IBM Tivoli OMEGAMON XE V3.1 Deep Dive on z/OS

192 IBM Tivoli OMEGAMON XE V3.1 – Deep Dive on z/OS

6.1 Monitoring your z/OS environment

As was discussed in Chapter 2, “IBM Tivoli OMEGAMON XE components and

architecture” on page 19, the primary interface for IBM Tivoli OMEGAMON XE

and OMEGAMON DE is the Tivoli Enterprise Portal. IBM Tivoli OMEGAMON XE

products running on z/OS maintain the 3270-based interface for various

OMEGAMON classic and OMEGAMON II CUA products. These interfaces can

be accessed directly using the 3270 terminal or emulation or through the portal

Host on demand interface.

The discussion starts with a general walkthrough the Tivoli Enterprise Portal

interface including out-of-the box navigation and other facilities that are available

in Tivoli Enterprise Portal in 6.2, “Working with IBM Tivoli OMEGAMON XE” on

page 193.

Tivoli Enterprise Portal provides a great deal of flexibility for operators to define

new workspaces and customize existing ones. You can perform advanced

functions for customizing the workspace, including working with background

images and linking workspaces. This discussion is presented in 6.3,

“Workspaces and links” on page 196.

Situations provide a mechanism for operators to get automatic notification of

potential system problems. When a situation fires, the alert icon is shown in the

resources tree and alert operators, providing an excellent early warning system.

We discuss situation manipulation in 6.4, “Working with situations for z/OS” on

page 211.

Historical data collection into Tivoli Data Warehouse can provide insight into how

the system performs and can be used as an information source for forecasting

future system performance. Although IBM Tivoli OMEGAMON XE V3.1.0 has not

fully exploited the facilities provided by Tivoli Data Warehouse, such as

summarization and pruning, the data collection facility is still readily available. We

discuss this in 6.5, “Historical data collection” on page 221.

IBM Tivoli OMEGAMON XE on z/OS provides the basic monitoring for your z/OS

system. We discuss some scenarios for z/OS-based monitoring, especially the

new features that are available with IBM Tivoli OMEGAMON XE on z/OS V3.1.0,

in 6.6, “IBM Tivoli OMEGAMON XE on z/OS new features” on page 226. Other

z/OS-related scenarios with sysplex are discussed in 6.7, “Sysplex-related

monitoring” on page 230.

We also provide some CICS-based scenarios for IBM Tivoli OMEGAMON XE for

CICS on z/OS in 6.8, “CICS Short on Storage (SOS)” on page 240.
