Zabbix Extrenal Scripts

[spage]

Hi

When i define an External Script using the PHP Front end it will not except script('value') It will only except script['value'] Which Returns "External check [script['value']] is not supported"

I've update the frontends/php/includes/defines.inc.php

FYI Syntax of external checks was changed in pre 1.4.2:

script[arguments]

Both frontend and server side were updated.

Hi,

Im getting issues when using external scripts. here are the details:

Value on the item:

test.sh [-h 127.0.0.1]

basically the script only does counting of messages inside the mail queue.

the file is located inside /etc/zabbix/externalscript/ which the owner from zabbix folder down is user zabbix and group zabbix. permission is set to 755

here is what i see on the log:

hope you can assist me on this issue.

thank you.

Did you set 'ExternalScripts=/etc/zabbix/externalscripts' in zabbix_server.conf ?

If you "su - zabbix" can you run the script ?

Does it output return value on stdout as
value\n
?

Item should be named scriptname.sh[args...] (no space).

[Silvery]

You cannot use it like this: test.sh [-h 127.0.0.1]

The script awaits a list of parameters between the squared brackets, separated by spaces. The option -h is something you have to set inside of your script.

So for test.sh[127.0.0.1] your script should look like this:

#!/bin/bash

HOST="$1" -->The Host, where you link this script is always $1
VARIABLE="$2" -->In your case: $2 = 127.0.0.1

`bash-command -h $VARIABLE`

I see. Can I use the test.sh without [127.0.0.1] ? all i want is to run the script.

[Silvery]

Sure, if you want to use the parameter 127.0.0.1 by default you can use it in your script like this:

`bash-command -h 127.0.0.1`

then you can call the script without any parameters: test.sh[]

But I don't know if 127.0.0.1 will work. Why don't you use the public IP address of the host in place of the loopback IP address?

The new shell script will return the value 0 if its successful and 1 if it fails. All I want to happen is to zabbix execute the script, get the value (0 or 1) and put that value on a graph or alert. I tried manually executing the shell script as user zabbix inside externalscripts directory and it works fine. Not sure what to do next here. Additional suggestions are much appreciated.

Thank you.
