Empty String From Remote Command

[stammer]

Hi,

I'm having problems using remote command. The result is a empty string, but if I execute manually the script, it returns data.

Using zabbix_agentd it returns "OK", But using zabbix_get it returns an empty string:

In attachmment. I couldn't post code here because of live links/images validation.

Anyone could help me?

Hi stammer,

The user Zabbix on your Windows have the permission to launch your script ?

Hi stammer,

The user Zabbix on your Windows have the permission to launch your script ?

Hi, wick

Zabbix service use the same user as I have manually executed the commands.

[wick]

What do you do to prepare the script ?
We need to know how you configure your script execution by zabbix agent

sorry for my bad english

Hi,

All of the remote commands are failing. Remote Commands is enabled on zabbix agent configuration.

As simple ECHO become not supported:

system.run["echo Teste"]

[wick]

In your config file you do something like that for your script ?

https://www.zabbix.com/documentation/3.2/manual/config/items/userparameters

cause if it's not do you can create a directory next to your agent config file name "zabbix_agentd.d". After in this directory create a config file with

UserParameter=<key_you_want>,<the_path_of_your_scr ipt>

After restart your agent

and normaly it's good

[stammer]

Using the command "system.run" I don't need to use UserParameter.
I already have used this script in hundreds o servers, but only this specific server has this problem.

Problem with the firewall ? I don't know what doing wrong with this server ...

[stammer]

There are many servers behind the firewall.
If I run the command manually using zabbix_agentd it returns the correct value.
Only zabbix and if I run the command manually using zabbix_get it returns an empty string.

[wick]

I don't know what going wrong maybe you config file ? A commented file ?

Can you put your config file on pastebin please

https://pastebin.com/

if you can't for some reason i can understand so try to put config file of an other server on this server and try again.

Somebody can help?

[wick]

You try to uninstall the agent ? copy and paste an other fonctionnal config file in this server ? or just restart th service ?

[stammer]

I already have installed a more recent version of Zabbix.
Also I copied the config file from a functional config file.
I don't know what I can do more.

[wick]

Try to reinstall .. maybe a bad installation ? or ... i don't know too
just restart the service do not function ?

Or reinstall windows server ?
