An easy to use benchmarking statistics class. This isn't yet very sophisticated, but quite capable of producing a nice benchmark statistics for (multithreaded) services with very little code.
Usually, you just need to create a benchmark object
moost::utils::benchmark bm("harold", num_threads);
and then pass a reference to this object to each thread running requests against a service. Within each thread, you can then create a timer object for each request:
If the timer object goes out of scope, it will automatically stop the timer and add the elapsed time to the set of times for the default result specified in the constructor (unless explicitly provided, this will be "error"). You can explicity stop the timer with a different result by calling the stop() method on the timer object. The default result when calling stop() explicitly is "success". You're free to use more results that those two.
After all threads have been joined, simply call the output() method of the benchmark object:
bm.output(std::cout);
This will provide you with histograms for each result type as well as a combined histogram and statistical analysis of the distribution of request times.
