No output in plugins


I downloaded check_ser plugins for checking SER. When I try to run it in terminal, it is successful though there’s no output. Its just goes back to prompt. When I miss some of the parametes, it shows an error so I concluded that if it goes back to prompt means no error.

But when I check the web interface, it says “no output”… Can this be a script problem?
I chmod /usr/local/nagios/ to 710 and chown -R nagios.apache /usr/local/nagios to make sure permission is correct

Here is the checkcommands.cfg

check_ser command definition

define command {
command_name check-sip
command_line $USER1$/check_ser -H $ARG1$ -U $ARG2$ -P $ARG3$ -w $ARG4$ -c $ARG5$

Here is the bigger.cfg

define service{
use generic-service
service_description SIP
check_command check-sip!!!xyz123!50!80
