Creating alert with bash exit code

[yatta]

Hi,
I'm trying to create a basic alert regarding to a command's exit code.

Command is just greps output of a script;

"Item" is like below;

#!/bin/bash
echo {$SSH.USER.PASSWORD} | sudo -S sh /script/linux_check.sh | grep "Down"

So if the command catches "down", exit code is = 0

And the trigger expression is like below;

last(/linux_instance_check.sh/ssh.run[cmd1.command])=0

But it's not creating alert.

Is the trigger expression should be something else?

Thanks!

echo $? solved the problem!

Hi,
I have some another problem, it seems Zabbix creates fake alerts as I understand.

I created an SSH Item with the command below;

  #!/bin/bash
  echo {$SSH.USER.PASSWORD} | sudo -S sh /script/linux_check.sh | grep "Down" | echo $?

And if I run this command on the server manually, output is 1, that means there is no "Down" text on the output.

And I created a trigger like below;



So if the output is other than 0, no alert should be created but Zabbix creates the alert!

Any idea why?
