On this post I will explain how I set up a Grafana + Prometheus into a RaspberryPi with Raspbian.
Here it’s a little design where explains how it is the implementation I did:
🔵 Server: RaspberryPi 3B+
- Services to install(server side):
- Grafana
- Prometheus (Metric collector and database)
- Node Exporter (collector worker)
🟢 Clients: Raspberrypi Zero Fedora Workstation Debian VPS
- Services to install(client side):
- Node Exporter (collector worker).
🔵 Lets start from the server side.
- Installing Prometheus.
NOTE: please go to the download section and pick up the right model of your processor. In my case is armv7
$ wget https://github.com/prometheus/prometheus/releases/download/v2.22.0/prometheus-2.22.0.linux-armv7.tar.gz
$ tar xfz prometheus-2.24.0.linux-armv7.tar.gz
$ rm prometheus-2.24.0.linux-armv7.tar.gz
$ mv prometheus-2.24.0.linux-armv7 prometheus
Create the service [systemd]
$ sudo nano /etc/systemd/system/prometheus.service
Into the service we have:
[Unit]
Description=Prometheus Server
Documentation=https://prometheus.io/docs/introduction/overview/
After=network-online.target
[Service]
User=pi
ExecStart=/usr/local/bin/prometheus/prometheus \
--config.file=/usr/local/bin/prometheus/prometheus.yml \
--storage.tsdb.path=/usr/local/bin/prometheus/data \
--web.enable-admin-api \
--web.listen-address=:9090
[Install]
WantedBy=multi-user.target
Keep on mind the “prometheus.yml” file it’s where we need to config our prometheus
$ sudo systemctl daemon-reload
$ sudo systemctl enable prometheus.service
$ sudo systemctl start prometheus.service
- Installing Node Export
