Description

This connector enables the monitoring of environment sensors on Linux, through the sensors command.

Target

Typical platform: Any system

Operating system: Linux

Prerequisites

Leverages: lm_sensors

Technology and protocols: Command Lines

This connector requires advanced privileges on the managed host for the commands below:

• /usr/sbin/dmidecode
• /usr/bin/sensors

This connector therefore needs to run as root or you need to configure a privilege-escalation mechanism like sudo on the managed host to allow the monitoring account to run the commands listed above.

Sample of /etc/sudoers to allow the above commands to be run as root by the metricshub account:

metricshub ALL=(root) NOPASSWD: /usr/sbin/dmidecode
metricshub ALL=(root) NOPASSWD: /usr/bin/sensors

Examples

metricshub HOSTNAME -t linux -c +lmsensors --ssh -u USER --sudo-command-list /usr/sbin/dmidecode,/usr/bin/sensors

resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: linux
        connectors: [ +lmsensors ] # Optional, to load only this connector
        protocols:
          ssh:
            username: <USERNAME> # Change with actual credentials
            password: <PASSWORD> # Encrypted using metricshub-encrypt
            useSudo: true
            useSudoCommands: [ "/usr/sbin/dmidecode", "/usr/bin/sensors" ]

Connector Activation Criteria

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

• Operating System is Linux
• The command below succeeds on the monitored host
  • Command: /usr/bin/sensors -h
  • Output contains: Usage: sensors (regex)
