Description |
|---|---|
| Type | Int |
| Default value | 0, which indicates that audit logs are not retained. The unit is seconds, and the unit does not need to be specified when the parameter is configured. |
| Value range | [0, +∞) |
| Modifiable | Yes. You can use the ALTER SYSTEM SET statement to modify the parameter. |
| Effective upon OBServer node restart | No. The setting takes effect immediately. |
Considerations
When a new log file is generated during log archiving, the system checks whether to prune logs. This parameter and audit_log_max_size can take effect at the same time.
Examples
Set the maximum retention period of audit logs to 2 hours.
