Permissions problem with custom script in UserParameter Zabbix 3.2.11

[nuv]

Hello,

i have following problem when im trying to add custom item in zabbix.

I created two custom items:

/etc/zabbix/zabbix_agentd.conf
UserParameter=used,/etc/zabbix/xen-used-space.sh
UserParameter=total,/etc/zabbix/xen-total-space.sh

Permissions for those scripts are (0755/-rwxr-xr-x)

visudo:
zabbix ALL=(root) NOPASSWD: /etc/zabbix/xen-used-space.sh
zabbix ALL=(root) NOPASSWD: /etc/zabbix/xen-total-space.sh

# zabbix_agentd -t total
total [t|136.113]

Error from zabbix server: Item not supported - Timeout while executing a shell script.

When i trying to run those scripts with zabbix user:

# sudo -u zabbix /etc/zabbix/xen-used-space.sh
Authentication failed
For usage run: 'xe help'
Authentication failed
For usage run: 'xe help'

/etc/zabbix/xen-total-space.sh

#!/bin/bash

used(){
    xe sr-param-list uuid=`xe sr-list params=uuid name-label="Local storage" --minimal` | grep physical-size | awk '{print $4}' | awk '{ byte =$1 /1024/1024/1024; print byte }'
}

echo "$(used)"

Any ideas?
