Speedlog — back-end for performance tracking

Speedlog is a server that stores the performance log of third-party applications.

I developed speedlog to monitor the performance of the front-end. But you can use speedlog in any applications that can send REST requests.

Usage example speedlog + perfumejs + graphite

Speedlog may be a suitable back-end for storing data collected using perfume.js

Use the following docker-compose.yml file to start the speedlog server and graphite server.

Specify a random key in the parameter --jwtkey

version: '3'
services:
  app:
    image: khyurri/speedlog:0.1.9
    command: "/opt/speedlog/main
    --jwtkey=***
    --mongo=mongo:27017
    --alloworigin='*'
    --tz=\"Local\"
    --graphite=graphite:2003
    --project=myProject"
    depends_on:
      - mongo
      - graphite
    ports:
      - "8012:8012"
    restart: always
  mongo:
    image: mongo:3.6
  graphite:
    image: graphiteapp/graphite-statsd
    ports:
      - "8013:80"

After launch, 2 services will be publicly available on the host:

• speedlog. Port 8012
• graphite web interface. Port 8013

Connect perfume.js

To connect perfume.js to speedlog add the following code to the perfume initialization

var project = "myProject";
const perfume = new Perfume({
    firstPaint: true,
    analyticsTracker: (metricName, duration, browser) => {
        var xhr = new XMLHttpRequest();
        xhr.open('POST', 'http://127.0.0.1:8012/event/');
        xhr.setRequestHeader('Content-Type', 'application/json');
        xhr.send(JSON.stringify({
            "metricName": metricName,
            "durationMs": duration,
            "project": project
        }));
    }
});

Do not forget to replace IP 127.0.0.1 with a real host

Now you can open graphite in a browser at the address http: //127.0.0.1:8013 and build something like this

speedlog versions and Installation

Prior to version 1.0.0, I am actively developing speedlog, which means:

• API may change without maintaining backward compatibility
• documentation may not be true
• the new version may break something that worked before

The latest version is always available on dockerhub. Docker — my recommended way to install speedlog.

CLI

Modes

The first parameter to cli must be the mode of the speedlog. If mode is not passed, then speedlog starts in default mode: runserver

Available modes

Mode	Description
runserver	starts the server
adduser	adds user
addproject	adds project
delete	deletes user or project

Examples

Starting the server and creating the myProject project (if not created)

speedlog --jwtkey=*** --mongo=mongo:27017 --project=myProject"

User Creation

speedlog adduser --login=admin --password="-?sEcrE7-"

Starting the server with exporting data to graphite

speedlog --jwtkey=*** --mongo=mongo:27017 --graphite=graphite:2003

Project creation

speedlog addproject --project=myproject

Delete project

speedlog delete --project=myproject

Delete user

speedlog delete --login=admin

I need help translating documentation into English!
