COLLECTING AND MOVING DATA AT SCALE
Sada Furuhashi Chief ArchitectInvented Fluentd, Messagepack
BACKGROUND
HIGH LEVEL ANALYTICS ARCHITECTURE
Collect Store Process Visualize
THE CHALLENGE
Collect Store Process Visualize
How do we shorten the collection process?
Easier & Shorter Time ExcelTableau
THE PROBLEM
TYPICAL ARCHITECTURE BEFORE FLUENTD
Log Server

THE FALSE SOLUTION
MULTIPLY CONNECTIONS / COMBINATION EXPLOSION

FLUENTD IN PRODUCTION
MICROSOFT
Operations Management Suite uses Fluentd: "The core of the agent uses an existing open source data aggregator called Fluentd. Fluentd has hundreds of existing plugins, which will make it really easy for you to add new data sources."

"At Atlassian, we've been impressed by Fluentd and have chosen to use it in Atlassian Cloud's logging and analytics pipeline."

The architecture of Fluentd (Sponsored by Treasure Data) is very similar to Apache Flume or Facebook’s Scribe. Fluentd is easier to install and maintain and has better documentation and support than Flume and Scribe.
