upper - The upper limit of this statistic

lower - The lower limit of this statistic

name - The name of the statistic

unit - The unit of measurement for this statistic

desc - A brief description of the statistic

startTime - Time in milliseconds at which the measurement was started

sampleTime - Time at which the last measurement was done.

numberOfSamples - number of samples at present

runningTotal - running total of sampled data at present
