How to check debug info for external script

[kitkit201]

Hello,

I created an external script and it seems to be working when i run it manually as a zabbix user, but I dont see any results on the html page that it is suppose to generate.

Here are the logs I am seeing

 28544:20140514:213301.325 In substitute_key_macros() data:'movieupload.sh[]'
 28544:20140514:213301.325 End of substitute_key_macros():SUCCEED data:'movieupload.sh[]'

By the logs, it seems like it is running, but again, i dont see any output.

Any help would be appreciative.

Thanks
Kit
