Reports in the Application Builder administration tool
enable you to see how users interact with the end-user application.
Reports can be found on the
Reports tab in the
Application Builder administration tool settings page (the cog icon on the
navigation bar). After reporting is enabled, reporting data is collected and stored.
Note: Reports
work by logging application usage data as fields into a Watson Explorer Engine search collection that populates the log
entity in Application Builder. Search is disabled by default in the
log entity configuration because the reports are viewed in the administration
tool.
Purging the logs collection
Because data for reports is stored in a collection data store that populates the
log entity, periodically create a new collection and delete the old one as it
becomes full. The time interval you choose to delete the
logs collection will
depend on the number of users and their activity in the application. To delete old report data:
- In the Watson Explorer Engine administration tool, find the
logs search collection and duplicate the XML to another collection.
- Click the xml link, which is located on the right side of the collection
heading.
- Click the duplicate button.
- In the collection Overview tab, click start.
- In the Application Builder administration tool, on the
log entity configuration page, change the data store to
logs-copynumber collection, and then click
Save.
- Delete the old search collection from Watson Explorer Engine.
Memory consideration
Fields that populate each report are fast-indexed. If you're concerned about the amount of memory
that is used to store these fast-indexed fields in RAM, for reports that you do not use, you can
remove the fast-indexed fields. Fast-indexed fields are listed in the search collection tab in the Fast Index field in the logs
collection.
The system reports use the following fast-indexed fields:
- Most-viewed entities
- entity_title
- params_controller
- params_action
- Top clicked results
- params_entity_title
- params_controller
- Top expanded queries
-
- Top IP addresses
-
- Top modified queries
-
- Top queries
-
- Top spelling corrections
-
- Top zero-document queries
