MIDAS interface for WAGASCI online monitor |
|
|
Hello!
This question is rather complex so please forgive me if I leave out some
details.
I am currently developing an online monitor to check the data quality for the
WAGASCI experiment. The online monitor would show (almost in real-time) the
gain, the dark noise, and the pedestal for all the channels, the 2D tracks
inside the detectors for each spill and so on. This is possible because we can
continuously calibrate the WAGASCI electronics even during a Physics run.
Anyway, as I said during the MIDAS workshop, right now, we do not use MIDAS as a
frontend DAQ to readout the Physics data from the electronics (we use Pyrame and
the BabyMIND DAQ for that). One day, we might have Pyrame and the BabyMIND DAQ
send the Physics data to MIDAS in the form of MIDAS events ... but we are still
far from it (mainly because of lack of man-power on the BabyMIND side). I do not
think we will ever achieve this goal in the lifetime of the experiment because
the BabyMIND people do not see any added value in using MIDAS as a DAQ. But this
is another issue so I am going to drop this argument for now.
The fact is that I have written and tested all the code to continuously read the
WAGASCI electronics in real-time. I now would like to display some histograms and
figures in a MIDAS custom page that would automatically refresh/update. I have
not written the visualization part yet, because I would like to hear your
feedback first.
So my questions are. Suppose you have some ROOT histograms updating in real
time, what is the best way to show them in a MIDAS custom page? Is the ROOT
HttpServer an option here? If not ROOT, is there a better way to display
histograms in a web page?
I could have avoided the long introduction and just asked the questions but I
wanted to give you a little background.
This is a cartoonist impression of what I would like to achieve.
Thank you
