=head1 NAME
http_loadtime - Plugin to graph the HTTP response times of specific pages
=head1 CONFIGURATION
The following environment variables are used by this plugin
target - comma separated URL(s) to fetch (default: "http://localhost/")
requisites - if true also loads images and stylesheets referenced in the page as well, see wget --page-requisites
(default: "false")
cookies - if true saves and loads cookies to and from munin plugin state directory, this can be used for services that
show session statistics to only use one session per http_loadtime uri configuration (default: "false")
example:
[http_loadtime]
env.target http://localhost.de,http://localhost.de/some-site.html
env.requisites true
env.cookies true
env.warning 5
env.critical 30
Do not enable the download of page requisites (env.requisites) for https
sites since wget needs incredible long to perform this on big sites...
