SMART by Zabbix agent 2 Issue

[Gomo]

So whats happening there is that the "zabbix" user is trying to execute the smartctl command which is a root privledged command only. The above suggestion from Markku should work for you on your machine. Typically what this means is that your zabbix system was not granted access to the /dev/sd? devices application. If his example does *not* work, then the problem is going to be in your /etc/sudoers file (either there is a hidden typo, located in the wrong order, etc.

Additionally, I see you used the "@includedir" function. If your sudo is 1.9.1 or earlier, that wont work and would need to be the original "#includedir" to get your zabbix entry.

Lastly, you have "two" zabbix entries, one in the include dir and one at the end of your /etc/sudoers file. You have to eliminate one of those or you have a conflict.

Here's the output:

As for the two zabbix entries, the one which was getting included via "@includedir" was removed soon after it was made.

I made sure all the formatting & potential double-spaces are removed from "zabbix ALL=(ALL) NOPASSWD:/usr/sbin/smartctl" entry in "visudo" but nothing is changing.
I am really not doing anything out of the ordinary here and it's quite frustrating that this template isn't working. There's too little variables to make a mistake on (compared to some other setup-ups) and yet it doesn't work :/

Hi!
I've the same issue and it's a problem due to the agent, as i can see into the debug log:

So I' think the problem is related to the proxy/server

What do you mean the issue is related to the "proxy/server" ?

[Markku]

Gomo maybe you could increase the agent logging as well and see what you get in the agent log when attempting?

[Gomo]

Exact same problem is documented here https://support.zabbix.com/browse/ZB...lugin%20(N)%22
I am really wondering how everyone is unaware / unaffected by this.

Unfortunately, following the suggested workaround in post mentioned above, leads to another error: "Cannot fetch data.: failed to scan for devices: Cannot unmarshal JSON.: invalid character '/' looking for beginning of value."

Hi, my template "SMART by Zabbix agent 2" is empty, without any items set by default. Can you help me understand how I can get the template with all the information?

[Markku]

The template is not empty, it has a discovery rule that will create the items.

Thanks for your help, I'm new to using this template, please help me solve my problem.

I am using the SMART template in Zabbix connected to a virtual machine with a 64-bit Windows 10 operating system.
I have installed and configured the Zabbix 2 agent and everything works correctly, without problems, however when I connect the "SMART by Zabbix agent 2" template the data is not transmitted and therefore I cannot carry out monitoring.
I installed the "smartmontools" program on the Windows VM but even with this it does not seem to detect data. If I run the command "smartctl.exe -a /dev/sda" in cmd I can see all the data on the physical disk correctly.

I also saw this guide https://www.zabbix.com/forum/zabbix-...hdd-smart-data and I tried to perform these steps but without success, I always get an error

[claros]

What do you mean the issue is related to the "proxy/server" ?

The agent itself read the data, but the proxy is unable to get/understand it. It's just a guess of mine anyway...

Hi, thanks for your suggestion. I solved this problem in another case
