How to enter data from csv to elasticsearch using logstash? - elasticsearch

Question

I am trying to insert data into elasticsearch using logstash but getting stuck. My config file:
logstashCrime.conf
input {
file {
path => "C:\elk\sampl.csv"
start_position => "beginning"
sincedb_path => "nul"
}
}
filter {
csv {
separator => ","
columns => ["code","name"]
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => "crime"
}
stdout {
codec => rubydebug
}
}
I am getting a response like this when I try to insert using logstash-7.2.0\bin\logstash -f c:\elk\logstashCrime.conf:
Thread.exclusive is deprecated, use Thread::Mutex
Sending Logstash logs to C:/elk/logstash-7.2.0/logs which is now configured via log4j2.properties

1,john
2,doe
3,you
4,me
I am new to ELK. Any help appreciated. Also, I am using windows 10 as my OS. I successfully created an index using logstash withoug csv, but with csv it is not creating.
I want to view it in Kibana but since the index is not created, I cant see the index in Kibana.

You cannot use backslash in the path option of a file input. Use forward slash.
