# RDF Port metrics

Unisphere collects and displays metrics for SRDF ports.

Within the PM metrics section, V4 is used to denote that the metric is supported only by a storage system (array) running PowerMaxOS 10 (6079). V3 is used to denote that the metric is supported only by a storage system (array) running HYPERMAX OS 5977 or PowerMaxOS 5978. Metrics without the denotation are supported by all storage systems (arrays).

The following table lists all metrics that are available for SRDF ports.

Table 1. RDF port metrics
Metric | Description
--- | ---
% Busy | The percent of time that the port is busy
Avg IO Size (KB) | Calculated value: (HA Kbytes transferred per sec/total I/O operations per sec)
Host lOs/sec | The number of host operations performed each second by the port
Host Throughput | The size of the data transfer from the host in MBs per second
Max Speed | Maximum speed per second
Reads/sec | The number of read operations performed by the port per second
Speed | Speed per second
Throughput Read | The read throughput (MBs) of the port per second
Throughput Written | The write throughput (MBs) of the port per second
Writes/sec | The number of write operations performed by the port per second
