Piwik Barometer Plugin
This is a plugin for the Open Source Web Analytics platform Piwik. If enabled, it will add a two new widgets that you can add to your dashboard.
The widgets will show a Visitor Barometer and a Visit Time Barometer that auto-refresh every 5 seconds. It shows the number of visitors or visit time in a N minute period compared to the maximum number of visitors/average visit time in any N minute period of the last 30 days.
The idea for this plugin came from @muesli who suggested it on #piwik in IRC.
Clone the plugin into the plugins directory of your Piwik installation.
cd plugins/ git clone https://github.com/halfdan/piwik-barometer-plugin.git Barometer
Login as superuser into your Piwik installation and activate the plugin under Settings -> Plugins
You will now find the widget under the Live! section.
