  • RESTful

Logstash

  • Streaming ETL engine
  • Provides centralized data collection, processing and enrichment on the fly
  • Data agnostic
  • Wide range of integrations and processors
  • Ready-to-use monitoring and administrative panes built in Kibana

Kibana

  • Kibana is an open source data visualization dashboard
  • It provides visualization capabilities on top of the content indexed on an Elasticsearch cluster.
  • Kibana is simple and pretty intuitive to begin with. Despite such simplicity, it is highly customizable, allowing complex and detailed representations.
