Fluentd is an open source data collector for a unified logging layer. It is used to collect data from various sources and unify them into a single stream of data. It is designed to be a reliable and flexible tool for collecting and routing log data from multiple sources to multiple destinations. With its plugin-based architecture, Fluentd can easily be integrated with many other data sources and destinations, such as databases, message queues, and log management services. Fluentd supports a wide range of formats to collect and route data, and can be used for log aggregation and analysis, system monitoring, and data warehousing. It is also highly scalable, allowing for both on-premises and cloud deployments.
