Logstash error(no data ) while ingesting CSV data with ELK version 8.9.2

[raemonx (Himangshu Shekhar Baruah)]

I was facing an issue while ingesting an csv file called housing_price_data.csv using logstash. I was using ELK with docker. I was using ELK version 8.11 I did not want to add any security so there is no SSL, passwords or any certificates involved in my file. All my containers elasticsearch, kibana and logstash are active and healthy(green) .I have attached my logstash.conf down below:

input {
  file {
    path => "/logstash_dir/housing_price_data.csv"
    start_position => "beginning"
    sincedb_path => "/dev/null"
  }
}

filter {
  csv {
    separator => ","
    columns => ["SquareFeet","Bedrooms","Bathrooms","Neighborhood","YearBuilt","Price"]    target => "housing_data"
  }
}

output {
  elasticsearch {
    index => "housing_data"
    hosts => ["http://es01:9200"]
    

  }
  #stdout {codec => rubydebug}

}

I keep getting the following error/problem down below(No data is read from the csv file):

I cannot pin point the mistake?

There is no error in the logs you shared, you need to check your source file.

First, does your logstash container have access to the /logstash_dir you shared?

Second, what does the housing_price_data.csv file looks like? Does it have more than one line?

Check does your user which runs LS have permission to read housing_price_data.csv
