Grafana setup on Raspberry-Pi

The main objective of this README is to provide a guide on setting up Grafana on a Raspberry Pi. It includes installation steps, server startup, configuration of Grafana, adding a connection for JSON, and configuring the Grafana.ini file.

1. Installation
2. Grafana configuration

1. Installation

Step 0: Connect with shh remote connection from your local machine to the Raspberry Pi

export HOSTNAME=192.168.178.69
export REMOTE_USER=pi
ssh ${REMOTE_USER}@${HOSTNAME}

Step 1: Follow the steps in the Grafana documentation to install Grafana on Raspberry-Pi

Step 2: Extract how to start the server

sudo /bin/systemctl enable grafana-server

sudo /bin/systemctl start grafana-server

sudo shutdown -r now 

2. Grafana configuration

Step 1: Open Grafana

export HOSTNAME=192.168.178.69
open http://${HOSTNAME}:3000

Step 2: Change the password

Login with admin/admin.

Step 3: Add a connection for JSON

Select JSON.

Step 4: Select install

3. Grafana.ini configuration

Verify the Grafana.ini configuration to more options for an initial setup. One important topic is the time format configuration.

sudo nano /etc/grafana/grafana.ini

• Data format for the time:

# For information on what formatting patterns that are supported https://momentjs.com/docs/#/displayi>

# Default system date format used in time range picker and other places where full time is displayed
;full_date = YYYY-MM-DD HH:mm:ss

# Used by graph and other places where we only show small intervals
;interval_second = HH:mm:ss
;interval_minute = HH:mm
;interval_hour = MM/DD HH:mm
;interval_day = MM/DD
;interval_month = YYYY-MM
;interval_year = YYYY

4. (Optional) Add Raspberry Pi Monitoring

You can follow the steps in this article Raspberry Pi Monitoring
