Ackee Node Monitor Module

Ackee Node Monitor Module collects request and response data and sends this information using winston-elasticsearch to collector Elasticsearch defined in configuration file. Ackee Node Monitor Module sends request to collector once per timeout specified in config and only if at least one request is in collection.

Installation

# Install from npm
npm install ackee-node-monitor-module --save

Usage

First add Ackee Node Monitor Module configuration into config.js:

  • disabled: enable or disable logging
  • excludedUrls: urls excluded from logging, e.g. assets, css or js files ...
  • elastic:
    • host: specify url of Elasticsearch
    • log: log level (debug, info, trace, error)
  • winston:
    • level: log level (silly, debug, verbose, info, warn, error)
    • indexPrefix: the prefix used to generate the index name according to the pattern indexPrefix-[YYYY.MM.DD]
    • timeout: flushInterval - distance between bulk writes in ms, default: 2000
  • customHeaders: array of request custom headers logged to Elastic
  • customResponseHeaders: array of response custom headers logged to Elastic
  • customReqData: array of custom request data logged to Elastic
  • customPayload: custom payload logged to Elastic

Events

Ackee Node Monitor Module listens for close event and finish event:

  • close: Indicates that the underlying connection was terminated before response.end().
  • finish: Emitted when the response has been sent.

Example

module.exports = {
    ...
    ackeeNodeMonitor: {
            disabled: false,
            excludedUrls: ['/bower_components/', '/img/', '/js/', '/css/'],
            elastic: {
                host: 'someelastic.com:9200',
                log: 'trace',
            },
            winston: {
                level: 'silly',
                indexPrefix: 'nodetemplate-monitor',
                timeout: 10000
            },
            customHeaders: [
                'User-Agent'
            ],
            customReqData: [
                {
                    path: 'user',
                    name: 'user'
                },
                {
                    path: 'body.user.id',
                    name: 'userId'
                },
            ],
            customPayload: {
                appName: 'appName',
                appEnv: 'appEnv'
            },
        }
    ...
}

then require and init Ackee Node Monitor Module in server.js before calling createServer (app.listen(port);):

...
const express = require('express');
const config = require('config');

// require and init ackee-node-monitor-module
require('ackee-node-monitor-module')(config.ackeeNodeMonitor);

const app = express();
...
const server = app.listen(port);

Console output
