Endpoint metrics
Unisphere collects and displays metrics for iSCSI endpoints.
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 iSCSI endpoints.
| Metric | Description |
|---|---|
| Duplicate Acks Received/sec | Duplicate acknowledgments received per second |
| Host IOs/sec | The number of host I/O operations performed each second |
| Packets/sec | Packets per second |
| Reads/sec | The number of read operations performed each second |
| Response Time | The average response time for the reads and writes |
| TCP Retransmits/sec | TCP retransmits per second |
| Throughput | The amount of data being processed through the endpoint |
| Total Read Time | Total time spent performing reads |
| Total Write Time | Total time spent performing writes |
| Writes/sec | The number of write operations performed each second |
