Most counters sample data with minimal effect on Replication Server performance. Counters that may affect performance—intrusive counters—are enabled separately so that you can enable or disable them without affecting the settings for non-intrusive counters.
Three counters may affect performance:
TranTimeLast – records the time, in one-hundredths of a second, for the DSI thread to process the last transaction in a run.
TranTimeMax – records the maximum time, in one-hundredths of a second, for the DSI thread to process a transaction in a run.
TranTimeAve – records the average time, in one-hundredths of a second, for the DSI thread to process a transaction in a run.
You can enable or disable intrusive counters using the admin stats_intrusive_counters command. The default is “off.” The syntax is.
admin stats_intrusive_counters, { 'on' | 'off' }
