Q:

Not able to map csv file from logstash to kibana in Window

I'm trying to feed data in csv files into elastic search using logstash. My logsatsh config file looks like this:
input {
file {
path => "D:\Log Anlyser\data\cars.csv"
start_position => "beginning"
sincedb_path => "NUL"   
}
}
filter {
csv {
separator => ","
columns => [ "maker", "model", "mileage", "manufacture_year", "engine_displacement", "engine_power", "body_type", "color_slug", "stk_year", "transmission", "door_count", "seat_count", "fuel_type", "date_created", "date_last_seen", "price_eur" ]
}
mutate {convert => ["milage", "integer"] }
mutate {convert => ["price_eur", "float"] }
mutate {convert => ["engine_power", "integer"] }
mutate {convert => ["door_count", "integer"] }
mutate {convert => ["seat_count", "integer"] }  
}
output {
elasticsearch {
hosts => ["localhost:9200"]
index => ["cars-%{+YYYY.MM.dd}"]
}
}

while firing this command for logstash in window : logstash -f cars.conf i am getting this:-
Sending Logstash logs to D:/Log_Anlyser/logstash/logs which is now configured via log4j2.properties

Now While connecting to kibana(localhost:5601) i am not able to map the data. Getting this error:- 

Unable to fetch mapping. Do you have indices matching the pattern?
  Can you please help.

A:

I got the problem. Mistake is very silly. Path of CSV file was wrong. Earlier path   was path => "D:\Log Anlyser\data\cars.csv". Current Path is`

path => "D:/Log_Anlyser/data/cars.csv"

It will work
