Attributes
Attributes are characteristics or properties of the logical and
physical objects monitored by 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 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 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.

Prerequisites
Some attributes display data only if specific conditions are met:
Data is available
for |
Only if |
4 Hour MSUs attribute in the System CPU Utilization
attributes group |
A defined capacity is used as a basis for pricing
and the z/OS system is not running as a guest
on z/VM. |
Channel Path attributes |
The Resource Measurement Facility (RMF) has been
started. |
Common Storage attributes |
The Common Storage Area Analyzer (CSA Analyzer)
is started.
Note:
The CSA Analyzer is shipped and installed
with 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 and cross coupling facility (XCF)
data collected by the Resources Management Facility (RMF) Distributed
Data Server (DDS) |
- You are running z/OS V1.8 or higher 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 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

System hardware is z10 or above. |
Promoted Percent |
The z/OS V1.9 Workload Manager blocked workload
capability is enabled. |
Sysplex DASD attributes (Sysplex DASD Device, Sysplex
DASD Group, Sysplex DASD) |
A DASD filter situation is enabled. |
Suspend lock and spin lock data |
- You are running z/OS V1.10 or higher 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.
- Lock data collection is enabled on RMF.
|
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 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. |
zFS attributes |
zFS is specified as the file system on the monitored
system (that is, FILESYSTYPE TYPE(ZFS) is specified in SYS1.PARMLIB(BPXPRMxx).)
Note:
OMEGAMON XE on z/OS uses an address
space name of ZFS, unless the parameter KM3KZFSASNM=xxxxxxxx (where xxxxxxxx is the started task (STC) name of the
zFS address space) has been added to the &rhilev.&rte.RKANPARU(KDSENV). |
z/OS UNIX System Services attributes |
The address space where the 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 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 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 Situations.
