How to check persistent queue draining?

Hi there,

we are (still) using ELK stack 5.4 in a very simple singlenode Docker-Compose setup with persistent queue enabled:

queue.type: persisted
path.queue: /usr/share/logstash/queue
queue.max_bytes: 5gb

After reading this I wanted to give it a try, added the queue.drain: true setting to the configuration and stopped/started the logstash (docker compose) service. Then I stopped the service again (so the new draining setting should work).

When checking the filesystem I noticed the page is still there with 250MB size. Is this normal behaviour? Is there a way to check if the draining actually worked or how many elements are currently stored in the persistent queue?

Thank you!
Jens

Can someone help me with this please?
