The
Buttons
If the
Enable logging checkbox and/or the
Capture each page of graph images automatically
checkbox is selected, you need to keep a check on the size of their folders.
Pressing any of the Maintenance buttons will display the Maintenance window:

This should be reasonably self-explanatory. Pressing the Trim Now and Delete Now buttons will
perform the specified actions immediately.
The deleted images are, in fact, sent to the Recycle Bin so they can be retrieved if
necessary but lines deleted from the Log file are lost.
RouterStatsHub creates a Capture folder when it first runs and it's highly recommended that
you use this folder exclusively for RouterStatsHub captured images.

If a maintenance schedule has been set for the Log or the Captured images,
the appropriate
Maintenance button will have a tick icon alongside it.

Obviously RouterStatsHub has to be Open for this maintenance to occur but it does not need to be actually
running.
