network-exporter (under development)

It exposes network sent/recv bytes per IP using cgroup ebpf.

❯ curl localhost:9000/metrics

# HELP network_bytes_recv Network Bytes Volume Received
# TYPE network_bytes_recv gauge
network_bytes_recv{source_ip="118.235.14.140"} 3256
# HELP network_bytes_sent Network Bytes Volume Sent
# TYPE network_bytes_sent gauge
network_bytes_sent{destination_ip="118.235.14.140"} 8328
network_bytes_sent{destination_ip="127.0.0.1"} 1410

How to run

$ docker run --rm -d --name exporter -v /sys/fs/cgroup:/sys/fs/cgroup \
  --privileged -p 9000:9000 alicek106/network-exporter:0.0

$ curl localhost:9000/metrics

TODO

• Network metrics per process
• Optimization in main.go (e.g. dequeue keys from bpf map and acculumate again)

Disclaimer

It is not for production usage. It exposes metrics with "ip" label, resulting in high cardinality at prometheus.
