中级别 1自动化macos

说明

Retention can be set to respect both size and longevity.

When a third party tool is in use to allow remote logging or the store and forwarding of logs, this is a supplemental source of data. Note: If you organization has storage constraint issues, you can add a storage value limit to expire-after: in addition to days retained. For example: expire-after:30d OR 5G or expire-after:30d OR 10000M. In addition, your organization may also look at the what audit flags are...
