistics were last requested or reset.
