OTOBO / Znuny – Plan and Manage System Maintenance

System maintenance is a central part of any IT administration. Some maintenance tasks require a temporary shutdown of live operations. In these cases, it is particularly important to inform users in a timely manner and keep the system accessible only to administrators.

OTOBO offers a clear interface in the Admin Interface with the System Maintenance module to create and adjust maintenance windows and to warn users via login notice or in-app notification.

TIP

You can set the default texts for login and in-app messages in the System Configuration:

You control the timing of the in-app warning before maintenance begins using SystemMaintenance::TimeNotifyUpcomingMaintenance (minutes before start).

Session Management

In addition to planned maintenance, it is often necessary to monitor active user sessions and terminate them if necessary.

In the Session Management module, you can see all currently logged-in users:

• Terminate Single Session: Click Terminate This Session
• Terminate All Sessions Except Your Own: Click Terminate All Sessions Except Your Own

These functions help to quickly clean up the system after maintenance or in case of security incidents.
