Dear QC experts,
for the MCH monitoring we would like to plot and check the channel-by-channel occupancy of our readout electronics. In continuous readout mode, the occupancy would be defined as the number of digits in a given time interval, for example one orbit.
The idea would be to gather the digits from the O2 decoding via DPL, using this kind of workflow:
TimeFrameSender -> o2-mch-raw-to-digits-workflow -> o2-qc
At the level of the
raw-to-digits workflow it is possible to “count” the number of orbits using the information provided by the RDHs, however the RDHs are not available anymore once the digits are created and sent.
Is there a standard way to retrieve the number of orbits spanned by a given DPL message in QC? Or are we forced to assume that each DPL message corresponds to a full TF, and in this case how do we get number of orbits in the TF?
Thanks a lot!
