Brocade Application Delivery Controllers
Brocade vADC loadbalancers (previously known as Riverbed SteelApp, and also as Stingray Traffic Manager, and Zeus Traffic Manager) are easy to configure but do not have a distinctive SNMP agent, or system description, and therefore cannot be automatically identified.
Thus, in order to complete the monitoring of a vADC, you must manually set the system.categories field to include the tag "Stingray."
Edit the device in question, and add the tag "Stingray" to the system.categories property:1
Note the existing system.categories may be different from shown, depending on the type of ADC device being added.
