Logstash not importing data - elasticsearch

Question

I am working on an ELK stack setup I want to import data from a csv file from my PC to elasticsearch via logstash. Elasticsearch and Kibana is working properly.
Here is my logstash.conf file:
input {
file {
path => "C:/Users/aron/Desktop/es/archive/weapons.csv"
start_position => "beginning"
sincedb_path => "NUL"
}
}
filter {
csv {
separator => ","
columns => ["name", "type", "country"]
}
}
output {
elasticsearch {
hosts => ["http://localhost:9200/"]
index => "weapons"
document_type => "ww2_weapon"
}
stdout {}
}
And a sample row data from my .csv file looks like this:
Name
Type
Country
10.5 cm Kanone 17
Field Gun
Germany
German characters are all showing up.
I am running logstash via: logstash.bat -f path/to/logstash.conf
It starts working but it freezes and becomes unresponsive along the way, here is a screenshot of stdout
In kibana, it created the index and imported 2 documents but the data is all messed up. What am I doing wrong?

Answer 1

If your task is only to import that CSV you better use the file upload in Kibana.
Should be available under the following link (for Kibana > v8):
<your Kibana domain>/app/home#/tutorial_directory/fileDataViz
Logstash is used if you want to do this job on a regular basis with new files coming in over time.

Answer 2

You can try with below one. It is running perfectly on my machine.
input {
file {
path => "path/filename.csv"
start_position => "beginning"
sincedb_path => "NULL"
}
}
filter {
csv {
separator => ","
columns => ["field1","field2",...]
}
}
output {
stdout { codec => rubydebug }
elasticsearch {
hosts => "https://localhost:9200"
user => "username" ------> if any
password => "password" ------> if any
index => "indexname"
document_type => "doc_type"
}
}
