Kibana is an open source browser based visualization tool mainly used to analyze large volume of logs in the form of line graph, bar graph, pie charts, heat maps, region maps, coordinate maps, gauge, goals, timelion etc. The visualization makes it easy to predict or to see the changes in trends of errors or other significant events of the input source. Kibana works in sync with Elasticsearch and Logstash which together forms the so called ELK stack.
