I am creating that supposed to ping cloud instances and collect packets data, so to avoid ping and having to open ICMP we decided to use NMAP, but the challenge is that with NMAP I am not sure which option can show packet stats.
I tried $nmap -sn hostname but it yields nothing about packets.
the nmap -sn hostname command should have the information but it uses ICMP afaik. You can try to make it more verbose with some of those options:
nmap -sn -v3 hostname (This is a morre verbose version of the command, you can use v1 or v2 to less verbose responses)

You can try hping3 for a more "ping like" experience:
hping3 -c 4 -V -p 80 -s 5050 -A hostname
