TIG Stack using InfluxDB 3 Core

TIG Stack is an arconym for the following three open source technologoies that seamless work togther to collect, store, analyze and monitor real time data from almost anything such as servers, APIs, IoT devices or even your smart coffee machine!

1. Telegraf to collect system metrics
2. InfluxDB 3 Core (alpha release) as database for metrics
3. Grafana as data visualization in dashboard

Pre-requisite:

1. Docker should be installed on your local machine and make sure it's running.
2. Git (optional) to clone this Git Repository

Steps:

1. Clone the repository

git clone https://github.com/InfluxCommunity/TIG-Stack-using-InfluxDB-3-Core.git
cd TIG-Stack-using-InfluxDB-3-Core

2. Start the Stack

Make sure Docker is up and running by typing docker info. Once you verify it is then let's build our stack in background which is configured in the docker-compose.yaml. Feel free to edit it file as per your need.

docker-compose up -d

3. Verify metrics are being collected by Telegraf

docker-compose logs telegraf

4. Create InfluxDB Token & Update the .env file

docker-compose exec influxdb influxdb3 create token

Add to the .env file the bearer token

INFLUXDB_TOKEN=your_new_token_here

5. Verify InfluxDB is setup correctly and tables are being created

docker-compose logs influxdb
docker ps
docker exec <container-id> influxdb3 query --database local_system "SHOW TABLES"

6. Setup & View Grafana Dashboard

• Open localhost:3000 from your browser
• Login with credentials from .env (default: admin/admin)
• Add Data Source : InfluxDB at http://influxdb:8181
• Add Data Visualization : Dashboards > Create Dashboard - Add Visualization > Select Data Source > InfluxDB_3_Core
• In the query 'builder' paste and run the following SQL

SELECT "cpu", "usage_user", "time" FROM "cpu" WHERE "time" >= $__timeFrom AND "time" <= $__timeTo AND "cpu" = 'cpu0'

7. Stopping the TIG Stack & Removing Data

Stop Services

docker-compose down

Stop Services (careful!)

docker-compose down -v
