Using the Mainframe Short-term Capacity Overview view

The Mainframe Short-term Capacity Overview is a BMC Capacity Optimization view that enables you to manage the capacity of your mainframe environment. This view presents metrics for the most important objects in the mainframe environment:

• Central processor complexes (CPCs)
• Logical partitions (LPARs)
• z/OS images running on those LPARs
• Licensed software product groups such as CICS, DB2, IMS, and others
• Suites, which are user-defined groups of jobs and started tasks
• Applications, which are groups of subsystem transactions
• Business applications, which are business-related chains of subsystem transactions
• Storage Controllers and Storage Pools

The TrueSight console is the primary user interface for working with capacity views. You can access and work with all mainframe and infrastructure views and create custom views from this console. The TrueSight console is hosted on the TrueSight Presentation Server and can be accessed from a web browser or a mobile device.  Access to this component is enabled through integrated system authentication with Atrium Single Sign-On.

You can access the TrueSight console by clicking the following link on the home page of the TrueSight Capacity Optimization console:

Once you are logged into the TrueSight console, you can access the mainframe views by navigating to Capacity > Views > Mainframe > Mainframe Short-term Capacity Overview.

You can use the Mainframe Short-term Capacity Overview to display summarized and detailed metrics for mainframe objects, identify metrics that need attention, and begin the analysis of potential problems. This view can help you answer critical questions related to your mainframe environment, such as:

• How much of your central processor (CP) resources did your data center use over the last week?
• Is yesterday's usage pattern significantly different from the previous seven days?
• How close is your machine to its physical capacity?
• How close is your machine to defined capacity limits that determine your software license charges?
• How close is your machine to its central storage capacity?
• How much use are you making of specialized processors such as:
  • IBM System z® Application Assist Processors (zAAPs)
  • System z Integrated Information Processors (zIIPs)
  • Integrated Facilities for Linux® (IFLs)
