Analysis controls

This reference lists analysis controls that you can set up.

Keyboard navigation
You can use keyboard to navigate through the identified anomalous activities. When the interval data is loaded in z/OS® Workload Interaction Navigator, the focus is on the Analyze button by default. Press the Enter key to start automated analysis. You can keep pressing Enter key to review the next activity, or move the focus to other buttons like the Autoplay button by pressing Tab key or Shift+Tab keys, and press the Enter key to take the focused action. When the focus is on the Analyze button, you can press ↓ key to jump into the summary table. The first time you press ↓ key, the focus is on the See More button of the first activity. You can press:
  • Enter key to expand and contract the See More section
  • ↓ key to review the next activity
  • ↑ key to review the previous activity
  • → key to review the next key activity with K under the Global/Key column if there is any key activity. Otherwise, use the key to review the first activity of the next activity group.
  • ← key to review the previous key activity with K under the Global/Key column if there is any key activity. Otherwise, use the key to review the first activity of the previous activity group.
Analysis System
To do analysis with activities from one specific system, select the Home tab on the right, and set Analysis System appropriately. Then z/OS Workload Interaction Navigator analyzes data within the system you specify only. This applies to sysplex analysis only.
Home tab
Analysis Scope
To do analysis with activities from one specific z/OS component or middleware product, select the Home tab on the right, and set Analysis Scope appropriately. Then z/OS Workload Interaction Navigator analyzes data within the scope you specify only.
Focus Area
For an Analysis Type that produces correlated activity groups, z/OS Workload Interaction Navigator only presents groups with at least one activity from an Analysis Scope, or with a specific (partial) jobname or lock ID. This is useful to further reduce the correlated activity groups to only those that meet a predefined problem criteria if there is any. For example, If you specify a lock ID, the activity groups that do not contain the specified lock ID are not displayed. You can focus on the activities with the significant impact from this lock. To use this analysis capability, select the Home tab, set Focus Area, activate focus area, click the checkbox icon icon to add a check mark, and click the Analyze button.
Correlation Technique
Defines the types of correlation that are used to establish Correlated Activity groups:
CPU utilization
The activities are limited to those that match key CPU utilization points.
Highest Peak
All activities are grouped by the highest peak points.

Bookmark
To save an Activity for review later, select the Advanced tab, click the Bookmark icon icon, and add a description. Bookmarks are most useful when not using Automated Analysis. Bookmarks remain until the analysis session for the input IBM® z/OS Workload Interaction Correlator interval(s) end(s).

Session settings
The Session Settings icon icon controls IBM z/OS Workload Interaction Correlator Automated Analysis data and anomaly thresholds for the current analysis session. When this icon is white, the defaults are in effect. When this icon is orange, one or more default settings have been changed. For more information, see Session settings.
