A simple time-series counter aggregation/syndication library for node backed by Redis and nothing else. Ideal for keeping track of counts between several processes.
npm install ssss
Note that you need a Redis version 2.0.0 or higher.
// Import and create instance
var SSSS = require('ssss'),
requests = new SSSS('requests');
// Simulate requests
(reqs = function() {
requests.ping();
setTimeout(reqs, 1000 * Math.random());
})();
// Output current average every
setInterval(function() {
requests.avgPerMinute(function (err, count) {
console.log(count, 'requests per minute');
});
}, 10000);Copyright 2014 John Sanderson
