parse_netstat

 parse_netstat(%args) -> [status, msg, result, meta]

Parse the output of "netstat" command.

This program support several flavors of netstat. The default flavor is "linux". Use "--flavor" to select which flavor you want.

Since different flavors provide different fields and same-named fields might contain data in different format, and also not all kinds of possible output from a single flavor are supported, please see the sample parse output for each flavor (in corresponding "Parse::Netstat::*" per-flavor module) you want to use and adjust accordingly.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

• flavor => str (default: "linux")

  Flavor of netstat.

• output* => str

  Output of netstat command.

  This function only parses program's output. You need to invoke "netstat" on your own.

• tcp => bool (default: 1)

  Parse TCP connections.

• udp => bool (default: 1)

  Parse UDP connections.

• unix => bool (default: 1)

  Parse Unix socket connections.

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.
