System resources

The MainView for z/OS product keeps track of the performance of each system resource and reports how efficiently that resource is utilized by workloads.

By doing so, MainView for z/OS quickly detects problem situations where service objectives are not being met because of resource overutilization and contention. This information helps identify those resources that are underutilized, so that you can take action to optimize their performance.

MainView for z/OS gathers performance information about:

  • overall system performance
  • key processor aspects, including utilization (and users) of standard CP, zAAP, and zIIP processors, as well as utilization by PR/SM logical partitions (LPARs)
  • the entire I/O configuration, including channel paths, logical control units, and DASD and tape devices
  • SMS (system managed storage) groups
  • central, expanded virtual storage, and memory object
  • page data sets
  • data spaces and hiperspaces
  • System Resource Manager and its views of domains, MPL (multi-programming level) control, logical swaps, and expanded storage control
  • ENQUEUE and RESERVE
  • delays caused by contention for resources
  • Workload License Charges (WLC)
  • cache
  • data set usage
  • XCF
  • cryptographic coprocessor usage
  • JES2 and JES3 spool volumes
  • On/Off Capacity on Demand (OOCoD)
  • Spin and Suspend locks
  • the large frame area (LFAREA)
  • VSAM RLS
  • zFS activity

System-resource-utilization explains how to use MainView for z/OS to manage these system resources.
