Usage

Prepare

Filebeat

Put the Filebeat config in your filebeat inputs directory -->/etc/filebeat/inputs.d/or add the content of the Filebeat config belowfilebeat.inputs:in your/etc/filebeat/filebeat.yml

If you prefere the first option, you need to create theinputs.ddirectory, and tell filebeat to use this:

#============================== Filebeat inputs ===============================

filebeat.config.inputs:
enabled:true
path:${path.config}/inputs.d/*.yml

Logstash

Put the Logstash config in the config directory/etc/logstash/conf.d,
and the grok patterns into the patterns directory/etc/logstash/patterns.d

Don't forget to restart Filebeat and Logstash after editing configs

Filebeat:fail2ban.yml
Logstash config:fail2ban.conf
Logstash pattern:fail2ban.grok

Grafana

Filebeat:grafana.yml
Logstash config:grafana.conf
Logstash pattern:grafana.grok

Rspamd

Logstash config:rspamd.conf

UFW (uncomplicated firewall) / IPTABLES

Logstash config:ufw.conf
Logstash pattern:ufw.grok
