Charles Dunbar presented on using Puppet to set up centralized logging and metrics. Centralized logging makes logs easy to search across all servers, saves space by deleting local logs, and makes it harder for attackers to hide activity. The demonstration used Puppet to configure Rsyslog, Logstash, Elasticsearch, and Kibana on Vagrant VMs to collect, parse, store, and visualize logs in real time for improved visibility into patterns and trends.
