========================================================

I want to do the following things:

  1. Remove the multiple head lines until "File name, Folder...." this line.
  2. Remain "Machine name:..." this line.

Then import the CSV data. Due to there are many Windows clients need to collect.
So I want to implete the following:

  1. List top 10 Large files clients

====================================================

The following is my previous logstash config file.

input{
file{
path => "c:/report/file10.csv"
start_position => "beginning"
sincedb_path => "NULL"
}
}
filter{
csv {
separator => ","
columns => ["File name","Folder","Owner","Size on Disk","Size","Last accessed"]
}
if ([Comm_Plan] == "Comm_Plan")
{
drop { }
}

}

output{
elasticsearch{
hosts => "http://localhost:9200"
index => "filename10"
document_type => "sold_filename10"
}
stdout{}
}

Please help me to resolve it. Thanks a lot.
