16.1. Deleting Audit Records

Audit records are created automatically in Satellite. You can use the foreman-rake audits:expire command to remove audits at any time. You can also use a cron job to schedule audit record deletions at the set interval that you want.

By default, using the foreman-rake audits:expire command removes audit records that are older than 90 days. You can specify the number of days to keep the audit records by adding the days option and add the number of days.
