Hello, I'm new to the list, I need your your help to solve this problem.
Ojectif: Automatically update the div with live stats We have a website for online ads, this site shows you the number of live connected, ad views etc ... until today I did a setInterval which launched a jquery function to update the div. This all works well, only problem that consumes unnecessary connections. And comes nodejs, great tool .. except it kills the server. (probably because I use it wrong) Here's how I do it: The client side: <script type="text/javascript" src="http://10.0.0.10:1337/socket.io.js "></script> <script type="text/javascript"> (function ($) { if (typeof (io) != "undefined") { var socket = io.connect("http://10.0.0.10:1337/socket.io.js";); setInterval(function () { socket.emit("cron_showcompteur", { ssid: "*SSID_ID*", id_website: 1 }); }, 5 * 1000); socket.on("showinfo", function (obj) { $("#" + obj.divdest).html(obj.result); }); } })(jQuery); The client initiates the socket every 5 seconds to cron_showcompteur with its SSID. Server side: .. var initConf = require('./conf'); var http = require('http'); var util = require('util'); var os = require('os'); var Memcached = require('memcached'); var memcached = new Memcached(util.format('%s:%s', initConf.objConf.memcache_ip, initConf.objConf.memcache_port)); .... io.sockets.on('connection', function (socket) { socket.on('cron_showcompteur', function (obj) { var loadAvg = os.loadavg(); if (typeof (obj.ssid) == 'undefined') return; socket.join(obj.ssid) if (loadAvg[0] < 3) { memcached.get(["nombre_visite_journee", util.format('annonces_ajoutees_journee_%d', obj.id_website)], function (err, result) { if (err) return; if (typeof (result) == 'boolean') return; for (var i in result) { io.sockets. in (obj.ssid).emit('showinfo', { divdest: i, result: addCommas(result[i]) }); } }); } }); }); In summary: The person connects to the site, sending its SSID it with his ID website Once initialized nodejs socket created a room with its SSID, every 5 seconds the client asks the stats and nodejs sending the result in the div using the "showinfo" This works great when you're 600/700 connected to cons up to 1000 as soon as the server (a server dedicated to nodejs) CPU rises to 100%, the result of anything the site works no longer able to initialize the nodejs socket on the server and site plant. I tested several variants: - Put the setInterval server side, it is worse. - From fonctioner to trigger as soon as a client connects or opens an ad that charging other etc .... Memeched stats are updated on the PHP I have a doubt about the cons made ??that we need to create a user-room, it seems big ... because the data are not private. I would like to avoid the long-pooling, I like the idea of ??the socket. Could you advise me a method to automatically update the DIV on all wireless clients that do not crash the server?
