lighthouse lightkeeper performance-monitoring

Lightkeeper is a simple lighthouse job orchestrator made with nodejs.

Launches lighthouse audits against a list of url for selected profiles at specified frequency.
Stores generated reports until specified retention period limit
Extracts results data from reports and stores selected values to results.log
Embeded webserver allows to access reports and logs (https and basic-auth )

How to use it ?

Run with CLI

Prerequisites

Install Chrome or Chromium
Install Lighthouse

npm install -g lighthouse

Install this package

npm install -g lighthouse-orchestrator

Run

# generate default configuration
lightkeeper --init-config

# run it
lightkeeper

Available arguments :

--config-dir : Directory containing your config files, default is current directory. See below for configuration details.
--data-dir : Directory for output storage, defaults to ./data. See below for output details.
--init-config : Writes default configuration to "config-dir" path so you can adapt them to your needs.
--init-profiles : Writes default lighthouse profiles to "config-dir" path so you can adapt them to your needs.

Run with Docker

Prerequisites

clone lighthouse-orchestrator repository

git clone [email protected]:GGracieux/lighthouse-orchestrator.git

build dockerfile

docker build -t lightkeeper .

Create a docker-compose.yml specifying config-dir and data-dir folders (see below for configuration and output details). For example :

version: '3.2'
services:
  lightkeeper:
    image: lightkeeper
    volumes:
      - /tmp/conf:/lightkeeper/conf:rw
      - /tmp/data:/lightkeeper/data:rw
    ports:
      - 8086:80

Run

docker-compose up

Configuration

All configuration files must be located under the config-dir passed as command argument. A set of example configurations are available under /examples :

jobs.json

This file defines the jobs to run with lighthouse. Each job must specify the following properties :

url : the url to run
profiles : the list of profiles to run the test with, see below for profile configuration
cron : the frequency at wich test should be run. Notation is like cron with seconds granularity.

Additional properties can be added, they can be writent to result log according to result log configuration.

If your config-dir does not have a jobs.json file, lightkeeper uses it's default (see /default-conf/jobs.json)

For example the following jobs.json file runs :

https://www.example.com with mobile configuration every 30 minutes
https://www.google.com with mobile and desktop configuration every hour

        {
            "url":"https://www.example.com",
            "profiles":[ "mobile"],
            "cron": "1 */30 * * * *"
        },
        {
            "url":"https://www.google.com",
            "profiles":[ "mobile", "desktop"],
            "cron": "1 1 */1 * * *"
        }

lightkeeper.json

This file defines the general execution parameters of lighkeeper. Lightkeeper loads it's default configuration (see /default-conf/lightkeeper.json) and then overloads it with your custom lightkeeper.json file located under config-dir folder.

The following lightkeeper.json file is the default configuration :

{
    "reports":{
        "formats": ["html"],
        "retentionDays": 7
    },

    "logs":{
        "lightkeeper":{

The profile.xxxxx.json files are lighthouse configuration files. The xxxxx filename part defines the profile name which you can use in jobs.json.

You can add as many profile as you want based on lighthouse configuration format

Lightkeeper comes with two default profiles, mobile and desktop, they are identical to lr-desktop-config.js and lr-mobile-config.js

You can add new profiles by writing profile.xxxx.json files under config-dir. You can overwrite default mobile and desktop files by writing profile.mobile.json and profile.desktop.json under config-dir.

Outputs

Every data produced by lightkeeper is stored under the data-dir passed as command argument. According to lightkeeper.json, the data-dir folder can be exposed through http.
