I have created sample.conf file for reading json file but it is not showing any output.
below is my sample.cong file
```auto
input {
file {
path => "C:\Users\Sagar\sample.json"
start_position => "beginning"
codec => "json"
}
}
filter{
json {
source => "message"
}
}
output {
stdout {
codec => json
}
}
```
below is my json file, it is contains just one value for testing purpose:
```auto
{"nativeId": 1001}
```
Below is logstash log:
```auto
C:\Users\Sagar\ELK\logstash-7.9.1>.\bin\logstash.bat -f .\config\sample.conf

- I have tried with `path => "C:/Users/Sagar/sample.json"` but is not working.
- converted file to .txt but it is not working.
- added `mode => read` it is not working
everytime i have deleted data folder and try different approach but not working.

Hi @sagarpatel
Most likely Logstash has already read the file once Logstash keeps track and so will not read it again... No matter how many times you run it. This is a common mistake when getting started
During debug and test you should probably set see [here](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-file.html#plugins-inputs-file-sincedb_path)
`sincedb_path => "/dev/null"`
In the file input section.
Or you can erase the since DB data every time but the` /dev/null` setting is easier
Also you don't need the multilpe json parsing... For a file with ndjson take it out of the json codec in the file input and just use the json filter.
In the output the just use the rubydebug
```
output {
stdout { codec => rubydebug }
}
```

I have tried below configuration as i am running logstash 7.9.1 on **windows**. But it is still not printing anything on log or prompt. one more thing i have noticed that [logstash 7.9.1 download page](https://www.elastic.co/downloads/past-releases/logstash-7-9-1) not showing OS based download link, that means is it supporting only Linux ? because i can see OS based [download for 7.10.x version](https://www.elastic.co/downloads/past-releases/logstash-7-10-0).
```auto
input {
file {
path => "C:/Users/Sagar/sample.txt"
start_position => "beginning"
sincedb_path => "NUL"
}
}
filter{
json {
source => "message"
}
}
output {
stdout { codec => rubydebug }
}
```

Can you post your Logstash output again to see if anything changed?

@sagarpatel
To answer your question Yes Logstash 7.9 is supported on Windows Server 2016 and Windows Server 2019.
How are you starting logstash?
and as @aaron-nimocks asked can you please post your logstash output?
There is something basic going on... like a typo in the path perhaps... the config about should just read the file... is there more than 1 line in the file?
