event handler not working

[Billy Liang]

Hello Eli,

Thanks for responding. I found out what's my problem.  I wasn't able to get 
any output when I remove dumping content to STDERR, but I was able to pipe 
the output to a file. At there I saw what's the problem.  Because the plugin 
output contains white space, i need to wrap it with double quotes to make it 
pass to the program as a single argument. Now it's working fine. Thanks for 
the suggestion.
