Use can e.g. use different file inputs that each assign different types and then you can use conditionals to apply different filters and outputs to each kind of file.

So what happens? What does an example event look like when Logstash is done with it? Use a `stdout { codec => rubydebug }` output.

It looks like you're not closing the filter block before you begin your output block. Also, you're not closing your output block.

Please find the below config file and correct if anything wrong

input  
{  
file  
{  
path =\> "/tmp/AWSDiscoverynew.csv"  
start\_position =\> "beginning"  
}  
file

}  
}  
filter {  
if [path] == "/tmp/AWSDiscoverynew.csv"  
{  
csv {  
columns =\> ["A","B","C","D"]  
separator =\> ","  
}  
}  
}  
else if [path] == "/tmp/AWSDiscoveryTest.csv" or [path] == "/tmp/AWSDiscoverytest2.csv"  
}  
{  
csv {  
columns =\> ["A","B","C","D","E","F","G"]

The `hosts` option in your elasticsearch output is obviously incorrect but otherwise it should work. However, having this kind of direct dependencies to filenames is a bad idea. Prefer setting the type or some other field in each file input and adjust your conditionals.

You have too many braces before `else if [path]`.
