Modified Apache processes plugin for Apache SSL

Line 
1#!/usr/bin/perl
2#
3# Plugin to monitor the number of apache-processes running on the
4# machine, and (in addition to a simple process count), separate then
5# into "busy" or "idle" servers.
6#
7# Requirements:
8#       - Needs access to http://localhost/server-status?auto (or modify the
9#         address for another host). See your apache documentation on how to
10#         set up this url in your httpd.conf.
11#
12# Tip: To see if it's already set up correctly, just run this plugin
13# with the parameter "autoconf". If you get a "yes", everything should
14# work like a charm already.
15#
16# Parameters supported:
17#
18#       config
19#       autoconf
20#
21# Configurable variables
22#
23#       urls      - Override default status-url (SSL)
24#       ports     - HTTPS ports numbers (SSL)
