"The components for log parsing are different per logging tool. Fluentd uses standard built-in parsers (JSON, regex, csv etc.) and Logstash uses plugins for this. This makes Fluentd favorable over Logstash, because it does not need extra plugins installed, making the architecture more complex and more prone to errors"
