Configure Data Expiration Settings in Vision

Use Data Expiration Configuration to define the amount of time that Vision retains data collected from monitored devices. Any data that is older than a specified age is expired and removed from the Vision database, and this information is no longer available for reporting.

When configuring data-retention time periods, keep in mind that aggregated values are retained in the Vision database for a predefined time:

  • 15 minute values are retained for 6 months
  • 1 hour values are retained for 12 months
  • 1 day values are retained for 18 months

Note: You must be an administrator to configure data expiration settings.

  1. On the Vision Configuration menu, click Data Expiration to display the Vision Data Expiration Configuration dialog box.

    • In the Replication Summary Lifetime field, enter the number of days to retain replication summary values.
    • In the Scalar Data Lifetime field, enter the number of days to retain Scalar library data.
    • In the vmPRO Value Lifetime field, enter the number of days to retain vmPRO values.
  3. Click Save to save the settings.
