Hello Jeremy, As it is right now the monitoring app is useless. It will take OK data for about 30 seconds. I think until it encounters an ECAL config event. From that moment on, the event rate in the app drops to less than 1 Hz, it seems it is only picking up the ECAL config events. Seems the ET thread is continually crashing.
