Usage

// Counter
var counter = new bench.Counter('forLoopCounter');
counter.start();
for (var i = 0; i < 100; ++i) {
  counter.incr();
}
counter.stop();
console.log(counter.toString());

// Stopwatch
var stopwatch = new bench.Stopwatch('forLoopDuration');
stopwatch.start();
for (var i = 0; i < 100; ++i)
  ;
stopwatch.stop();
console.log(stopwatch.toString());

// Timestampable
var rpc = new bench.Timestampable('rpc');
rpc.timestamp('received');
rpc.timestamp('processed');
rpc.timestamp('replied');
console.log(rpc.toString());

API

bench.counters

bench.stopwatches

bench.timestampables

Use the instances collection to ease your application from passing them around.

bench.counters.forLoopCounter.incr();
bench.counters['forLoopCounter'].incr();

Counter(name)

counter.decr([value])

counter.incr([value])

Default value is 1.

counter.start()

counter.stop()

Use start/stop in case you also want to know how long the counter is couting.

counter.reset()

counter.toString()

Stopwatch(name)

stopwatch.start()

stopwatch.stop()

It is cumulative elapsed time from each start/stop cycle.

stopwatch.reset()

stopwatch.toString()

Timestampable(name)

timestampable.timestamp(event)

timestampable.reset()

timestampable.toString()

The output will be like:

[timestampable rpc received=0ms processed=0.010993ms replied=0.013843ms]

Which the first event will always be 0ms, following events will have time difference from the first event.
