Hi Pete,

my suggestion for an online monitor would be:

Similar to onlineGUI, it is meaningful to have a panel with buttons to
switch between detector groups.
On pushing that button, a "detector window" (e.g. TOF) is showing
TOF-related information. This could (should) be a plot of quantity versus
runnumber, e.g. T0, MeanADC, Pedestal, ..., i.e. those which were
determined once per run, showing the evolution, for let's say the latest
500 runs. All of these quantities could be plotted with different colors
or symbols in the same detector canvas. Since we are only interested in
changes, the abolute number which is plotted is arbitrary. Thus we could
either subtract the value of the leftmost datapoint of the plot, or the
avrage value of the quantity within the 500 runs. We could also think of
normalizing the deviation from the averag to the average and display the
percentage. (However I have some objection with this, since "relative"
changes of calibration constants are less important that rather absolute
changes.
All quantities shown should only be read from the database.
I think most ingredients are already there, just need to be put together.

What do you think?
