ELK stack, what is that?

In a previous post I did a comparison of ELK and Splunk. I will take a few minutes here to kind of explain what ELK is. ELK stack (Elasticsearch, Logstash, Kibana) is simply amazing. Each program making up ELK brings their own uniqueness and are vital parts to making the thing work. Elasticsearch provides the search capability for Kibana. Logstash is the receiver of all the logs being ingested into ELK. Kibana is the visual portion of the stack allowing for the searching, correlation, and dashboards. The picture below brings it all together for us.
