Usage:
 check_icmp [options] [-H] host1 host2 hostN

Options:
 -h, --help
    Print detailed help screen
 -V, --version
    Print version information
 --extra-opts=[section][@file]
    Read options from an ini file. See
    https://www.monitoring-plugins.org/doc/extra-opts.html
    for usage and examples.
 -H
    specify a target
 [-4|-6]
    Use IPv4 (default) or IPv6 to communicate with the targets
 -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)
 -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.
