How add an external check to zabbix?

[dga]

Hi,

SebD, I tried to activate an external check by taking exactly the script you mentionned at the beginning of this topic and doing what you did and it doesn't work, I always get "External check [check_apache.sh[]] is not supported" (I use "check_apache.sh[]" for the key and choose "text" for return type). I use the same version of Zabbix server as yours (1.4.1).

By the way, I guess external checks are mostly used to monitor network available resources from Zabbix server. If you want to monitor things like apache procs, built-in or user-defined Zabbix agent type checks would be more appropriate.

Hello dga!

Ok thanks!
That's what I've finally done : use Zabbix agent and configure zabbix_agentd.conf as you can see in my new post

But do you have an idea why I can't use external checks? Must I modify any other parameter than ExternalScripts in zabbix_server.conf?

Not relying on the agent for everything is very important to me so external checks must work if I am to use Zabbix in a production environment. As for simple checks , I think they are too basic and should be completely removed.

I find it strange that it's what appears in the zabbix_server.log even though I selected "external check":

Parameter [check_apache.sh[]] is not supported by agent on host [ZABBIX Server] Old status [0]

I solved my problem, thanks to spage in this topic:

SebD, You have 1.4.1 and you said you put "[]" and it worked..? I installed 1.4.1 from the tar.gz available from the main site and I had to put "()" and modify defines.inc.php as said in the topic above.

Hello dga!

Yes, [] work only when it's on the same computer, not for distant server.

This is not quote true. ZABBIX 1.4.1 processes () just fine, the only problem is that () are not accepted by the front-end.

ok! it's effectively the reverse... i've inverted my think with my saying...

[fableman]

using: zabbix-1.4-3

I tried everything and I cant get external scripts thats on my zabbix server to work towards external host that dont have a zabbix agent running.

What is wrong ?



# Location of external scripts

It is working...

Hi

I've just added two external checks yesterday, and they worked as they should:

1. I've created the files in /etc/zabbix/externalscripts
2. Chmodded them with +x
3. Added them in Zabbix like "ntpcheck[]" ie.

It is working as it's supposed to. The script ntpcheck looks like this (I prefer to do things in PHP):

#!/usr/bin/php
<?
        // Check for required parameters
        if($_SERVER["argv"][1])
        {
                $ntp_server = $_SERVER["argv"][1];
        } else {
                echo "You need to supply a NTP server to check. Quitting.\n";
                exit;
        }

        // Do query
        $query = exec("ntpdate -q -t 0.1 ".$ntp_server, $output, $return);

        if($return == 0)
        {
                echo "1\n";
        } else {
                echo "0\n";
        }
?>

It would help if you could show what scripts you are using, and how you have added it in zabbix.

Problem with parameters



I am using zabbix-1.4.2-2.fc6

I have a script alredy located in /etc/zabbix/externalscripts/ with 0755 as mode. It's a perl script that has this syntax:
script param1 param2

param1 and param2 are mandatory.


If you don't issue any parameters, script show right usage (as many commands in Linux)

(FYI script lists via snmp switch ports used by each vlan and *works properly* if I run out of zabbix)

Well, I went to Configuration of Items and added:
Description: upSnmpGet
Type: External Check
Key: upSnmpGet["10.1.0.4 vlanList"]

10.1.0.4 being parameter 1 and vlanList being parameter 2.

I saved and external check is added successfully but however I get:

usage: /etc/zabbix/externalscripts/upSnmpGet deviceAddress object

Please could you tell me if I Have something wrong in this config?

Thanks in advance!

hostname and more than one line

Hi,
I fixed partially the problem, I changed the switch name by his IP (an argument mandatory for the external script) and now it outputs "something", I mean, only one line, not the full output. I've tried with Character, Log and Text in type but it didn't worked.

Any ideas?

Thanks in advance!

please explain that a bit better ?

you changed the switch's name ? what switch ? you mean key ? trigger ?

[sebelk]

I changed a Network switch name in Configuration of Hosts. I am not talking about of key nor trigger, I'm talk about of items as I stated in a earlier post.

Thanks in advance
