Blueflood is a multi-tenant distributed metric processing system created by engineers at Rackspace. It is used in production by the Rackspace Monitoring team to process metrics generated by their monitoring systems. Blueflood is capable of ingesting, rolling up and serving metrics at a massive scale.
Simply put, Blueflood is a big, fast database for your metrics.
Data from Blueflood can be used to construct dashboards, generate reports, graphs or for any other use involving time-series data. It focuses on near-realtime data, with data that is queryable mere milliseconds after ingestion.
Data is stored using Cassandra to make Blueflood fault-tolerant and highly-available. In contrast to forebearers such as CarbonDB or RRDTool, your Blueflood cluster can expand as your metrics needs grow. Simply add more Cassandra nodes.
Written in Java, Blueflood exists as a cluster of distributed services. The services are:
You send metrics to the ingestion service. You query your metrics from the Query service. And in the background, rollups are batch-processed offline so that queries for large time-periods are returned quickly.
Blueflood was created by the Rackspace Monitoring team at Rackspace to manage raw metrics generated from the Rackspace Monitoring system. Blueflood is now largely promoted by the Rackspace Metrics team which provides Blueflood-as-a-Service as a free service (yes, really – just talk to us). Since making the product open source, several other large companies have begun using the tool.
Blueflood is an open source under the Apache 2.0 license.
There are a couple different ways that you can get started with Blueflood:
Assuming git and docker installed:
git clone -b goru97/docker --single-branch https://github.com/rackerlabs/blueflood.git cd blueflood/contrib/blueflood-docker/ docker-compose up &
mkdir blueflood_demo; cd blueflood_demo vagrant init blueflood/blueflood; vagrant up
