Criteria for Sending Alert Emails Regarding Audit Log Storage Usage

Event information that can affect the system disk usage continues to accumulate. To manage this, three threshold values are set based on storage capacity, and whenever the stored event volume exceeds each threshold, a notification event is triggered to the administrator. The current storage volume of the audit log can be checked in the graph at the top-right corner of the ‘Audit Log’ page.

‘Audit Log Space Usage’ Graph Screen

If the amount of stored events exceeds the set threshold for the '3rd Warning', the system will automatically delete the oldest events in order from the time the event occurred, up to the amount set for the '1st Warning' threshold to protect the system.
The threshold is set as a percentage based on the total disk capacity. To configure this, click the ‘Update’ button below.

• Input rules: A number between 1 and 99
• Input value length: 1 ~ 2 characters
• Default input value: The previously set value

If the above rules are violated, the following error message will appear.

Error message screen

Please enter a number between 1 and 99 for the 1st warning.

Please enter a number between 1 and 99 for the 2nd warning.

Please enter a number between 1 and 99 for the 3rd warning.
