It counts packets and bytes for a each unique (ip, device, macaddress, direction) group.  Only private IPs will be accounted for.\n\nIt can \"resolve\" names using a dnsmasq lease file.\n\nOnly work with IPv4 for now.\n\nThe result of the build is a statically compiled binary embedding the eBPF code.\n\n## Output\n\n```\n# curl -Ss http://localhost:9042/metrics\n# HELP overseer_bytes_total Number of packet seen by overseer in bytes\n# TYPE overseer_bytes_total counter\noverseer_bytes_total{dev=\"overseer\",device_name=\"client2\",direction=\"egress\",ip=\"100.64.42.1\",macaddr=\"de:ad:be:ef:ba:be\"} 98\noverseer_bytes_total{dev=\"overseer\",device_name=\"client2\",direction=\"ingress\",ip=\"100.64.42.1\",macaddr=\"de:ad:be:ef:ba:be\"} 98\n# HELP overseer_packets_total Number of packet seen by overseer in number of packets\n# TYPE overseer_packets_total counter\noverseer_packets_total{dev=\"overseer\",device_name=\"client2\",direction=\"egress\",ip=\"100.64.42.1\",macaddr=\"de:ad:be:ef:ba:be\"} 1\noverseer_packets_total{dev=\"overseer\",device_name=\"client2\",direction=\"ingress\",ip=\"100.64.42.1\",macaddr=\"de:ad:be:ef:ba:be\"} 1\n# HELP promhttp_metric_handler_errors_total Total number of internal errors encountered by the promhttp metric handler.\n# TYPE promhttp_metric_handler_errors_total counter\npromhttp_metric_handler_errors_total{cause=\"encoding\"} 0\npromhttp_metric_handler_errors_total{cause=\"gathering\"} 0\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgregdel%2Foverseer","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgregdel%2Foverseer","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgregdel%2Foverseer/lists"}
