ZBX_NOTSUPPORTED: Unsupported item key.

[islem karoui]

Hello,

I've recently installed zabbix server and agent version-2.4.5 on a RedHat system (Red Hat Enterprise Linux Server release 6.5). This machine contains several filesystems.
I installed zabbix on one of them using installation from sources (./configure --prefix=/installation/directory, make, make install prefix=/installation/directory).

I have both of the server and agent working (showing green Z availability icon).

My problem is with user parameter, it doesn't work.

I added this one in the zabbix_agentd.conf file:

UserParameter=sortby.cpu,/bin/ps aux | /bin/sort -nk +3 | /usr/bin/tail | /usr/bin/tr -s " " | /bin/cut -d " " -f 3,11

(I had to specify the path for every command, because they are in different locations)

when I execute zabbix_get, I get Unsupported item key result:

/zabbix/bin> ./zabbix_get -s 172.17.15.169 -p 10050 -k sortby.cpu
ZBX_NOTSUPPORTED: Unsupported item key.

But when I execute this :
/zabbix/sbin> ./zabbix_agentd -t sortby.cpu

sortby.cpu [t|3.3 RTSDGN
3.5 java
3.5 RTSDGN
3.6 RTSDGN
3.7 /etc/alternatives/jre_1.7.0/bin/java
3.7 /etc/alternatives/jre_1.7.0/bin/java
5.2 /etc/alternatives/jre_1.7.0/bin/java
6.3 /etc/alternatives/jre_1.7.0/bin/java
9.0 /bin/ps

It gives a result.

I configured the item "sortby.cpu" on the zabbix frontend as following:

Name: sortby.cpu
Type: Zabbix agent
Key: sortby.cpu
Type of information: Text
Applications: General
Enabled: yes

I am confused now, why do I get Unsupported item key then ?

[Atsushi]

Did you make a restart of the agent after setting add?

[islem karoui]

yes I did

Do I need to tell him on which filesystem to execute the user parameter?
because there is several filesystems on the machine.

If this doesn't work, what can I use as an other alternative to get the same result ?
