You can view the LUN metrics only when the ACOS (AVE) cluster provides the block storage service for other clients and the cluster has been set providing block storage services for external clients in AOC.
The ACOS (AVE) cluster only provides fine-grained monitoring metrics for LUNs.
| Name | Unit | Description |
|---|---|---|
| IOPS - read | IOPS | The read IOPS of the LUN. |
| IOPS - write | IOPS | The write IOPS of the LUN. |
| IOPS - overall | IOPS | The total read and write IOPS of the LUN. |
| IOPS - read and write | IOPS | If you select this metric, both read and write IOPS will be displayed in the chart. |
| I/O bandwidth - read | Bps | The read operation bandwidth of the LUN. |
| I/O bandwidth - write | Bps | The write operation bandwidth of the LUN. |
| I/O bandwidth - overall | Bps | The total bandwidth of read and write operations of the LUN. |
| I/O bandwidth - read and write | Bps | If you select this metric, both the bandwidth of read operations and the bandwidth of write operations are displayed in the chart. |
| I/O average latency - read | ns, ms, s | The average latency of read operations on the LUN. |
| I/O average latency - write | ns, ms, s | The average latency of write operations on the LUN. |
| I/O average latency - overall | ns, ms, s | Average read operation latency * Read operation ratio + Average write operation latency * Write operation ratio. |
| I/O average latency - read and write | ns, ms, s | If you select this metric, both the average latency of read operations and the average latency of write operations are displayed in the chart. |
| I/O average block size - read | B, MiB, GiB ... | The average size of the data blocks read. |
| I/O average block size - write | B, MiB, GiB ... | The average size of data blocks written. |
| I/O average block size - overall | B, MiB, GiB ... | Average read block size * Read operation ratio + Average write block size * Write operation ratio. |
| I/O average block size - read and write | B, MiB, GiB ... | If you select this metric, both the average size of data blocks read and the average size of data blocks written will be displayed in the chart. |
