The resource tree is the hierarchical representation of the targets and their resources collected by different probes. This section describes various aspects of the resource tree.
- The resource tree contains nodes for Hosts, Hypervisors, Storage Systems,
and Switches. Each of these nodes contain subnodes. For example, the Hosts node contains
the Linux and Windows subnodes.
- The Storage Systems node includes subnodes related to default and add-on probes. The Hitachi subnode lists the resources collected by the default probes (Hitachi Enterprise Storage and Hitachi NAS). The Hitachi subnode is always displayed even if no license is registered and no data is available in the Analyzer detail view.
Other add-on probe related subnodes such as EMC, HPE, NetApp, and Pure Storage are displayed only when a valid (add-on) license is registered and data is available in the Analyzer detail view.
For example, if the data collected by EMC VMAX probe is available on the Analyzer detail view and valid (add-on) license is registered, then only the EMC > VMAX node is displayed and other nodes, such as EMC > XtremIO, HPE, NetApp, and Pure Storage nodes are not displayed in the tree.Note:- You can check whether add-on license is registered in the Manage > Status > License Information. Click the
icon and then in the Category column, select Third Party Storage. This is a combined capacity (type) license for EMC VMAX, EMC XtremIO, HPE 3PAR, NetApp, and Pure Storage. - If the Third Party Storage license has expired on the Analyzer detail view, the add-on probes related subnodes are no longer displayed. However, you can retrieve processed data using MQL (in Reports > Build feature) and REST API.
- You can check whether add-on license is registered in the Manage > Status > License Information. Click the
- The Hosts, Hypervisors, and Switches nodes are displayed even if no license is registered and no data is available.
- The Storage Systems node includes subnodes related to default and add-on probes. The Hitachi subnode lists the resources collected by the default probes (Hitachi Enterprise Storage and Hitachi NAS). The Hitachi subnode is always displayed even if no license is registered and no data is available in the Analyzer detail view.
- Nodes are displayed as follows to
indicate they are no longer monitored:
: The probe has been deleted or the probe is not monitoring
the target resource. 
: The
Analyzer detail view has not received data from the probe in the last 30 days. You can hide these nodes by using the Hide Inactive Node option.
- The owner of an Hitachi storage system under the Owners node represents the host or application to which the LDEV is provisioned. If an LDEV is presented to multiple hosts, then the owner name is constructed by combining the host group names.
