node-stat-collector

Basic stat collection for Node.js web applications. Comes with Express.js middleware support.

Installation

npm install stat-collector

Available Tracking

  • Query Counts - saved to Redis
  • Response Times - pushed to Circonus

Only configured components will be enabled, allowing one to only track what is necessary.

Examples

Using Express.js Middleware

var express = require('express');
var StatCollector = require('StatCollector');

var statCollector = new StatCollector();
statCollector.setDebug(true); // Global debug logging (default false)

var queryCounterConfig = {
    redisConfig: { // Configuration options for node-redis
        host: 'localhost',
        port: 1234,
        options: {}
    },
    statPrefix: 'foo_', // Prefix for stat hashes in Redis (e.g. 'foo_' for foo_requestTotal)
    pushInterval: 30000, // Interval (ms) in which to update Redis (default 30000)
    debug: false // Debug logging (default false)
};

var responseTimerConfig = {
    circonusConfig: { // Circonus HTTP Trap check config
        host: 'foo',
        port: 1234,
        path: '/'
    },
    pushInterval: 500,  // Interval (ms) in which to push to Circonus (default 500)
    debug: false // Debug loging for this module (default false)
};

statCollector.configureQueryCounter(queryCounterConfig);
statCollector.configureResponseTimer(responseTimerConfig);

var app = express();

app.configure( function(){
    app.use(statCollector.middleware());
    app.use(app.router);
});

app.get('/foo',function(req,res){
    res.jsend('success',{'foo':'bar'});
});

app.listen(9000);
