Performance monitoring metrics in the Networks page
The performance metrics selected in the Networks page filter the performance data based on various aspects. The Networks page displays the performance data of networks and network interfaces in tabular and graphical formats. The tables that are listed in this topic provide a list of GUI metrics available at various aggregation levels. These tables also provide the mapping of GUI metrics with the corresponding mmperfmon metrics.
GUI performance metrics that are available in the grid and overview charts
The following table lists the GUI performance metrics that are available in the grid and overview charts.

| Errors Received | netdev_errors_r | Network | Number of data receive errors that are detected by the network interface. | |
| Errors Sent | netdev_errors_s | Network | Number of data sent errors that are detected by the network interface. | |
| RDMA Interfaces tab | Transmitted Data | port_xmit_data | InfiniBand | Total number of data octets, which are divided by 4 (lanes), transmitted through all virtual lanes. |
| Received Data | port_rcv_data | InfiniBand | Total number of data octets, which are divided by 4 (lanes), received on all virtual lanes. | |
| Transmitted Packets | port_xmit_packets | InfiniBand | Total number of packets that are transmitted through all virtual lanes from the port. This might include erroneous packets as well. | |
| Received Packets | port_rcv_packets | InfiniBand | Total number of packets that are received through all virtual lanes. This might include erroneous packets as well. | |
| Received Packets with Errors | port_rcv_errors | InfiniBand | Total number of erroneous packets that are received on the port. These errors include local physical errors an all physical errors, malformed data packet errors, malformed link packet errors, and packets discarded due to buffer overrun. | |
| IP Addresses | No performance data is displayed on this table. |
