conlog reporting of frequently changing EPICS channels, daily report

Patrick, Dave

The conlog reporting of frequently changing EPICS channels has discovered several code issues in the past week. Conlog reports hourly those channels which have logged 500 or more changes in the previous hour. I have written a python script to concatinate 24 hourly reports into a daily report, which I'll post in the alog. 

Below is the log from yesterday (Monday 11/17). We discovered a guardian node which was setting the end station SUS L1_LOCK_L filters RSET (clearing history) at 16Hz. This was fixed between 1pm and 2pm.

The per-second number is calculated as total/(hours-active * 3600). Numbers in the 16 range are most probably front end or guardian related, higher than 16 most probably Beckhoff or scripts.

Some of the GRD channel changes are likely reflective of actual changes in the system.  It's not clear to me that conlog should be monitoring the following guardian channels:

_STATUS
_GRDMSG
_USERMSG
_NOTIFICATION
_STATE_S
_STATE_N
_TARGET_S
_TARGET_N
_OK

None of those channels are set by users, so they may change as fast as the system changes.
