Tivoli OMEGAMON XE on z/OS Workspaces

Overview

Tivoli OMEGAMON XE on z/OS provides two sets of predefined workspaces: sysplex-level and system-level. These workspaces provide data in tabular and graphic form and enable you to effectively monitor the availability, resource consumption, and performance of your sysplexes and their component z/OS systems.

The sysplex-level workspaces provide data on coupling facilities, global enqueue, GRS ring systems, report classes, service classes, resource groups, shared DASD groups, and cross-system coupling facilities (XCFs) used by each sysplex. The system-level workspaces report data on address space CPU utilization, storage usage and bottlenecks, channel activity, common storage usage, single image DASD device usage, Workload Manager service class resource usage, and LPAR cluster activity for the z/OS images that participate in the sysplex, as well as the status and configuration of any installed IBM cryptographic coprocessors.

Tivoli OMEGAMON XE on z/OS provides a Sysplex Enterprise Overview workspace, which allows you to monitor the status and performance of your sysplexes and shared resources at a glance.

The physical view of the CandleNet Portal Navigator shows an enterprise as a mapping of platforms, systems, agents, and monitored resources. In a sysplex environment, monitored sysplexes appear between the platform and system levels of the Navigator tree, listed by their managed system names.

z/OS Systems

SYSPLEX1:MVS:SYSPLEX sysplex

SYSPLEX2:MVS:SYSPLEX sysplex

Below each sysplex name are entries that represent a set of common objects shared by the sysplex that are monitored by Tivoli OMEGAMON XE on z/OS, and entries that represent z/OS systems or LPARs being monitoring by Tivoli OMEGAMON XE on z/OS.

System2

Each entry is associated with one or more workspaces which provide information on those monitored objects. For example, the Shared DASD Groups Data for Sysplex entry is associated with the Shared DASD for Groups workspace, which provides information about sysplex-wide activity of shared DASD devices. From the Shared DASD for Groups workspace you can link to the Shared DASD Devices workspace, which displays information about the activity of the shared devices for a selected group, averaged over all systems in the sysplex.

Under each system name is an entry for each type of resource monitored by a Tivoli OMEGAMON XE monitoring agent on that LPAR. For example, if you have installed both Tivoli OMEGAMON XE on z/OS and Tivoli OMEGAMON XE for IMS, you will see two entries at this level:

System1

MVS Operating System

SYSPLEX:SYSTEM1:MVSSYS

   IMS

Under each agent entry is an entry for the managed system.

plexname:MVS:SYSPLEX

where plexname is normally the true name of the sysplex but could be configured to be an alias name for the sysplex.

plexname:smfid:MVSSYS

where plexname is normally the true name of the sysplex but could be configured to be an alias name for the sysplex. (This part of the LPAR managed system name typically matches the plexname component of its parent sysplex in the navigation tree.) The smfid component is the true SMF ID for the LPAR being monitored.

To see a description of a particular workspace, or to find instructions for accessing it, select its name in the Contents tab. Workspaces are listed alphabetically by type (sysplex-level or system-level).

Reporting historical data

All of the system-level workspaces except the Enqueue and Reserve Summary and Address Space Bottlenecks workspaces can record and report historical data. All of the sysplex-level workspaces, with the exception of the Users Data for CF Structure, GRS Ring Systems Data for Sysplex, and the Members Data for XCF Group workspaces can record and report historical data.

Workspace views that have history recording enabled have the history icon in the upper left corner.

In order for historical data to be reported, historical data collection must be configured and enabled on all Candle Management Servers in a sysplex. (Since the identity of sysplex proxy Candle Management Server can vary, the CandleNet Portal cannot know which address space is currently serving as the proxy.)

For information on configuring Tivoli OMEGAMON XE on z/OS data storage, see Configuring OMEGAMON XE on z/OS.

For information on configuring and reporting of historical data collection with the CandleNet Portal, see Historical Reporting Overview, Historical Reporting, Configure History Data Collection, and Using OMEGAMON XE on z/OS.

Custom workspaces

You can modify the predefined workspaces to better meet site-specific monitoring requirements, or create your own workspaces for specific monitoring purposes. (If you modify the predefined workspaces, you must save them with a new name.)

For help creating custom workspaces, see Edit a Workspace, Create a Workspace, Workspace Customization Options.

Accessing Tivoli OMEGAMON XE on z/OS workspaces

To access Tivoli OMEGAMON XE on z/OS workspaces from the Navigator:

  1. Expand the Navigator tree by double-clicking the Enterprise item, if necessary.

  2. Select (click) z/OS Systems.

Under OS/390 you will see entries for all the sysplexes you are monitoring with IBM Tivoli OMEGAMON XE on z/OS. When you expand the beside the sysplex managed system name, you will see the Navigator items associated with the sysplex-level workspaces. You will also see entries for every system (LPAR) in the sysplex.

When you expand a system entry, you see a Navigator item for the Tivoli OMEGAMON XE on z/OS  agent (MVS Operating System), as well as an item for every Tivoli OMEGAMON XE agent that you have installed on that system (for example, Storage Subsystem for Tivoli OMEGAMON XE for Storage).

When you select the managed system name of a sysplex or an LPAR ( for example, LPAR320M:SYSG:MVSSYS), a list of available workspaces for the sysplex or LPAR is displayed below the name.
