• Go build

> git clone https://github.com/thc2cat/go-icmp-status 
> cd go-icmp-status 
> go mod tidy 
> go build

• Options

• Yellow for a host up but loosing packets during interval, [Received/Sent/Percent] indicate x received packet for y sent packets during interval. Percent indicate percentage of received packets since start.
