NNMi node, interface, IP address, and card objects can have capability attributes: See Also
Capabilities can be provided from Network Node Manager i Software Smart Plug-ins (iSPIs) or from integrations with other programs. See the documentation that came with any NNM iSPIs installed in your network environment.
To determine which group of capabilities are available for a specific object, navigate to a view for the object, select an instance of the object. Click the 
Open icon and navigate to the Capabilities tab. The items listed in the table are the Capabilities for that particular object instance. For example, the following illustration shows a Node form with three capability entries.
To pass Capability data within the Full URL, type (or copy and paste) the exact text string from the object form, Capability tab, Unique Key attribute value:
${capabilities[capability.key=<UniqueKeyValue>].capability.key}
Place the Capability into a location in the Full URL that enables the result your want:
Note If the NNMi Web server uses the https protocol, use https instead of http.
http://<serverName>:<portNumber>/<application>?<yourURLparameter1>= ${capabilities[capability.key= <UniqueKey_1>].capability.key}&<yourURLparameter2>= ${capabilities[capability.key= <UniqueKey_2>].capability.key}
Note To extend the NNMi environment with additional applications, you must deploy them into a separate web-server or application-server on the same or different physical server from where the NNMi web-server or application-server is installed. See the Network Node Manager Developer Toolkit for more information.
<serverName> = the appropriate fully-qualified domain name
<portNumber> = the appropriate port number
Note If the Capability that you request in the Full URL does not exist for the selected Node or Interface, the resulting URL passes an empty string.
