Find the Performance task by the circular chart icon on the left navigation:
Investigate Data
The Investigate Data action brings you to the Perspectives List for all packages loaded on this GUI node.
Instead of the tree view, you are presented a sorted list, which can be customized according to your preferences. The default first view is to show only the Collection Services package.
The Context section at the top can be modified to quickly change the Collection library, graph interval, and collection name before selecting to view a perspective. Select your collection first. When you click the perspective name, it launches to those views for the selected collection and uses the selected graph interval for display.
Features to notice on this Perspectives List page:
- Select and deselect packages to change the list of the perspectives shown
- Hover over a perspective to view the location hierarchy information
- The columns can be customized by the triple-dot icon on the right of the column headers
- The Full SQL can be displayed and copied. The alias information is provided in comments within the SQL to help you create the correct aliases to run the query successfully.
- This page functions as the full search feature by providing every field to search (SQL, metrics & views list, titles)
- The selected fields of the table are saved in your preferences. So when you return to Investigate Data after launching to a chart, they are restored.
Notes on PML package location: PDI now loads the PML packages from the managing node. Previously, original Navigator loaded the PML from the target system. Any custom charts you want to use need to be in the IFS directory where created on that managing node. Custom perspective functionality is not available on this version of Navigator for i.
Charts
The charts look and function similar to the Dojo charts provided with the updates from 2020.
Reference the Packages & Perspectives page for information on drilldown handling for required selection.
The General Health Indicators warning and action thresholds are displayed with the tooltips:
Graph History - Summary & Details
