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 355). 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. 244
