Logstash logging

Hi!

I was wondering if there is any location that stores the logs in Logstash before sending it to any destination? and if there, where and how can I find it?

Thanks.

You can use PQ or debug mode to see what's happening inside the processing.

yes I know, but what I want to know is if there is any location that saves the logs in logstash, this is due to space constraints in logstash server
