Turris Omnia - Temperature sensors discovery

[Modrasek]

Hi,

First of all, I apologize for the bad English.

I would like to solve the following problem:

Let's have Zabbix Server version 5.0.3.

Next, let's have a Turris Omnia router. Zabbix Agent version 4.0.16 is installed on it.

After running the "sensors -j" command, Turris Omnia returns a list of temperature sensors and their values in the following JSON form:

{
"mv88e6xxx102-mdio-2":{
"Adapter": "MDIO adapter",
"temp1":{
"temp1_input": 49.000,
"temp1_crit": 100.000,
"temp1_max_alarm": 0.000
}
},
"mv88e6xxx100-mdio-0":{
"Adapter": "MDIO adapter",
"temp1":{
"temp1_input": 49.000,
"temp1_crit": 100.000,
"temp1_max_alarm": 0.000
}
},
"f1072004mdiomii01-mdio-1":{
"Adapter": "MDIO adapter",
"temp1":{
"temp1_input": 41.000,
"temp1_crit": 100.000,
"temp1_max_alarm": 0.000
}
},
"mv88e6xxx103-mdio-3":{
"Adapter": "MDIO adapter",
"temp1":{
"temp1_input": 49.000,
"temp1_crit": 100.000,
"temp1_max_alarm": 0.000
}
},
"mv88e6xxx101-mdio-1":{
"Adapter": "MDIO adapter",
"temp1":{
"temp1_input": 49.000,
"temp1_crit": 100.000,
"temp1_max_alarm": 0.000
}
},
"armada_thermal-virtual-0":{
"Adapter": "Virtual device",
"temp1":{
"temp1_input": 72.261
}
},
"mv88e6xxx104-mdio-4":{
"Adapter": "MDIO adapter",
"temp1":{
"temp1_input": 49.000,
"temp1_crit": 100.000,
"temp1_max_alarm": 0.000
}
}
}

I would like create a Discovery rule that, based on the discovered temperature sensors, creates Items whose:

• The names will correspond to the names of the temperature sensors (mv88e6xxx102-mdio-2, armada_thermal-virtual-0,...),
• The values will correspond to the temperatures from the given sensors (49.000, 72.261,...).

After carefully reading the official documentation, I still do not understand how I can achieve the desired goal.



I have created a template for Turris Omnia with the following Discovery rule:

• Name: Turris Omnia Sensors
• Type: Zabbix agent (in the file "zabbix_agentd.conf" I have the line "UserParameter=sensors
• ,sensors $1")
• Key: sensors[-j]

LLD macros:

• LLD macro {#SENSOR_NAME} ... JSONPath "$.*~" (without quotes)
• LLD macro {#SENSOR_TEMP} ... JSONPath "$.
• .['Temp1'].['Temp1_input']" (without quotes)

No Preprocessing, No Filters, No Overrides



I also created an Item prototype with attributes:

• Name: Sensor {#SENSOR_NAME}
• Type: Zabbix agent
• Key: sensors[{#SENSOR_NAME},{#SENSOR_TEMP}]
• Type of information: Numeric (float)
• Applications: Sensors
• Applications prototypes: Sensor {#SENSOR_NAME}

What's wrong, please, that no items are being created?

Thank you very much for your help.

Resolved even with triggers. I did not understand the input format of JSON for Discovery rules.
