Home PC Monitoring

This is a simple project that that uploads metriics from my PC and Rasberry PI to my Grafana account.

Rasberry Pi Host

This will be the device that will collect the metrics of other devices in the network to upload them to Grafana.com.

I use the following docker-compose.yml file:

version: "3.8"

services:
  grafana-agent:
    image: grafana/agent:v0.32.0
    volumes:
      - /tmp/agent:/etc/agent
      - ./agent.yaml:/etc/agent-config/agent.yaml
      - /var/log/:/var/log/
    command: -config.file=/etc/agent-config/agent.yaml -config.expand-env
    env_file:
      - ./auth.env
    restart: always

  rpi-exporter:
    image: carlosedp/arm_exporter
    restart: always

Note

At the moment of writing this, 0.32.0 was the latest Docker image version that was compatible with armv7.

On that same directory, we need a auth.env file with the following:

PROMETHEUS_USER=12345678
API_KEY=dGhpcyBpcyBub3QgYW4gYWN0dWFsIEFQSSBrZXk=

These values are all obtained from your account in Grafana.com.

Additionally, we have the configuration file for the agent:

integrations:
  node_exporter:
    enabled: false
  prometheus_remote_write:
    - basic_auth:
        password: ${API_KEY}
        username: ${PROMETHEUS_USER}
      url: https://prometheus-us-central1.grafana.net/api/prom/push


metrics:
  configs:
    - name: integrations
      remote_write:
        - basic_auth:
            password: ${API_KEY}
            username: ${PROMETHEUS_USER}
          url: https://prometheus-us-central1.grafana.net/api/prom/push
      scrape_configs:
        - job_name: rpi-exporter
          static_configs:
            - targets:
              - rpi-exporter:9243
        - job_name: <job-name-for-pc-job>
          static_configs:
            - targets:
              - 192.168.1.1:4445 # OhmGraphite
              - 192.168.1.1:9182 # windows_exporter

Windows Devices

On Windows devices, I use two tools:

OhmGraphite

This collects hardware sensor data, such as CPU and GPU temperatures. I use it in Prometheus mode

windows_exporter

Collects general information from Windows machine, similar to node_exporter.

Raspberry Pi Devices

Configuration for additional Raspberry PI devices coming soon.
