How add an external check to zabbix?

[SebD]

Hello,

I work with Zabbix 1.4.1 and I wrote an external check (I know Zabbix have his own apache check, but I d'like to do this by myself) :

#!/bin/sh
################################################## ################
# ce script retourne l'état du process apache
################################################## ################

STATE_OK=0
STATE_WARNING=1
STATE_CRITICAL=2
STATE_UNKNOWN=3
STATE_DEPENDENT=4

# récupération de l'état du process httpd apache
# STATE = état de sortie du process en sortie du grep
ps auxw | grep httpd | grep -v nagios >> /dev/null
STATE=$?

# Vérification de l'état du process
if [ "$STATE" = "$STATE_OK" ]
then
date >> toto_apache
echo "PROCESS APACHE EST OK" >> toto_apache
echo "" >> toto_apache
echo "PROCESS APACHE EST OK"
exit 0
else
date >> toto_apache
echo "PROCESS APACHE NE FONCTIONNE PAS" >> toto_apache
echo "PROCESS APACHE NE FONCTIONNE PAS"
exit $STATE_CRITICAL
fi

Someone could tell me where I must save my script and how I have to install in Zabbix please? I couldn't understand how make the link between Zabbix and my script!

Thanks!

Sébastien

I'm in the same case as you, I would like to write a check_service_dns plugin, but I don't know where to put it????

Thanks

Hi Sebastien,

1. create an /etc/zabbix/externalscripts directory with correct rights
2. copy your script to this directory, suppose your script name is testhttpd.sh
3. on zabbix web interface, create an item with type "External Check" and key is testhttpd.sh

Note that if you have an agent on the server, an alternative solution is to create an userParameter

Hello Jean Pierre,

I tried what you explained to me, but I've got "External check [check_apache.sh] is not supported "

I've put the following rights : chmod 755 and chown zabbix to the externalscripts directory and the scripts inside.

I've create an item with "external check" and "check_apache" in the key.

Have you any idea where comes this problem from?

I've also try my script with UserParameter as you said and it works!

Thanks

Sébastien

What version of Zabbix ?

Hi Sebastien,

What version of Zabbix do you use ? I use 1.4 (from rBuilder iso).

Note that the script must be on the Zabbix server, not on the agent !

I'm using 1.4.1 version from source.
I've put the script on the Zabbix server.

The externalscripts directory doesn't be declared anywhere in the config of zabbix_server?

ExternalScripts

Hi,

Use the parameter ExternalScripts=yourpath on your zabbix_server.conf
Make sure your file has read and execute access for all users ...
See zabbix_server.log to view the error message.

Jean Pierre,

In first, thanks for your help!

So I've the following rights to /etc/zabbix (where I put /etc/zabbix/externalscripts) :

chown -R zabbix.zabbix /etc/zabbix/
chmod -R 777 /etc/zabbix/

I've added in zabbix_server.conf :
ExternalScripts=/etc/zabbix/externalscripts/

I've restarted zabbix_server and put active my external check, but I always have "External check [checkApache.sh] is not supported ".

In the zabbix_server.log, I can only find for this problem :
"29439:20070725:114214 Parameter [checkApache.sh] is not supported by agent on host [ServerName] Old status [0]"

Hello!

Is there anybody who have an idea where's could come from my problem?

There's nobody else who have tried the external check?

[cadbury]

same problem here,

i did what is on the manual, and what is here, but same error than you.

going to use the good old agent with userparameter on my zabbix server ...

[lance242]

I'm also seeing this problem ...

Nothing more to add to the thread other than another person seeing this issue (be it doc or a real issue).

External scripts MUST have [] ( or (), see my note below). For example:

check_apache.sh[] - no parameters (apart of hostname) are passed to the script

check_apache.sh[params] or check_apache.sh["params"] - hostname and parameters "params" are passed to the script

This syntax is for pre 1.4.2 and later releases only! Earlier releases accept () instead of []. Sorry for the change of syntax within one major release...

[mcarbonneaux]

it's a bug in 1.4.2... the ui check for "()" and the zabbix server check for "[]"...

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

Hello!

Ok thanks Alexei for your soluce!
I've put [] and it's running except for a distant host :
The externals checks are on the computer where is Zabbix Server.
When the Zabbix call an externel check for a distant host, it ran it on the same computer as Zabbix and not on the host.
I've tried to add to my external check "rsh -l" before the command, but it doesn't want to run too!
