Fluentd
Fluentd is an open-source data collector for unified logging, designed to unify data collection and consumption for better use and understanding of data. It provides a flexible plugin system to connect various data sources and outputs, enabling real-time log aggregation and processing across distributed systems. It is often used in cloud-native environments to handle log data from applications, containers, and infrastructure.
Developers should learn Fluentd when building or managing distributed systems, microservices, or containerized applications that require centralized logging and monitoring. It is particularly useful in DevOps and cloud environments for collecting logs from sources like Docker, Kubernetes, and cloud services, and forwarding them to storage or analysis tools like Elasticsearch, Amazon S3, or Splunk. Its lightweight nature and plugin architecture make it ideal for handling high-volume log data efficiently.
