LM Sensors - Linux

Tutorial aimed at enabling the LM Sensors package on Linux distributions for monitoring through Monsta.

Install and configure the LM Sensors package

Logged in as root, on the screen of the Linux server to be monitored run the command below:
• For distributions that use yum:

yum install lm_sensors

• For distributions that use apt-get

apt-get install lm_sensors

After the package is installed, run the command below to detect the sensors present on your server and write the lm-sensors configuration file:

sensors-detect --auto

After sensor detection finishes, you can display the available items and their readings on the console using the sensors command, as in the example below:

Install the SNMP service

See our tutorial at Configuring SNMP on Linux.

Monsta

To monitor the sensors in Monsta, during device creation add the “LM Sensors” template as shown in the example below. This way, when adding a monitor in Monsta the monitors related to LM Sensors will also be shown.
