Logging

Current

the logging is done within the Event Handler. Every event triggers an entry in the log file. There are 37 columns but not all of them are relevant for each event. Only relevant data is logged as a number and other entries are saved as ‘nan’ to simplify reading of the log file.

0. time

1. global_pointer

2. period_idx

3. event_code

4. pPre_0

5. pDepre_0

6. pPre_after_0

7. pDiff_0

8. tSwitchDepressure_0

9. tSwitchDepressureEst_0

10. tSwitchPressure_0

11. tSwitchPressureEst_0

12. gradientPressure_0

13. gradientDepressure_0

14. gradientPressureEst_0

15. gradientDepressureEst_0

16. riseTime_0

17. fallTime_0

18. pPre_1

19. pDepre_1

20. pPre_after_1

21. pDiff_1

22. tSwitchDepressure_1

23. tSwitchPressure_1

24. gradientPressure_1

25. gradientDepressure_1

26. fallTime_1

27. riseTime_1

28. period

29. delay

30. pressure_pulse_width

31. depressure_pulse_width

32. pump_stroke

33. depressure_valve_counter

In future

The logging module is a separate Python process that uses Channel Access to subscribe to “logging” PVs hosted by other serves.
