Audit log is a collection of events in a chronological order, which is written to a file within the appliance. The audit log files are generated at /var/log/netapp/audit location and the file names follow one of the below naming conventions:

  • audit.log: Active audit log file that is in use.

  • audit-%d{yyyy-MM-dd-HH-mm-ss}.log.gz: Rolled over audit log file. The date and time in the file name indicates when the file was created, for example: audit-2022-12-15-16-28-01.log.gz.

In the SCV plug-in user interface, you can view and export the audit log details from
Dashboard > Settings > Audit Logs Tab
You can view operation audit in the audit logs. The audit logs are downloaded with the Support bundle.

If Email settings are configured, SCV sends an Email notification in the event of an Audit Log Integrity Verification failure. An Audit Log Integrity Verification failure can happen when one of the files is tampered or deleted.

The default configurations of the audit files are:

  • Audit log file in use can grow to a maximum of 10 MB

  • A maximum of 10 audit log files are retained

Rolled over audit logs are periodically verified for integrity. SCV provides REST APIs to view logs and verify their integrity. A built-in schedule triggers and assigns one of the following integrity statuses.

Status

Audit log file content is modified

NORMAL

ROLLOVER DELETE

- By default, only 10 files are retained

Configure syslog servers

Audit logs are stored within the appliance and are periodically verified for integrity. Event forwarding allows the you to obtain events from the source or forwarding computer and store it in a centralized computer, which is the Syslog Server. Data is encrypted in transit between the source and the destination.
