Attributes are characteristics or properties of the logical and physical objects monitored by Tivoli OMEGAMON XE on z/OS (for example, the amount of allocated virtual storage). Related attributes are organized into groups (referred to as tables in the context of historical data collection).
These attributes are used to define the queries that collect the information displayed in tables and charts in the Tivoli OMEGAMON XE on z/OS workspaces and to create situations that trigger alerts and automated actions in response to specified conditions.
You can see an overview of an attribute group, or get detailed information about a specific attribute, by selecting its name under Attributes, in the OMEGAMON XE on z/OS section of the Contents tab. In the listing on the Contents tab, Attribute groups are divided into two types, system and sysplex, corresponding to the two Tivoli OMEGAMON XE on z/OS nodes in the CandleNet Portal Navigator.

For information on installing the KM5EXIT3 and required started tasks, see Configuring IBM Tivoli OMEGAMON XE on z/OS.
Most workspaces display data for a single attribute group. For a tabular representation of the relationships between the predefined workspaces and the attribute groups, see Attribute groups used by the system-level predefined workspaces or Attribute groups used by the sysplex-level predefined workspaces.
Chart and table views use queries to request attribute values from the Tivoli OMEGAMON XE on z/OS agent for display. You can modify predefined views by editing the queries on which they are based, or design custom views by creating your own queries that collect data for just those attributes you specify.
For information on creating custom queries, see Custom Queries Overview and related topics.
You can use the Tivoli OMEGAMON XE on z/OS attributes to create your own situations to monitor or troubleshoot the performance of your systems, analyze their status, and alert you to problems.
For information on creating situations, see Situations and Events Overview and related topics. For information on the predefined situations available with this product, see Tivoli OMEGAMON XE on z/OS Situations.
