Evenflow

Evenflow is a simple service for submitting sFlow datagrams to Graphite. It accepts sFlow datagrams from multiple network devices and proxies the data to a Carbon listener.

Currently only Generic Interface Counters are supported. All other message types are discarded.

Usage

Starting up evenflow is very straightforward. It recognizes a few ENV options such as CARBON_PREFIX, CARBON_URL, STATS_INTERVAL and VERBOSE. Setting STATS_INTERVAL=10 will cause evenflow to report internal statistics (evenflow.metrics) every 10 seconds (defaults to 60s). When VERBOSE=1 it will print out each line to stderr that it also sends to the Carbon socket.

$ CARBON_PREFIX=network CARBON_URL=carbon://localhost:2003 ruby evenflow.rb
