Monitor the VFAT S-bit rate
Description
Request received from the (ME0 stack) ops team: monitor the VFAT S-bit/trigger rate and expose it in the monitoring suite Web UI. The metric(s) could be the sum of the VFAT S-bit rates or the per-VFAT S-bit rates. I'm leaning towards the second option since it provides more information (and since we are already monitoring a few per-VFAT parameters).
