Install with npm:
npm install --save acumulus
var accum = acumulus().max_samples(5 * 60).sample_interval(1000);From here on out, you can simply start accumulating (using 5 samples to make it easy to see what's going on):
// Add one
accum.add("foo");
// Wait four seconds
accum.add("foo", 5);
accum.add("bar");Now we can use it:
accum.get("foo"); //=> 5
accum.series("foo"); //=> [1, 0, 0, 0, 5]
accum.sum("foo"); //=> 6
accum.sum_all(); //=> [{series: "foo", value: 6}, {series: "bar", value: 1}]
accum.top(1); //=> [{series: "foo", value: 6}]Wait another couple seconds:
accum.series("foo"); //=> [0, 0, 5, 0, 0]From the repo root:
