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!

2021-06-20T23:20:32.182+0800	DEBUG	[publisher]	memqueue/ackloop.go:160	ackloop: receive ack [104875: 0, 382]

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