What are the differences between Logstash and Fluentd for logging?

Logstash and Fluentd are both popular tools for logging, but they have some key differences. Logstash is part of the Elastic Stack and is designed for data collection and transformation, while Fluentd is more lightweight and focuses on data routing and aggregation.

Which one is easier to set up and use?

Fluentd is generally considered easier to set up due to its simpler configuration and lightweight nature. Logstash can be more complex, especially when integrating with the Elastic Stack.

Can they be used together?

Yes, they can be used together. For example, you can use Fluentd to collect logs and then send them to Logstash for further processing before indexing them in Elasticsearch.

What are the performance differences between them?

Fluentd is often praised for its lower resource consumption, making it suitable for high-throughput environments. Logstash, while powerful, can be more resource-intensive, especially with complex pipelines.
