This screen allows you to perform a number of administrative actions.
The status section at the top of the screen is refreshed every 5 seconds. You can disable the refreshing by clicking on the autorefresh icon.
Tasks launched in this screen are all executed asynchronously: when you hit the launch button the task is added to a job queue. A separate worker process will execute the tasks from the queue.
All the actions (and more) can also be performed synchronously from the command line with the frepplectl script: see Command line
It is also possible to launch tasks through a web interface: see Remote commands
