Express Setup

Express Setup defines a collection of resources, which is a static snapshot at the time of discovery. The collection is not updated dynamically even if a new resource appears a minute later. To capture new resources, update the collection. Add new resources to the collection (or system image) manually.

Review your monitoring environment over time. Add local knowledge to the monitoring setup. Modify the discovered resources so that you are not monitoring things that are not critical to your business. Modify the monitoring of a resource from the IP resource monitor (/IPMON) using the UM line command.

Aim to get your region to satisfy the following objectives:

• Everything that is monitored is useful so that each alert must be taken notice of and each status change is significant.
• Only the things you want are monitored, but in depth.
• Automated actions are targeted and valuable.

Business Value:

Monitoring everything wastes system resources and is distracting—inconsequential alerts can distract you while causing you to miss the important ones. Removing unnecessary monitoring also reduces the processing that the region has to do.

Additional Considerations:

Express Setup is a process that you run during your first logon to a new region. The process uses rules to discover the IP resources that are present at the time it runs. These resources include active address spaces, IP nodes within a certain number of hops, defined Open Systems Adapter (OSA), virtual IP address (VIPA), and Enterprise Extender (EE) devices, and more. If requested, Express Setup also defines simple business applications.

What Express Setup discovers can only be a starting point for your monitoring environment. Express Setup does not know your business or your wider network.

Everything Express Setup discovers is placed in a system image. You can have multiple system images, each containing a particular collection of resources. System images are given unique names—generally the system ID and a version number (for example, SYS1-0001). A region can have only one system image active at a time, which is usually loaded at region startup.

You can rerun Express Setup, but only advanced users should do this and only if a major reconfiguration has occurred since the last time it was run. Rerunning Express Setup creates another system image, which has to be reconfigured from scratch. The changes you made to the existing system image are not propagated to the new image.
