Filebeat - Non-zero metrics in the last 30s

Apparently logs are transferred from Filebeat to logstash, however the filebeat logs continiously show this message:

We have check the logs in the kafka there is no log on it. Can you please help to fix this issue.


The message you see is not an error message and it logs Filebeat's internal statistics. Since logs are being shipped to Logstash then Filebeat is properly configured.
