The dSTATS daemon thread supports Replication Server’s counters feature by:
Managing the interface for flushing counters to the RSSD.
Calculating derived values when the daemon thread wakes up.
dSTATS manages the interface when Replication Server has been configured to flush statistics to the RSSD using the configure replication server command and the stats_flush_rssd parameter.
You can configure a sleep time for dSTATS using the configure replication server command and the stats_daemon_sleep_time parameter. When the daemon wakes up, it attempts to calculate derived statistics such as the number of DSI-thread transactions per second or the number of RepAgent bytes delivered per second.
