packetforward

Counts number of packets/bytes passing through the eth0 interface of a Node, along with the direction of the packets.

Capabilities​

The packetforward plugin requires the CAP_BPF capability.

Architecture​

packetforward uses an eBPF socket filter program on the host's primary interface to capture packets and generate basic metrics from the captured data.

Code locations​

  • Plugin and eBPF code: pkg/plugin/packetforward/

Metrics​

See metrics for Basic Mode (Advanced modes have identical metrics).

note

adv_forward_count and adv_forward_bytes metrics are NOT associated with packetforward plugin despite similarities in name. These metrics are associated with packetparser.
