downtime

Measures downtime by detecting the start and end of ICMP request timeouts (like ping -D -W 0.05 -i 0.1 <target>).

The tool needs sudo and the net raw capability to handle raw ICMP pakets:

sudo setcap cap_net_raw+ep <path to binary>

Quick start

1. install: go install github.com/RaphaelPour/downtime/cmd/downtime
2. set capability: sudo setcap cap_net_raw+ep <path to binary>
3. run: sudo downtime --target <target>

example:

   start: 2023-08-16 10:12:47.197488336 +0200 CEST m=+20.651438246
     end: 2023-08-16 10:13:06.331099665 +0200 CEST m=+39.785050063
duration: 19.133611817s
