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 volume’s cache, the host port’s statistics are adjusted.
Statistics shown only in XML API output are described in "XML API basetype properties" (page 367).
Syntax
show host-port-statistics
[ports
ports ]
Parameters ports ports
Optional. A comma-separated list of port IDs for which to show information. For port syntax, see
"Command syntax" (page 20). If this parameter is omitted, information is shown for all host ports.
Output Durable ID
Host port ID in the form hostport_
controller-ID-and-port-number.
Bytes per second
Data transfer rate 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
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.
Number of Reads
Number of read operations since these statistics were last reset or since the controller was restarted.
Number of Writes
Number of write operations since these statistics were last reset or since the controller was restarted.
Data Read
Amount of data read since these statistics were last reset or since the controller was restarted.
Data Written
Amount of data written since these statistics were last reset or since the controller was restarted.
Queue Depth
Number of pending I/O operations being serviced.
I/O Resp Time
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
Average response time in microseconds for all read operations, calculated over the interval since
these statistics were last requested or reset.
Write Resp Time
Average response time in microseconds for all write operations, calculated over the interval since
these statistics were last requested or reset.
Reset Time
Date and time, in the format
year-month-day hour : minutes : seconds , when these statistics
were last reset, either by a user or by a controller restart.
