Interface metrics missing with CRA-vSR

[chdxD1]

In CRA-FRR we enabled interface metrics by including prometheus-node-exporter. However with CRA-vSR no such mechanism exist as of today.

Metrics that should be included per interface:

• node_network_speed_bytes

• node_network_receive_packets_total

• node_network_receive_bytes_total

• node_network_receive_drop_total

• node_network_receive_errs_total

• node_network_transmit_packets_total

• node_network_transmit_bytes_total

• node_network_transmit_drop_total

• node_network_transmit_errs_total

• node_network_up

• node_network_carrier_changes_total

• node_network_carrier_down_changes_total

• node_network_carrier_up_changes_total

The metrics do not need to have the same name as the ones from node-exporter. Something like nwop_vsr_intf_speed_bytes is also fine.

If device is hardware interface (and possible): Include SFP metrics (optical levels, transceiver info etc) from ethtool -m <intf>, especially laser output and receive power for each lane (if multiple lanes are present, e.g. for QSFP links).

Example ethtool -m <intf> output:
