Tivoli OMEGAMON XE on z/OS attributes
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 (which are 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
IBM Tivoli 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 levels of Tivoli OMEGAMON XE on z/OS nodes in the Tivoli Enterprise Portal Navigator.

Common Storage attributes |
The Common Storage Area Analyzer (CSA Analyzer) is started.
Note:
The CSA Analyzer is shipped and installed with Tivoli OMEGAMON XE on z/OS.
It is configured as part of the configuration of the OMEGAMON II for MVS component
and is started as a separate started task. |
Coupling facility data collected by the Resources Management
Facility (RMF) Distributed Data Server (DSS) |
- You are running z/OS V1.8 with the following RMF components activated:
- RMF Control Task (RMF)-one instance on each system
- RMF Monitor III Gatherer (RMFGAT)-one instance on each system
- RMF Distributed Data Server (GPMSERVE)-one instance per sysplex
- You have enabled RMF data collection as described in OMEGAMON XE on z/OS: Planning and Configuration Guide.

Cryptographic attributes |
At least one IBM cryptographic coprocessor is installed
and configured and the KM5EXIT3 exit is installed in the Integrated Cryptographic
Service Facility (ICSF).
Note:
The KM5EXIT3 exit is shipped and
installed with Tivoli OMEGAMON XE on z/OS. See Tivoli OMEGAMON XE on z/OS: Configuration Guide for more information. |
DASD MVS workspace and DASD MVS Devices attributes |
The Resource Measurement Facility (RMF) has been started. |
Dynamically-bound PAV aliases |
The system you are monitoring is running z/OS V1.8 or above. |
GRS Ring Systems attributes |
The global resource serialization (GRS) complex is in ring
mode. (If the complex is in star mode, only the name, status, and ring acceleration
of each system are available.) |
HiperDispatch Management and HiperDispatch Logical Processors
attributes. |
HiperDispatch Management mode is On. |
Integrated Facility for Applications (IFA) on CP resource
times at the address space and service class period level |
Either
- z/Series Application Assist Processors are configured on the systems,
or
- Java applications are started using a switch (-Xifa:force)
|
LPAR cluster attributes |
The z/OS system is not running as a guest on z/VM. |
User Response Time attributes |
The End to End (ETE) Response Time collector is started.
Note:
The ETE response time collector is shipped and installed with the Tivoli OMEGAMON XE on z/OS product.
It is configured as part of the configuration of the OMEGAMON II for MVS component
and is started as a separate started task. |
z/OS UNIX System Services attributes |
The address space where the Tivoli OMEGAMON XE on z/OS product is running
has SUPER USER authority. This level of authority is equivalent to root (UID=0). |
Attributes and workspaces
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 sysplex-level predefined workspaces.
Attributes and queries
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 in the Tivoli Enterprise Portal online help.
Attributes and situations
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 in the Tivoli Enterprise Portal online help. For information on the predefined
situations available with this product, see Tivoli OMEGAMON XE on z/OS situations.
