Running the TICK Stack on a Raspberry Pi
Running the TICK Stack on a Raspberry Pi
Introduction
The TICK Stack (Telegraf, InfluxDB, Chronograf, and Kapacitor) is a powerful suite of open-source tools for collecting, storing, visualizing, and analyzing time-series data. Running the TICK Stack on a Raspberry Pi enables a lightweight yet robust monitoring system for IoT devices, smart home projects, or small-scale system monitoring.

This guide will walk you through installing, configuring, and running the TICK Stack on a Raspberry Pi.
Prerequisites
Hardware Requirements:
- Raspberry Pi 3, 4, or newer (Recommended: Raspberry Pi 4 with at least 2GB RAM)
- MicroSD card (16GB or more)
- Stable internet connection
- Raspberry Pi OS (64-bit recommended)
Software Requirements:
- Raspberry Pi OS (Debian-based, preferably 64-bit)
- InfluxDB, Telegraf, Chronograf, and Kapacitor
- SSH access (optional but recommended)
Step 1: Update and Prepare Raspberry Pi
Before installing the TICK Stack, ensure your system is up to date:
sudo apt update && sudo apt upgrade -y
Install essential utilities:
sudo apt install wget curl git -y
Step 2: Install InfluxDB
InfluxDB is the time-series database for storing sensor data.
1. Add the InfluxData repository:
wget -qO- https://repos.influxdata.com/influxdb.key | sudo apt-key add -
echo "deb https://repos.influxdata.com/debian stable main" | sudo tee /etc/apt/sources.list.d/influxdb.list
2. Install InfluxDB:
sudo apt update && sudo apt install influxdb -y
3. Start and enable InfluxDB:
sudo systemctl start influxdb
sudo systemctl enable influxdb
4. Verify the installation:
influx -version
Step 3: Install Telegraf
Telegraf is used to collect system and sensor metrics.
1. Install Telegraf:
sudo apt install telegraf -y
2. Configure Telegraf:
Edit the configuration file to collect system metrics:
sudo nano /etc/telegraf/telegraf.conf
Set the output plugin to InfluxDB:
[[outputs.influxdb]]
urls = ["http://localhost:8086"]
database = "telegraf"
3. Start and enable Telegraf:
sudo systemctl start telegraf
sudo systemctl enable telegraf
4. Verify data collection:
tail -f /var/log/telegraf/telegraf.log
Step 4: Install Chronograf
Chronograf is the web-based UI for visualizing data stored in InfluxDB.
1. Install Chronograf:
sudo apt install chronograf -y
2. Start and enable Chronograf:
sudo systemctl start chronograf
sudo systemctl enable chronograf
3. Access the Chronograf Web UI:
Open a browser and go to:
http://<RaspberryPi_IP>:8888
Step 5: Install Kapacitor
Kapacitor is used for real-time alerting and event processing.
1. Install Kapacitor:
sudo apt install kapacitor -y
2. Start and enable Kapacitor:
sudo systemctl start kapacitor
sudo systemctl enable kapacitor
3. Verify Kapacitor:
kapacitor show tasks
Step 6: Configure TICK Stack
Create a Database in InfluxDB:
influx
CREATE DATABASE telegraf;
SHOW DATABASES;
Configure Telegraf to Send Data:
Ensure the telegraf.conf file is correctly set to store data in the telegraf database.
Enable Alerts in Kapacitor:
Edit the Kapacitor configuration file:
sudo nano /etc/kapacitor/kapacitor.conf
Define alert rules using TICKscript.
Restart All Services:
sudo systemctl restart influxdb telegraf chronograf kapacitor
Step 7: Visualizing Data
1. Open Chronograf:
Visit:
http://<RaspberryPi_IP>:8888
2. Connect to InfluxDB:
- Enter
http://localhost:8086 - Select the
telegrafdatabase - Build dashboards and graphs
3. Set Up Alerts in Kapacitor:
- Use TICKscript to define alerts
- Integrate with Slack, Email, or Webhooks
Conclusion
Running the TICK Stack on a Raspberry Pi is a great way to build a lightweight IoT monitoring system or home automation dashboard. This setup enables real-time data collection, visualization, and alerting with minimal hardware requirements.
With InfluxDB storing time-series data, Telegraf collecting metrics, Chronograf providing visualization, and Kapacitor handling alerts, you now have a complete monitoring solution on a compact device!
