Is there a way in node.js to get the number of open connections and number of requests per second from a http server?
Assume the following simple server:
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end("Hello World!");
}).listen(80);
Thanks.
This is what I usually do when I want to double-check numbers ab/httperf/wrk/siege report:
var served = 0;
var concurrent = 0;
http.createServer(function (req, res) {
concurrent++;
res.writeHead(200, {'Content-Type': 'text/plain'});
setTimeout(function() { // emulate some async delay
served++;
concurrent--;
res.end("Hello World!");
}, 10);
}).listen(80);
setInterval(function() {
console.log('Requests per second:' + served);
console.log('Concurrent requests:' + concurrent);
served = 0;
}, 1000);
