Use TALES syntax to retrieve values and call methods on Resource
Manager objects. Several areas accept TALES syntax; these include:
Command templates
User commands
Notifications
zLinks
Commands (those associated with devices and those associated with
events) can use TALES expressions to incorporate data from the related
devices or events. TALES is a syntax for specifying expressions that let
you access the attributes of certain objects, such as a device or an
event.
Depending on context, you may have access to a device, an event, or
both. Following is a list of the attributes and methods you may want to
use on device and event objects. The syntax for accessing device
attributes and methods is ${dev/attributename}. For example, to get
the manageIp of a device you would use ${dev/manageIp}. For events,
the syntax is ${evt/attributename}.
A command to ping a device might look like this. (The ${..} is a TALES
expression to get the manageIp value for the device.)
