Stop atStop at: Stops the measurement at the time specified in the Stop atStop at field on the
right.
DurationDuration: Performs the measurement for the duration of time specified on the
right.
Memory allocationMemory allocation
Allows you to specify how the measurement will be stored in the Network
Master's memory.
Use all storageUse all storage: When Network Master's memory became full of measured
data, the whole measurement is stopped.
ContinuousContinuous: When Network Master's memory became full of measured data,
the oldest records in that memory will be overwritten.
When the memory became full, it is recorded in Event log.
The Network Master's memory size (the file size of measurement results) is 64
Mbytes per one port. The result file size is less than 64 Mbytes because it is
compressed when saving to the file.
Estimate of test durationEstimate of test duration
Contains an estimation of the time (in days, hours, minutes and seconds)
before the whole memory will be filled out by the test. During an ongoing
measurement, the estimate will be recalculated periodically.
