I found the following in Summariser by decompiling the class:
sb.append("/s Avg: ");
sb.append(longToSb(tmp, s.getAverage(), 5));
sb.append(" SD: ");
sb.append(doubleToSb(tmp, s.getStandardDeviation(), 5, 2));
sb.append(" 2xSD(~95%): ");
sb.append(doubleToSb(tmp, s.getDoubleStandardDeviation(), 5, 2));
sb.append(" 3xSD(~99%): ");
sb.append(doubleToSb(tmp, s.getTripleStandardDeviation(), 5, 2));
sb.append(" Min: ");
sb.append(longToSb(tmp, s.getMin(), 5));
sb.append(" Max: ");
sb.append(longToSb(tmp, s.getMax(), 5));
sb.append(" Err: ");
sb.append(longToSb(tmp, s.getErrorCount(), 5));
sb.append(" (");
sb.append(s.getErrorPercentageString());
sb.append(")");
And RunningSample:
public double getStandardDeviation()
{
return Math.sqrt(Math.abs(this.sumOfSquares / this.counter -
getAverage() * getAverage()));
}
public double getDoubleStandardDeviation()
{
return Math.sqrt(Math.abs(2L * (this.sumOfSquares / this.counter) -
getAverage() * getAverage()));
}
public double getTripleStandardDeviation()
{
return Math.sqrt(Math.abs(3L * (this.sumOfSquares / this.counter) -
getAverage() * getAverage()));
}
Unless someone has seen this before it looks like someone customized JMeter
years ago.
Thanks for the responses.
