LM-sensors Zabbix Template

Template for monitoring Intel / AMD Architecture x86 or x64 temperature with Zabbix.

Prerequisites

• System is linux and command for sensors is sensors -u (Debian, Ubuntu...)
• You need to have installed sensors on your linux system.
• Your system architecture need to be x86 (32b) or x86_x64 (64b)
• Python3 installed
• Zabbix Agent installed (tested with Zabbix Agent 2)

Install process

Create a scripts directory on your agent config

mkdir /etc/zabbix/scripts

Copy Python script to the new directory

cp zbix-lmsensors.py /etc/zabbix/scripts/zbix-lmsensors.py
chmod +x /etc/zabbix/scripts/zbix-lmsensors.py

Copy config file to agent config folder

cp zbix-lmsensors.conf /etc/zabbix/zabbix_agent2.d

Restart agent

systemctl restart zabbix-agent2.service

Last steps

Import template on your Zabbix and assign the template to the machine where you installed the script and config.

Test

In the machine, on shell execute the command

/usr/bin/python3 -B /etc/zabbix/scripts/zbix-lmsensors.py

Check the results. For an Intel i5 10500T the output is

[
  {
    "core_id": 0,
    "core_temp_now": 60,
    "core_temp_high": 80,
    "core_temp_critical": 100,
    "socket": 0,
    "index": 0
  },
  {
    "core_id": 1,
    "core_temp_now": 55,
    "core_temp_high": 80,
    "core_temp_critical": 100,
    "socket": 0,
    "index": 1
  },
  {
    "core_id": 2,
    "core_temp_now": 54,
    "core_temp_high": 80,
    "core_temp_critical": 100,
    "socket": 0,
    "index": 2
  },
  {
    "core_id": 3,
    "core_temp_now": 55,
    "core_temp_high": 80,
    "core_temp_critical": 100,
    "socket": 0,
    "index": 3
  },
  {
    "core_id": 4,
    "core_temp_now": 54,
    "core_temp_high": 80,
    "core_temp_critical": 100,
    "socket": 0,
    "index": 4
  },
  {
    "core_id": 5,
    "core_temp_now": 55.85,
    "core_temp_high": 65261.85,
    "core_temp_critical": 94.85,
    "socket": 0,
    "index": 5
  }
]

Some CPU have the same value for HIGH and CRITICAL temp, so if you want to force another temps you can pass this parameters

Parameter	Required	Description
--set-high-temp	Optional	Set the value for HIGH temp
--set-critical-temp	Optional	Set the value for CRITICAL temp

/usr/bin/python3 -B /etc/zabbix/scripts/zbix-lmsensors.py --set-high-temp 70 --set-critical-temp 95

Will overwrite the json output.

    "core_temp_high": 70,
    "core_temp_critical": 95,

  },
  {
    "core_id": 1,
    "core_temp_now": 60,

  },
  {

    "core_temp_high": 70,

  },
  {
    "core_id": 3,
    "core_temp_now": 59,
    "core_temp_high": 70,
    "core_temp_critical": 95,
    "socket": 0,
    "index": 3
  },
  {
    "core_id": 4,
    "core_temp_now": 64,
    "core_temp_high": 70,
    "core_temp_critical": 95,
    "socket": 0,
    "index": 4
  },
  {
    "core_id": 5,
    "core_temp_now": 57.85,
    "core_temp_high": 70,
    "core_temp_critical": 95,
    "socket": 0,
    "index": 5
  }
]

The script doesn't check if the high value is greater than critical, or if some of them is negative value... So it's in your hand to set a good values. Zabbix will use this fields to set the trigger thresholds.

Template

The template comes with one item and one discovery rule.

Prototype Items

• CPU Socket X Core Y Temperature

Prototype Triggers

CPU {#INDEX} temperature equal or greater than {#TEMP_HIGH}ºC

When the temperature reaches the high value. This trigger has dependency on the next.

CPU {#INDEX} temperature equal or greater than {#TEMP_CRITICAL}ºC

When the temperature reaches the critical value
