Using the Groups feature in Lithium Console, you can create a hierarchical tree structure of groups and entities to display your monitoring data however you want.
Groups are essentially free-form folders for any monitored entity in Lithium such as a Device, Object or Metric. Lithium has a built-in structure of Customer, Sites and Devices for arranging the individual monitored devices in your Lithium deployment. Groups allows you to augment this by allow you to create a structure that suits your needs.
