Length of window over which threshold counts are summed, specified in intervals of 500 TimeTicks (i.e., 5 seconds). This window is broken down into 5 second sampling periods for purposes of checking the threshold conditions, and determining when the actions specified need to take place when the condition occurs. If this object is written with a value that is not evenly divisible by 500, the agent will internally round the value up to the closest integral of 500 before it is used in threshold calculations (i.e., a value of 12 can be written, but will be interpreted as 15). Notes: 1.) A value of zero indicates an infinite duration window if the value of s3EnetThreshCondition is crossValue(2) or overValue(3). 2.) If the value of s3EnetThreshCondition is overRate(4) or overRatio(5), a value of zero is equivalent to a duration window of 5 seconds. 3.) If the value of s3EnetThreshType is linkStatus(12), this value of this object is ignore and assumed to be infinite.
