The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

(DeltaNetMsgToClientTime/DeltaServiceTime)*100 where:
DeltaNetMsgToClientTime: difference of 'sum of time waited for sessions of foreground processes on the 'SQL*Net message to client' event' between sample end and start
DeltaServiceTime: difference of 'sum of time waited for sessions of foreground processes on events not in IdleEvents + sum of 'CPU used when call started' for sessions of foreground processes' between sample end and start
