I'm using Filebeat and Metricbeat version 8.9 on Redhat. Metricbeat has no any problem that can send a log to Kafka and shown on OpenSearch to be a dashboard. But Filebeat has no any error in the log that can connect and establish connection to Kafka but no logs were shown on OpenSearch.
How to investigate or debug this issue?
Additional question, I configure "logging.to_syslog" to be "false" but has a lot of message from Filebeat in /var/log/message file.
