DESCRIPTION
    This module provides parse_netstat().

FUNCTIONS
  parse_netstat(%args) -> [status, msg, result, meta]
    Parse the output of Unix "netstat -np | -anp" command.

    Netstat can be called with "-n" (show raw IP addresses and port numbers
    instead of hostnames or port names) or without. It can be called with
    "-a" (show all listening and non-listening socket) option or without.
    And can be called with "-p" (show PID/program names) or without.

    Arguments ('*' denotes required arguments):

    *   output* => *str*

        Parse the output of Unix "netstat -np | -anp" command.

        Netstat can be called with "-n" (show raw IP addresses and port
        numbers instead of hostnames or port names) or without. It can be
        called with "-a" (show all listening and non-listening socket)
        option or without. And can be called with "-p" (show PID/program
        names) or without.

    *   tcp => *bool* (default: 1)

        Parse the output of Unix "netstat -np | -anp" command.

        Netstat can be called with "-n" (show raw IP addresses and port
        numbers instead of hostnames or port names) or without. It can be
        called with "-a" (show all listening and non-listening socket)
        option or without. And can be called with "-p" (show PID/program
        names) or without.

    *   udp => *bool* (default: 1)

        Parse the output of Unix "netstat -np | -anp" command.

        Netstat can be called with "-n" (show raw IP addresses and port
        numbers instead of hostnames or port names) or without. It can be
        called with "-a" (show all listening and non-listening socket)
        option or without. And can be called with "-p" (show PID/program
        names) or without.

    *   unix => *bool* (default: 1)

        Parse the output of Unix "netstat -np | -anp" command.

        Netstat can be called with "-n" (show raw IP addresses and port

        called with "-a" (show all listening and non-listening socket)
        option or without. And can be called with "-p" (show PID/program
        names) or without.

    Return value:

    Returns an enveloped result (an array). First element (status) is an
    integer containing HTTP status code (200 means OK, 4xx caller error, 5xx
    function error). Second element (msg) is a string containing error
    message, or 'OK' if status is 200. Third element (result) is optional,
    the actual result. Fourth element (meta) is called result metadata and
    is optional, a hash that contains extra information.
