zabbix-sensors not executed

[nagylzs]

I have installed zabbix-sensors ( https://github.com/blind-oracle/zabbix-sensors ) on a zabbix agent. /etc/zabbix/zabbix_agentd.d/sensors.conf contains this line:

UserParameter=lmsensors.discover[*],/etc/zabbix/scripts/sensors.py $1

This file is included from /etc/zabbix/zabbix_agent.conf:

Include=/etc/zabbix/zabbix_agentd.d/*.conf


The lm-sensors package was installed correctly. The zabbix agent runs as user "zabbix". I can see that JSON data is exported when I run this:

sudo -u zabbix /etc/zabbix/scripts/sensors.py

Results in something like this:


[
{
"{#ADAPTER}": "k10temp-pci-00c3",
"{#TYPE}": "TEMP",
"{#NAME}": "Tdie",
"{#MIN}": 0.0,

"{#MIN}": 0.0,
"{#HIGH}": 95.0,
"{#CRIT}": 105.0,

}
]

I can also get actucal sensor values, for example:

# sudo -u zabbix sensors -u | grep fan1
fan1:
fan1_input: 3630.000


Next thing I did is that I have imported the zabbix-sensors template to zabbix server, and assigned this template to the given host. I can see that lmsensor discovery rules appeared in the host configuration.

Then I restart the zabbix-agentd service, and I see this in the logs:

There are no errors. Everything seems to be fine. Except for the fact that "Latest data" does not show any data from sensors.

The discovery interval is 1h, and I have been running this host for at least a day.

What am I doing wrong?

Hallo nagylzs,

did you find any solution?

I have got exactly the same issue. Only coretemp-isa-0000 works correctly, but not the other one. Zabbix agent detects all properly by script (sensor.py), but afterwards requests to the sensor are rejected.


zabbix_get -s solo -k sensor["coretemp-isa-0000","temp2"]
49.000000

# zabbix_get -s solo -k sensor["acpitz-acpi-0","temp1"]
ZBX_NOTSUPPORTED: Cannot obtain sensor information.


Here are my sensor devices

soc_dts1-virtual-0
Adapter: Virtual device
DTS 1: +47.0°C

acpitz-acpi-0
Adapter: ACPI interface
ACPI 0: +46.6°C (crit = +100.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +49.0°C (high = +90.0°C, crit = +90.0°C)
Core 1: +49.0°C (high = +90.0°C, crit = +90.0°C)
Core 2: +48.0°C (high = +90.0°C, crit = +90.0°C)
Core 3: +49.0°C (high = +90.0°C, crit = +90.0°C)

axp288_fuel_gauge-isa-0000
Adapter: ISA adapter
Vcore 0: 4.49 V
curr1: 0.00 A

soc_dts0-virtual-0
Adapter: Virtual device
DTS 0: +49.0°C

Any suggestions?

In the meanwhile I went this way. witch worked out.

UserParameter=system.cpu.temperature.sockel,sensor s | grep "ACPI 0" | awk -F'[:+°]' '{print $3}'
UserParameter=system.cpu.temperature.dts0,sensors | grep "DTS 0" | awk -F'[:+°]' '{print $3}'
UserParameter=system.cpu.temperature.dts1,sensors | grep "DTS 1" | awk -F'[:+°]' '{print $3}'
UserParameter=system.cpu.temperature.core0,sensors | grep "Core 0" | awk -F'[:+°]' '{print $3}'
UserParameter=system.cpu.temperature.core1,sensors | grep "Core 1" | awk -F'[:+°]' '{print $3}'
UserParameter=system.cpu.temperature.core2,sensors | grep "Core 2" | awk -F'[:+°]' '{print $3}'
UserParameter=system.cpu.temperature.core3,sensors | grep "Core 3" | awk -F'[:+°]' '{print $3}'



Tnx in advance ThW

Hi ThW and nagylzs

I'm having the same exact problem:

python3 /etc/zabbix/scripts/sensors.py
{
"hwmon0-i350bb": {
"temp1": {
"crit": 110000,
"input": 75000,
"label": "loc1",
"max": 120000,
"sensor_type": "temp"
}
},
...

1211711:20240326:112757.299 agent #6 started [active checks #2]


everything seems to work fine except that the template is not returning values.
I also tried directly add the UserParameter directly into the /etc/zabbix/zabbix_agentd.conf with no success.

Any suggestions? Could this be becouse the package im using to run the zabbix-agent is the one that comes with linstor/ceph installation?

Thanks

Hello again, I have managed to fix this. It was wrong permissions in my case:

[root@zabbix-server ~]# tail -f /var/log/zabbix/zabbix_server.log
1. Failed: SyntaxError: invalid json (at offset 1)
at [anon] (duktape.c:37568) internal

1707:20240327:144326.301 discovery rule "srv-prox1-dc:sensors.discovery.voltage" became not supported: Preprocessing failed for: sh: 1: /etc/zabbix/scripts/sensors.py: Permission denied


I managed to fix it doing:
chmod +x /etc/zabbix/scripts/sensors.py
chown zabbix:zabbix /etc/zabbix/scripts/sensors.py
systemctl restart zabbix-agent2
