HI,  
I am collecting files with Logstash and sending them to an Elasticsearch database.  
But I'm running into the problem that I can't pick up the date that file was created or last modified. I'm working on Linux, and what I need is to know how to extract this field and send it to elastic.  
I have tried all sorts of filters in ruby ​​but end up seeing "%{data}" and not the output. There is a way to get this correctly?

Hello @AlejandroVindel,

Welcome to the community!

Check if this [config](https://discuss.elastic.co/t/how-can-i-set-current-time-in-field/157542/3) makes sense for your use case.

Hope it helps!

Are you reading files by FB or LS?

If this doesn't help what Priscilla suggest, can you provide a sample, what you want?
