 This Project aims to give you better insight of what's going on your pfSense Firewall. It's based on some heavylifting alrerady done by devopstales and opc40772. Since it still was a bit clumsy and outdated I wrapped some docker-compose glue around it, to make it a little bit easier to get up and running. It should work hasslefree with a current Linux that has docker and docker-compose. Thanks as well to MatthewJSalerno for some Streamlining of the Graylog provisioning Process.

+I have recently updated the whole stack to utilize Graylog 4 and Elasticsearch 7 and Grafana 7. I don't include any directions for Upgrading GL3/ES6 to GL4/ES7.
