 -4, --use-ipv4
    Use IPv4 connection
 -6, --use-ipv6
    Use IPv6 connection
 -H, --hostname=HOST
    host to ping
 -w, --warning=THRESHOLD
    warning threshold pair
 -c, --critical=THRESHOLD
    critical threshold pair
 -p, --packets=INTEGER
    number of ICMP ECHO packets to send (Default: 5)
 -L, --link
    show HTML in the plugin output (obsoleted by urlize)
 -t, --timeout=INTEGER
    Seconds before connection times out (default: 10)

THRESHOLD is <rta>,<pl>% where <rta> is the round trip average travel
time (ms) which triggers a WARNING or CRITICAL state, and <pl> is the
percentage of packet loss to trigger an alarm state.

This plugin uses the ping command to probe the specified host for packet loss
(percentage) and round trip average (milliseconds). It can produce HTML output
linking to a traceroute CGI contributed by Ian Cass. The CGI can be found in
the contrib area of the downloads section at http://www.nagios.org/
