hello everyone ,

my problem (it's not a real problem) is when i for example modify logstash config to creat a new index pattern and this new index it's concern files that already contained into certain folder before configuration of logstash , i always have to recharge files in this folder (i mean move files away then re input them in the folder ) , i am asking if there is a method to make logstash read file that already exist before it's config ?

thank you

It sounds like you're looking for the file input's `start_position` option. It controls what Logstash does with newly discovered files.

No, the file input plugin ships with Logstash.

It's an **input** plugin not a **filter**. Move it to the right section in your config file.
