UserParameter one more time

[tbi]

Hello,
i have a problem with my UserParameter in zabbix_agentd.
I use the following command:

UserParameter=raid.online,megacli -PDList -aAll | egrep "state: Online" | wc -l

i test my parameter

[root@ ~]# /usr/local/zabbix/sbin/zabbix_agentd -t raid.online
raid.online [t|4]

but in zabbix_agentd.log on client side I received 0 [i was expecting 4]

14811:20120604:121338.505 Run remote command [megacli -PDList -aAll | egrep "state: Online" | wc -l] Result [1] [0]...
14811:20120604:121338.505 Sending back [0]

also when i try to run zabbix_get it gets 0:

[root@ ~]# zabbix_get -s 10.192.64.2 -k raid.online
0

can anybody could help me to resolve these problems?

userparameter runs as "zabbix" user, not root (unless you forced the agent to run as root), maybe the "zabbix" user doesn't have permission to run the "megacli" executable? try running the command as the "zabbix" user on the machine and check the output

hi,
you were right. zabbix doesn't have permission to run this command.
thanks.
