This is a running count of individual log records this Correlation Unit has processed. An admin watches this counter's rate as the basic throughput indicator for the log-ingestion pipeline, and a rate that drops to near zero while cpseadProcAlive still shows running would point to a specific stalled job rather than the daemon itself being down. For example, this counter's growth rate slowing from thousands per minute to single digits would prompt checking the individual job states rather than assuming the whole Correlation Unit crashed.
