  Contains several perl scripts required by CollectionJS:

  • getHosts.cgi - returns a JSON object containing available hosts and plugins. In the example index.html, the script is used to populate the dropdown menus.
  • getPlugins.cgi - expects as parameters a hostname and a plugin, and it returns a JSON array with available charts, containing information such as plugin_instance, type, and type_instance
  • getChart.cgi - based on collection3's graph.cgi, it returns the data required for highcharts in JSON format.

• etc
