Network device-driver statistics by device
The netpmon command can be used to create a report that lists network device-driver statistics by device.
Each row describes the statistics associated with a network device.
- Device
- Name of special file associated with device
- Xmit Pkts/s
- Packets per second transmitted through this device
- Xmit Bytes/s
- Bytes per second transmitted through this device
- Xmit Util
- Busy time for this device, as a percent of total time
- Xmit Qlen
- Number of requests waiting to be transmitted through this device, averaged over time, including any transaction currently being transmitted
- Recv Pkts/s
- Packets per second received through this device
- Recv Bytes/s
- Bytes per second received through this device
- Recv Demux
- Time spent in demux layer as a fraction of total time
In this example, the Xmit QLen is 27.303. Its Recv Bytes/s is 10957295 (10.5 MB/sec), which is close to the wire limit for a 100 Mbps Ethernet. Therefore, in this case, the network is almost saturated.
