I'm currently using the default setting for filebeat, and also sends the monitoring data to an Elasticsearch cluster.
My workflow for logs is Filebeat -> Logstash -> Elasticsearch
Just wondering how can we monitor the internal queue of Filebeat? From my understanding when Filebeat doesn't receive ack from Logstash it will queue up the data.
But how to tell if the queue is full and how to get alerts from it?
The monitoring dashboard on Kibana doesn't seem to reflect the relevant data.
