Raspberry Pi Hardware

Description

Monitors the Raspberry Pi board (model and serial number), its CPU temperature and, when the kernel exposes a tachometer, the cooling fan speed in RPM.

hardware linux raspberry-pi

Target

Typical platform: Raspberry Pi

Operating system: Linux

Prerequisites

Leverages: Linux device tree, thermal and hwmon sysfs interfaces

Technology and protocols: Commands

Examples

CLI

metricshub HOSTNAME -t linux -c +Rpi --ssh -u USER

metricshub.yaml

resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: linux
        connectors: [ +Rpi ] # Optional, to load only this connector
        protocols:
          ssh:
            username: <USERNAME> # Change with actual credentials
            password: <PASSWORD> # Encrypted using metricshub-encrypt

Connector Activation Criteria

The Raspberry Pi Hardware connector will be automatically activated, and its status will be reported as OK if all the below criteria are met:

• The command below succeeds on the monitored host:
  • Command: test -r /sys/firmware/devicetree/base/model && tr -d '\000' < /sys/firmware/devicetree/base/model
  • Output contains: ^Raspberry Pi (regex)
