There're several approaches that work pretty well.

1. The official method is to use the ignore_file directive in munin-node.conf. It already contains a couple of regexp patterns that exclude various plugin filenames. Eg. renaming your plugin file to "*.bak" disables it.
2. You can add a command /bin/true directive for the respective plugin to the plugin-conf.d/munin-node file.

There was already a Munin plugin called wget_page at MuninExchange, but it was very limited in respect of configuration/customization. I've rewritten the plugin with a number of supported options, each can be specified globally or on a per URL basis too. The point of the rewrite was to allow per-URL customization of wget's timeout parameter. In the process I've added lots of other options as well.

An in-depth tutorial about Munin: basic setup, alerting, templates, virtual nodes, usage with nagios, creating your own plugins. Imho this is the best documentation available on using email alerting in Munin. It's also listed on the official documentation page of the Munin Wiki. Some further links to visit for configuration tips regarding alering are the munin.conf and faq pages in the Munin Wiki.

Munin is a great open source monitoring program available for a number of platforms. Flash Media Server (FMS) is a streaming server from Adobe aiming mainly at video playback in Flash applications (video players, video conference solutions, etc.). There was already a Munin plugin for FMS (monitoring the number of active connections) at MuninExchange, but the config parameters were hard-coded (in the plugin code) and it lacked documentation on usage and did not match the structure of standard Munin plugins. I've rewritten the plugin to come up for all these shortcomings. The new version of the plugin is available both attached to this post and at MuninExchange.

Munin is a monitoring tool. It can survey a number of computers, keep statistics and generate pretty graphs (static images + html) that you can publish using any kind of a web server. Its emphasis is on plug and play capabilities and ease of use.
I've stumbled on a small, but quite annoying bug in the Multips plugin of munin-node.
