What is Splunk?
Splunk, unlike the ELK stack, is a proprietary log analysis and observability platform developed and managed by Splunk Inc. It offers ease of integration and a robust feature set but comes with a higher price tag. Splunk comprises three key components: forwarder, indexer, and search head, collectively facilitating data collection, indexing, and analysis.
- Forwarder: Splunk forwarders push data to a remote indexer, ensuring seamless data transfer and ingestion.
- Indexer: The indexer manages data indexing and search queries, breaking down log data into individual events, annotating them with metadata, and writing them to disk for efficient search and retrieval.
- Search Head: The search head serves as the front-end web interface, providing users with controls and user management functionalities.
