Track changes in audited entities
After you make changes to your system, if you want to monitor and see the logs, you can follow these steps:
1.) Go to Settings > System > Auditing > Audit Summary View.
Usually, if there are any changes made, you can see them recorded here.
View and manage audit log files
If you would like to see or manage the audit log files, you can follow these steps:
1.) Go to Settings > System > Auditing > Audit Log Management.
You will see the logs your system has created.
These log files can grow pretty big over time, so it’s a good idea to delete them when they are no longer needed. You can delete the oldest logs, but you cant actually delete the current log, because it’s in use.
