What is Fluentd+Kibana?
Fluentd+Kibana is a powerful combination of two popular open-source tools used for monitoring and logging infrastructure automation. Fluentd is a data collector that helps to unify data collection and consumption, while Kibana is a visualization tool that provides real-time insights into data. Together, they form a robust solution for monitoring and logging workflows, enabling users to collect, process, and visualize data in a scalable and efficient manner.
Key Features of Fluentd+Kibana
Immutable Storage Strategy
One of the key features of Fluentd+Kibana is its immutable storage strategy. This means that once data is written to the storage, it cannot be modified or deleted. This approach ensures data integrity and provides a tamper-proof record of all events. The immutable storage strategy is particularly useful for compliance and auditing purposes.
Incremental, Retention, and Replication
Fluentd+Kibana provides incremental, retention, and replication features that enable users to manage data efficiently. Incremental data processing allows for faster data processing and reduces storage requirements. Retention policies ensure that data is stored for a specified period, and replication provides high availability and disaster recovery capabilities.
