init scrp of zabbix agent ackges do not show any error if misctakes are happened..

by exampl i enable script directory and no put any script .. o agen could start..
but if i launch init script that not show the error:

sysmonitor:~# /etc/init.d/zabbix-agent start
Starting Zabbix agent: zabbix_agentdsysmonitor:~#

note the no new line when try to start
i modify the "> /dev/null 2&1" part by removing and for see wht happened and got :

sysmonitor:~# /etc/init.d/zabbix-agent start
Starting Zabbix agent: zabbix_agentdzabbix_agentd [30232]: /etc/zabbix/zabbix_agentd.conf.d/: [2] No such file or directory
sysmonitor:~#

so then:

Theres any possibility to improve this script to show what happened if any mistake are happened?
