Initially, the stack comprised of Elasticsearch, Logstash, and Kibana (ELK); however, Beats was added later:
- Elasticsearch: A search & analytics engine allows fast and scalable full-text searching, real-time analytics, and data visualization. Based on Apache Lucene, it functions as a NoSQL database.
- Logstash: An Elasticsearch index is created by gathering, parsing, and transforming logs from multiple sources as part of a data processing and transportation pipeline.
- Kibana: An intuitive dashboard for visualizing data that makes it easier to explore, analyze, and create reports using indexed data that is permanently saved in Elasticsearch.
- Beats: Local data gatherers who supply Elasticsearch or Logstash with data from several sources.
What is Splunk?
A commercial platform for security, log management, and analysis is called Splunk. It offers business analytics, security analysis, compliance monitoring, real-time monitoring, indexing, searching, and centralized log collection.
Through its Splunk Enterprise Security module, the platform enables machine learning, alerting, advanced analytics, data visualization, and security analytics.
Large amounts of machine-generated data are managed by Splunk through the use of proprietary Search Processing (SPL). It establishes connections with many data sources, safely indexes and saves the data, and offers users robust search and analysis tools.
The three important components of Splunk are:
- Forwarder: Data is ingested by the forwarder and then sent to the indexer.
- Indexer: Stores & indexes data and responds to search requests.
- Search head: The interface that allows these parts to be divided up among several servers or combined.
