Hello Community,

iam very new in this topic. I start a windows service via nssm.exe to observe a file for a csv to start the logstash.bat and specified config.

Now i have the problem that after the logstash is triggered. The csv file is still in use. How can i close the csv file after logstash is finished with the csv. Second question is where, and did i need additional plugins?

Where: In Config file or in arguments via nssm.exe?

best regards

Bernd

If you are using a file input in tail mode then logstash will keep the file open and tail it forever. You may be able to use read mode. What does your configuration look like.

```auto

		start_position => "beginning"
		sincedb_path => "Q:/DATA/Test/Logstash/sincedb"
	}

	csv {
		separator => ";"
		skip_header => "true"
		columns => ["testdata1","testdata2","Date"]	
	}

	
	date {

		target => "Date"
	}
	
	
	
}
output {	
	elasticsearch {
        hosts => ["elastictest:9200"]
        index => "test"

OK, you are using tail mode, so logstash will keep the file open forever.
