I am not sure of your intent (inbound vs outbound info). If you want to
collect inbound information, you need to monitor syscalls for inbound events
such as accept, accept4, recv, recvfrom. Ping uses ICMP packets and is not
likely to show up in normal syscalls. You might find them by placing audit
rules in the iptables rules.
