A resource is an entity in your network for which the Brocade SAN Analytics Management Pack for
VMware vCenter Operations Management Suite collects data. A resource can be a fabric, switch,
host, storage, virtual machine (VM), or a container that holds other resources (such as,
applications).

Health Tree

The health tree displays the relationship between various resources using a parent-child
relationship. The Fabric resource is the parent for all switches that belong to the fabric and the
Switch resource is the parent for the F-ports connected to end devices. E-ports on the switch
display as a metric group or resource group on the Switch resource. The End Devices (such as
Hosts, Virtual Machines (VM), and Storage devices) are parents of the Fabric resource. The end
device data obtained from the Brocade Network Advisor data source is correlated with the Hosts
and VMs known to the vCenter registered with vCenter Operations Manager. If the VM has a path to
a Storage known to the vCenter and collected from the Brocade Network Advisor server, the
Storage resource is displayed as a parent of the Fabric.

For FCR deployment, devices display as a storage device in the Initiator connected fabric link. Note
that phantom switches do not display in the interface.

For FCIP deployment, Ve and Vex ports and tunnels do not display in the interface.

For Access Gateway (AG) deployment, AG switches display as a resource group. In the collection
data, Switch Mode displays as Access Gateway and the Domain Id field is empty. If you are
collecting data from Brocade Network Advisor 12.2 or later, data is collected for the AG ports. If you
are collecting data from Brocade Network Advisor 12.1.X or earlier, data is not collected for AG
ports and the value displays as zero.
