On my LiNUX RedHat 7.3, I've got : PING(8) System Manager's Manual: iputils PING(8) NAME ping, ping6 - send ICMP ECHO_REQUEST to network hosts SYNOPSIS ping [ -LRUbdfnqrvVaA] [ -c count] [ -i interval] [ -l preload] [ -p pattern] [ -s packetsize] [ -t ttl] [ -w deadline] [ -F flowlabel] [ -I interface] [ -M hint] [ -Q tos] [ -S sndbuf] [ -T timestamp option] [ hop ...] destination So the -s option should be helpfull, you just have to add this option to your nagios/etc/checkcommands.cfg file.
