ELK Stack

Definition

The ELK Stack is a powerful collection of three open-source products: Elasticsearch, Logstash, and Kibana, used for searching, analyzing, and visualizing log data in real time. It helps in managing and monitoring data generated from continuous integration and continuous delivery processes by providing insights through log analysis and visualization tools. This combination enables teams to enhance their CI/CD pipelines by quickly identifying issues, improving performance, and ensuring reliability.

5 Must Know Facts For Your Next Test

1. The ELK Stack allows for real-time monitoring of applications and infrastructure, which is critical for identifying performance bottlenecks during CI/CD processes.
2. By aggregating logs from multiple sources, the ELK Stack helps teams maintain a single source of truth for debugging and performance monitoring.
3. Using Kibana, teams can create customizable dashboards to visualize key metrics related to deployments and application health.
4. Logstash supports multiple input sources, making it versatile for gathering logs from different environments in the CI/CD pipeline.
5. The ELK Stack is widely adopted in DevOps practices, facilitating faster feedback loops and improved collaboration among development and operations teams.

Review Questions
