Welcome to Filebeat 8.10.3
Filebeat sends log files to Logstash or directly to Elasticsearch.
Getting Started
To get started with Filebeat, you need to set up Elasticsearch on
your localhost first. After that, start Filebeat with:
./filebeat -c filebeat.yml -e
This will start Filebeat and send the data to your Elasticsearch
instance. To load the dashboards for Filebeat into Kibana, run:
./filebeat setup -e
