The monitoring subsystem reads hardware registers periodically (of order many seconds between updates) and makes data available to the MonLogger (for storage) and HyperMonVis (for real-time plots)
The frequency of reading the hardware is controlled by flashlists. See '''/home/daqowner/dist/share/hcalxt/flash'''.
The monlogger (saves data in files/db) controlled
by files in '''/home/daqowner/dist/etc/hcal/monvis'''.
This system is ''slow''! Don't expect anything to happen faster than once per minute or so (except the hardware reads, which can happen every 10 sec).
