Clear Logstash cache

Elastic Stack Logstash
1

Hello.
How can I clear Logstash cache? I got new data from Windows event log but I just see old Logs !!!
I used below commands too but I guess they clear "Elastic" cache:

$ curl -XPOST 'http://localhost:9200/_cache/clear'
$ curl -XDELETE 'http://localhost:9200/_all'

Thank you.

You're talking about Elasticsearch here, not Logstash. Logstash has no cache that would account for what you are seeing.

See them where?

I see them via "tcpdump" in my Linux box.
