                                 throws InterruptedException

If there is a value indicating the accumulated amount of time spent on something it is possible to build a series of values representing the percentage of time spent on doing something. For example:

at point T1 the system has spent A milliseconds performing tasks at point T2 the system has spent B milliseconds performing tasks

so between in a timeframe T2-T1 the system spent B-A milliseconds being busy. Thus (B - A)/(T2 - T1) * 100 is the percentage of all time the system spent being busy.

Parameters:

name - the name of the value, which allows the collector to be used for multiple values

value - time spent on the task in milliseconds (A or B in the example above)

time - system time in milliseconds (T1 or T2 in the example above)

Throws:

InterruptedException - if a lock could not be obtained

resetStats

protected void resetStats(String name)

Reset stats.

Parameters:

name - the name
