Why zabbix is looking for a bad path to execute my external script.

[Clayzes]

Hello,
I'm trying to monitor cpu temperature using https://github.com/blind-oracle/zabbix-sensors

So I did everything but in the ui I have the error



my sensors.conf

So why is zabbix trying to use /externalscripts ?

Thank you for your help

I suspect you have somekind of misconfiguration in your item. Can you show item config screenshot?
Externalscripts parameter exists only in Server/proxy config, so maybe your item type is wrong? "External check" instead of "zabbix agent" ?

Hello,
Sorry for delay

Not the same item, your first pic shows an items with a name containing "voltage" or "disco.."... Nothing like that on your last pic... And dependent item will not execute any script ...

Item prototypes:

Sensors Json item



from template_sensors

So here you are, as I predicted... you are using "external check" type of item. This is something, that is executed on server/proxy and looked up from that /usr/lib/zabbix/externalscripts directory by default...
If you define a user parameter, then you need to use "Zabbix agent" or "Zabbix agent (active)" as userparameters are executed by agent. external check is not userparameter...
Or move that sensors.py script to /usr/lib/zabbix/externalscripts directory...

Same error even with the script on the right directory and external check ON.

Verify script access rights... "namei -mo /usr/lib/zabbix/externalscripts/sensors" . It has to be accessible by user "zabbix"

[Clayzes]

Yes it's accessible by Zabbix , I tried to sudo -u as Zabbix to execute the script and it worked

I'm late to this party, but I don't understand why you're so intent on trying to use this as an "External check" item type.

Perhaps you know something about those scripts that I do not, but based upon the documentation in the github repo you linked, those scripts work by accessing files in the sys pseudo filesystem. If that is correct, then the "sensors" script would need to be run on the host that you want to monitor. If you run it as an "External check" from a proxy, you're going to get the sensors for the proxy, not for any system that reports to the proxy.

There *are* ways to get sensor data remotely (via IPMI or some other lights-out management protocol like Dell's iDRAC), but at least based upon the documentation, that is not how "sensors" works.

Hello,

The "External check" item is set from the template on the repo , I did not set it.
Which item type do you think I should use here ?

[cyber]

I just downloaded and installed it on my test zabbix... this installs 1 item and 4 discoveries. And that one item IS of type "Zabbix agent". Definitely not "external check". And it uses Userparameter in agent. which is exactly as tim.mooney mentioned... So yes.. change it to "Zabbix agent" (or "active"), add userparameter to agent config and enjoy those sensors from that host...

That external check threw me off a lot.. Should have checked right away by downloading..

[tim.mooney]

You diagnosed the problem correctly on your first response. It would have taken me a lot longer to figure out that it was the item type.

oh ok , Im gonna take a look , thank you
