Debug logs explanation

Hi, Can someone help me understand what does the below logs mean? I enabled the debug log in my filebeat to check if logstash is acknowledging the messages in a timely manner and if filebeat proceeds only when logstash acknowledged the messages/batch sent? Thank you!

This line identifies the number of events sent to the logstash output. Based on this, it appears filebeat is sending events to logstash successfully.
