Hi,

We are planning to use logstash in our project.  
I have 200 different files to be processed, and the files are updated every 15 minutes.  
My question is how many file filters can be used in input plugin?

input  
{  
file  
{  
  
}  
file  
{  
  
}  
.  
.  
.  
.  
file  
{  
\<file`n` descriptors\>  
}  
}

What is the approximate value of n that logstash can handle?

Regards,  
Sathish
