Front Basic RUM GO

Introduction

This is a simple application server written on Golang. The server receives payloads (beacons) sent from visitors who are browsing websites. The payload data that is being sent is collected and packaged by a JavaScript library called Boomerang JS. The main purpose of Boomerang JS is to collect performance related data from web pages.

Below is a simplified diagram of how the data flows for our use case:

Data flow

This project focuses on the component Basic RUM GO but this is how the data flows in the completed system that contains various components for data persistency and visualization:

  1. GET/POST request is sent from a browser to our application server. The application server does some transformation of the received data.

  2. The transformed data is being persisted to a database called ClickHouse.

  3. Charts and other visualizations are being created while Grafana is querying ClickHouse.

How to start dev environment

1. Start ClickHouse

Run:

make up
2. Start Front Basic RUM GO

2.1 Set environment variables

# server
export BRUM_SERVER_HOST="localhost"
export BRUM_SERVER_PORT=8087

# database
export BRUM_DATABASE_HOST="localhost"
export BRUM_DATABASE_PORT=9000
export BRUM_DATABASE_NAME="default"
export BRUM_DATABASE_USERNAME="default"
export BRUM_DATABASE_PASSWORD=""
## optional
export BRUM_DATABASE_TABLE_PREFIX=""

# persistance
## optional
BRUM_PERSISTANCE_DATABASE_STRATEGY=""
## optional
BRUM_PERSISTANCE_TABLE_STRATEGY=""

# backup
## optional - default false
BRUM_BACKUP_ENABLED=true
## optional. required if BACKUP_ENABLED=true
BRUM_BACKUP_DIRECTORY=""
## optional
BRUM_BACKUP_INTERVAL_SECONDS=0

2.1.1 If you want to use SSL with custom files

# server
export BRUM_SERVER_HOST="localhost"
export BRUM_SERVER_PORT=443
export BRUM_SERVER_SSL=true
export BRUM_SERVER_SSL_TYPE=FILE
export BRUM_SERVER_SSL_CERT_FILE=domain.crt
export BRUM_SERVER_SSL_KEY_FILE=domain.key

2.1.2 If you want to use SSL with Let's encrypt

2.1.2.1 http server is started

# server
export BRUM_SERVER_HOST="localhost"
export BRUM_SERVER_PORT=8087

2.1.2.2 https server is started (port: 443)

# server
export BRUM_SERVER_SSL=true
export BRUM_SERVER_SSL_TYPE=LETS_ENCRYPT
export BRUM_SERVER_SSL_LETS_ENCRYPT_DOMAIN=domain.com

Note: To verify that you’re the owner of domain for which you want a certificate, Let’s Encrypt server calls back your server. For that to work, DNS name must resolve to the IP address of your server.

2.2 Start Front Basic RUM GO

go run main.go

2.3 Application creates table on startup with following structure### 3.

3. Table is automatically created in ClickHouse

You can check that the table is created with required structure by following the steps below.

3.1 Load http://localhost:8143/ in your browser

3.2 Check a table is created:

5. Query the test data

5.1 Load the ClickHouse dev user interface

Load http://localhost:8143/ in your browser

5.2 Query the data

Run the follwoing query:

SELECT * from webperf_rum_events
6. Running the server

Start:

./main > app.log 2>&1 &

Periodically check the app.log file for any interesting messages

Check if the server is running:

netstat -ltnp | grep -w ':8087'

Stop the server:

kill -9 $(lsof -i:8087 -t)
