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