clear
public void clear()

addValue
@Deprecated public void addValue(long newValue)
Deprecated.UseaddSample(SampleResult)
insteadAdd the value for a single sample.- Parameters:
newValue
- the value for the new sample
-
addBytes
public void addBytes(long newValue)
-
addSample
public void addSample(SampleResult res)
Add details for a sample result, which may consist of multiple samples. Updates the number of bytes read, error count, startTime and elapsedTime- Parameters:
res
- the sample result; might represent multiple values
-
getTotalBytes
public long getTotalBytes()
-
getMean
public double getMean()
-
getMeanAsNumber
public Number getMeanAsNumber()
-
getStandardDeviation
public double getStandardDeviation()
-
getMin
public long getMin()
-
getMax
public long getMax()
-
getCount
public int getCount()
-
getLabel
public String getLabel()
-
getErrorPercentage
public double getErrorPercentage()
Returns the raw double value of the percentage of samples with errors that were recorded. (Between 0.0 and 1.0)- Returns:
- the raw double value of the percentage of samples with errors that were recorded.
-
getRate
public double getRate()
Returns the throughput associated to this sampler in requests per second. May be slightly skewed because it takes the timestamps of the first and last samples as the total time passed, and the test may actually have started before that start time and ended after that end time.- Returns:
- throughput associated to this sampler in requests per second
-
getAvgPageBytes
public double getAvgPageBytes()
calculates the average page size, which means divide the bytes by number of samples.- Returns:
- average page size in bytes
-
getBytesPerSecond
public double getBytesPerSecond()
Throughput in bytes / second- Returns:
- throughput in bytes/second
-
getKBPerSecond
public double getKBPerSecond()
Throughput in kilobytes / second- Returns:
- Throughput in kilobytes / second
