Default: ip (automatic IPv4/IPv6) protocol: icmp # One of icmp, udp. Default: icmp (Requires privileged operation) ``` In each host group the `interval`, `network`, and `protocol` are optional. The interval Duration is in [Go time.ParseDuration()](https://golang.org/pkg/time/#ParseDuration) syntax. NOTE: The config is only read on startup, SIGHUP is not supported (yet). ## Building and running Requires Go >= 1.14 ```console go get github.com/superq/smokeping_prober sudo setcap cap_net_raw=+ep
