How to delete/reduce the data from the JBoss ON database

Issue

• Our DBA requested deleting some data from the JON schema. Requesting information on what can be safely deleted without affecting the setup or configuration of JON.
• I have some confusion about the setting properties.
  • Delete Availability Data --31 == will delete only availability information after 31 days. So no availability information after 31 days.
  • Delete Events --14 == will delete Events(log related) after 14 days. So no events related information after 14 days
  • Delete Measure Trait : 356 === keep trait values for 365 days
  • Delete Response Time Data: 31 === Not sure what does it mean by Response time data. Is it collected metrics?
    So to keep data for One year, do I need to make "Delete Response Time Data" --365?
• If you have some DB space issue, can we change some setting which will remove older information (only keep 3 months instead of 6 months).
