ELK is the acronym for three open source projects: Elasticsearch, Logstash, and Kibana. Elasticsearch is a search and analytics engine. Logstash is a server‑side data processing pipeline that ingests data from multiple sources simultaneously, transforms it, and then sends it to a “stash” like Elasticsearch. Kibana lets users visualize data with charts and graphs in Elasticsearch.
After the setup has completed, a pipeline will be created for Logstash and Filebeat. To view the dashboard visit the Kibana web page.
For using Elasticsearch data:
On the menu on the left side corner, select Discover to view the incoming hits and query a specific subset within a selected timeframe.
For examples on how to query in Kibana please visit the Elastico website here .
