#!/usr/bin/perl # # Plugin to monitor the number of apache-processes running on the # machine, and (in addition to a simple process count), separate then # into "busy" or "idle" servers. # # Requirements: # - Needs access to http://localhost/server-status?auto (or modify the # address for another host). See your apache documentation on how to # set up this url in your httpd.conf. # - also requires libcrypt-ssleay-perl # # Tip: To see if it's already set up correctly, just run this plugin # with the parameter "autoconf". If you get a "yes", everything should # work like a charm already. # # Parameters supported: # # config # autoconf # # Configurable variables # # urls - Override default status-url (SSL) # ports - HTTPS ports numbers (SSL) # # $Log$ # Revision 1.8 2006/03/07 20:30:00 fra519 # modified for Apache SSL Server. # # Revision 1.7.2.1 2005/02/24 17:51:08 jimmyo # modified graph_args of generic/apache_processes, to work around an rrdtool bug (Deb#296528). # # Revision 1.7 2004/05/20 13:57:11 jimmyo # Set categories to some of the plugins. # # Revision 1.6 2004/05/14 21:16:46 jimmyo # "Upped" som plugins from contrib/manual to auto. # # Revision 1.5 2004/04/27 08:46:57 jimmyo # Fixed broken autoconf in apache-* plugins (Deb#236144). # # Revision 1.4 2004/02/03 17:17:25 jimmyo # Generic/apache-plugins have been modified to properly to report the correct autoconf value.
