We have a special record to deal with digitizers, where the waveforms associated with each channel have fields with imaginative names like .ARY1, .ARY2 etc. These waveforms hold the past few pulses of Low-level RF data, and are meant to be picked up by the archiver when a trip occurs and new data are available. These internal arrays (ARY1, ARY2, etc.) are only read from the hardware (SIS or Joerger digitizers) upon a trip.
It seems that these fields are not being successfully monitored. Two stray waveforms have appeared in the archiver, but hundreds of others have not.
We could strobe these data out to traditional waveform records (and have in some cases). Data handled in this way do appear in the archiver, indicating that the monitoring worked.
Is there a way to have our cake and eat it too? Can we monitor these separate fields in the channel archiver or do we have to copy the data one more time to trigger a monitor?

Is your special record type calling db_post_events for EACH ARYx field when it
is updated?
Is your special record type following all the rules about how to process a record?
Please review the chapter "Record Suppport" in the Application Developer's Guide.
