If you don't speak fluent Ethernet, it sometimes helps to get a graphical view of what your network is doing. Skydive offers visual insights that could reveal complex error patterns.

A picture is worth a thousand words, and sometimes, a visual image of your network can save you hours of troubleshooting. Skydive [1] is an open source network analyzer designed to provide a graphical representation of the IT components and how they interact. I'm not talking about wiring but about the data flows between the nodes. Skydive stores this information in a central location. You can interact with Skydive using a web interface, the command line, or an API.

Skydive consists of a central analyzer and many agents (Figure 1). The agents run on Linux hosts and report network configuration and statistics to the analyzer. The analyzer listens to feedback from its agents and stores the input in a database. Gradually, the analyzer gets to know the entire topology and traffic flows between endpoints. The admin can access the new Skydive instance via the analyzer's web interface.

Agents act as "dumb" data forwarders. The brain of the analyzer is a NoSQL database, either Elasticsearch or OrientDB. Skydive scales horizontally: If an analyzer is at capacity with its agents, additional analyzers can step in and serve additional agents. The analyzers fill the same database with flow information while keeping their configurations in sync using etcd.
