Fluentd plugin

Fluentd is an open source data collector for unified logging layer. Fluentd tries to structure data as JSON as much as possible: this allows Fluentd to unify all facets of processing log data: collecting, filtering, buffering, and outputting logs across multiple sources and destinations (Unified Logging Layer). Fluentd supports memory- and file-based buffering to prevent inter-node data loss. Fluentd also support robust failover and can be set up for high availability.
