Management of Logs
When you start collecting the logs, information such as the operation dates and times, user names, operation details, and operation results are recorded.
In addition to being able to track the machine operations if any information leakage or trouble occurs, you can also quickly detect unauthorized use of the machine by reviewing and analyzing the collected logs.
For the log types, see the log specifications. Log Type

When the Log Collection Is Stopped
If the power of the machine is turned OFF due to power outage or other reason while collecting logs, log collection resumes from the last log before the power is turned OFF.
Exporting the Logs Automatically
You can configure the settings to export the logs as a CSV file automatically at a specified time every day and save them on a specified SMB server. Export is executed when the number of logs exceeds 95% of the limit (about 38,000) even before the specified time.
Configure this setting using Remote UI from a computer. You cannot use the control panel to configure the setting.
