Fiber Channel driver statistics
The following table displays the supported field names for the Fiber Channel
driver statistics. These fields are specific to the Fiber Channel device instances. The syntax of
the Vue statement is __stat.io.adapter.fcs[0...n]->fieldname. The following statistics are
accessible only in asynchronous mode.
| Vue script field name | Data type | Description |
|---|---|---|
| secs_since_last_reset | unsigned long long | Time in seconds since last reset |
| tx_frames | unsigned long long | Number of frames transmitted |
| tx_words | unsigned long long | Fibre channel kbytes transmitted |
| rx_frames | unsigned long long | Number of frames received |
| rx_words | unsigned long long | Fibre channel kbytes received |
| lip_count | unsigned long long | Count of Loop Initiation Primitive (LIP) events on Fibre Channel Arbitrated Loop (FC-AL) |
| nos_count | unsigned long long | Count of No Operating System (NOS) events |
| error_frames | unsigned long long | Number of frames received with the cyclic redundancy check (CRC) error or discard frames. Each adapter has different field assigning this field. |

| ctrl_reqs | unsigned long long | Control requests |
| in_bytes | unsigned long long | Input bytes |
| out_bytes | unsigned long long | Output bytes |
| no_dma_resource_count | unsigned long long | Count of DMA failures due to no DMA resources available |
| no_adap_elems_count | unsigned long long | Count of failure to allocate an adapter command element due to no more command element available |
