Logstash is an open source tool for collecting, parsing, and storing logs for future use. Kibana is a web interface that can be used to search and view the logs that Logstash has indexed. Both of these tools are based on Elasticsearch, which is used for storing logs. It is possible to use Logstash to gather logs of all types, but we will limit the scope to gather syslog. Our ELK stack setup has four main components: Logstash: The server component of Logstash that processes incoming logs Elasticsearch: Stores all of the logs Kibana: Web interface for searching and visualizing logs, which will be prox...
