Help to configure User Parameter

[Bastien]

Hi,

I try to use UserParameter in order to monitor some host.

The UserParameter will execute a shell script and return a value. I wrote this following sentence in the host's zabbix_agentd.conf :

"UserParameter=check_glsa,/etc/zabbix/externalscripts/check_glsa"

I already put the script in the good directory with the right permission.

I configure an Item on the Zabbix server like this :

Host : Template_Linux_myHost (my host is in this template)
Description : GLSA
Type : Zabbix Agent (Active)
key : check_glsa

I didn't have real error, however the value returned is bad, indeed in "latest data" the value GLSA is different that when a execute the script in my host. It's the value of my Zabbix Server..

Plz someone can help me to resolve the problem..

asantana:
There are a few things that you should check/do.
If your zabbix agent is running under the zabbix user, then you should ensure that the zabbix user has privileges to use `du` and that it can access that folder. Like I had issues with the Zabbix agent being unable to run `lsof -p <process id>`due to permissions.
Secondly, it is best if you can use an absolute path for `du`, eg. `/usr/bin/du`.

To find the absolute path for `du`, run `which du`.

To simply check if zabbix user can run that command, run the following:
su zabbix -c 'du /home/aner/Desktop/test/ -cbxs | grep total | cut -f1'

Like my zabbix_agentd.conf would look like this:

UserParameter=test,/usr/bin/du /usr/src/zabbix-1.8.13/ -cbxs | grep total | cut -f1

As a last resort, you can look for errors in your Zabbix server logfile.
