External check problem

[bobrivers]

Hi,

I'm trying to use an external check to verify JMX parameters. I'm using jmxclient in order to do it.

I've build a script like this:

/usr/lib/jvm/java/bin/java -jar /home/zabbix/jmxclient.jar usr: pass host: port $1 2>&1 | awk -F: '{print $NF}'

If I execute the script manually (as zabbix user) it will run like a charm:

./jmx.sh java.lang:type=Threading\ ThreadCount

So, I created a new item in zabbix:

Description:ThreadCount
Type: External check
Key: jmx.sh[java.lang:type=Threading\ ThreadCount]

The script is being called, but I'm receiving an error from jmxclient: Key properties cannot be empty

This error occurs when jmxclient isn't supplied with a mbean to query.

So, I'm guessing that my item isn't properly configured.

What is wrong with my item?

TIA,

Bob

Hi,

Reading the manual helped a lot...

The external check will "append" an extra parameter even if you don't especify it. From zabbix manual:

Execute script check_oracle.sh with parameters ”-h 192.168.1.4”: (check_oracle.sh[-h 192.168.1.4]). Zabbix will execute: check_oracle.sh www1.company.com -h 192.168.1.4.

So I changed my script. Instead of use $1, I'm using $2 since I don't need the hostname...
