Hey guys,  
I want to write a simple application that would help me debug my Logstash configurations.  
I find it pretty annoying to modify configuration files in my server and restarting the Logstash service each time I want to see how my changes affect the output.  
The best I came with is to run the logstash.bat with custom configuration file and make each configuration to output to a log file but this is still annoying because I need to restart it each time I make changes and it takes some time to load.  
This is OK but still not good enough, the best case would be to be able to run Logstash as a standalone tool like that -  
logstash\_stand\_alone.exe [config\_file] [input\_log\_file] [output\_log\_file]  
Any ideas?  
Thanks ahead 🙂

Does the --config.reload.automatic command line option help?
