How to install

pfSense

Enable remote logging in the pfSense web UI by going to:

Status -> System Logs -> Settings

In Remote Logging Options, check "Enable Remote Logging", and add your remote Logstash server to the "Remote log servers". For example:

192.168.1.100:5140

Finally, check the "Everything" checkbox for "Remote Syslog Contents".

Logstash

Edit conf.d/10-syslog.conf and change the host conditional on line 4 to be your pfSense IP address if it is not the default 192.168.1.1.

Copy the contents of the conf.d and patterns directories to /etc/logstash/.

Kibana

Import the visualizations.json and dashboard.json.
