Running sample text file thorough logstash

This is my sample file

FName,Lname,sal,location
Suresh,Koganti,6000,Montreal
Denis,Gallagher,7000,Quebec

and this is my conf file

input {

file{

    path => "C:\Users\skkoganti\Documents\log\users.txt"

    start_position => "beginning"

}

}

filter {

    text{

autodetect_column_names => true

}

}

output {

stdout {

codec => rubydebug

}

}

i am getting the below error.

If you specify -e it will not use the configuration file.

I cannot imagine why you would get that error with that command line.

Do not use backslash in the path option of a file input, it is treated as an escape. Use / instead.

Thanks for quick reply,

i am getting the same error again.

No, that is a different message. It is not finding the file.

I am getting the different error this time

You are loading a non-existent filter. In your first post you had

filter {
    text{
        autodetect_column_names => true
    }
}

Did you mean that to be csv?

No, i am actually running the txt file. Later i changed on conf file as per my requirement.

input {

file{

    path => "C:/Users/skkoganti/Documents/log/users.txt"

    start_position => "beginning"

}

}

filter {

    txt{

        separator => ","

        columns => ["FName","Lname","sal","location"]

        autodetect_column_names => true

}

mutate {convert => ["FName", "string"]}

mutate {convert => ["Lname", "string"]}  

mutate {convert => ["sal", "integer"]} 

mutate {convert => ["location", "string"]} 

}

output {

stdout {

codec => rubydebug

}

}

There is no such thing as a txt filter. It looks like you are trying to configure a csv filter. The name of the filter is based on its functionality. It has nothing to do with the name of the file that you are reading.

Thanks Badger,

I don't know how to read sample text file but i want to read my log files which my ETL tool is generating log files. at least i need to test txt file through logstash.

Please help me on this or if you sample conf file please share me.

Thanks,
Suresh Koganti.
