Hi,

This is what my conf file looks like

![52%20pm](https://us1.discourse-cdn.com/elastic/original/3X/c/2/c2f1973137fdd280739bdd3b085b2a0a1e882f06.png)

The data is flowing and is visible when I debug the output. But it is not creating an index.

Command used to debug: usr/share/logstash/bin/logstash -f etc/logstash/conf.d/logstash.conf --log.level=info --config.debug

Index names can't contain uppercase characters. If you look in your Logstash log I'd expect it to contain many errors messages about this.
