Use this window to review statistics collected over a series of time intervals which monitor SRTP packets that failed authentication or were flagged as replay packets. This information could help identify malicious media packet attacks or might be used to troubleshoot "no audio" calls using SRTP. 

To set the time interval and the number of statistic sets that are stored, refer to System - Interval Statistics.
