parse_netstat¶

Usage:

 parse_netstat(%args) -> [$status_code, $reason, $payload, \%result_meta]

Parse the output of "netstat" command.

This utility 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 utility 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.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)
