check ping explanation required

[shadih rahman]

        Nagios uses check_ping for the host check of most hosts.

        The check is configured to send only one ping.

        So if Nagios receives a response, it is 0% packet loss.

        If no response, it is 100% packet loss.


# 'check-host-alive' command definition
define command{
        command_name    check-host-alive
        command_line    $USER1$/check_ping -H $HOSTADDRESS$ t 45 -4 -w
3000.0,100% -c 3000.0,100% -p 1
        }




        Yet, Nagios reports:



                ping at bway2852-3-1.net.columbia.edu:2009-06-30 23:24:33:PING
OK - Packet loss = 85%, RTA = 47.06 ms



        How is it possible for Nagios to lose 85% of one ping?
