     -H
        specify a target
     -w
        warning threshold (currently 200.000ms,40%)
     -c
        critical threshold (currently 500.000ms,80%)
     -s
        specify a source IP address or device name
     -n
        number of packets to send (currently 5)
     -p
        number of packets to send (currently 5)
     -i
        max packet interval (currently 80.000ms)
     -I
        max target interval (currently 0.000ms)
     -m
        number of alive hosts required for success
     -l
        TTL on outgoing packets (currently 0)
     -t
        timeout value (seconds, currently  10)
     -b
        Number of icmp data bytes to send
        Packet size will be data bytes + icmp header (currently 68 + 8)
     -v
        verbose

    Notes:
     The -H switch is optional. Naming a host (or several) to check is not.

     Threshold format for -w and -c is 200.25,60% for 200.25 msec RTA and 60%
     packet loss.  The default values should work well for most users.
     You can specify different RTA factors using the standardized abbreviations
     us (microseconds), ms (milliseconds, default) or just plain s for seconds.

     The -v switch can be specified several times for increased verbosity.
