Monitoring an OpenFlow Network

For a complete picture of the network, we offer several tools that help monitor both the control plane and the data plane.

Control Plane

• Control event reconstruction: oftrace
• Passive NOX modules: eventlogger
• Active monitoring of switches: oflops

Data Plane

• Network Visualization: envi
• Data plane active monitoring: ofpeck

Report Generation

• Parsing monitoring logs: ofhammer
• Time-correlated data visualization: OpenSeer

Following figure illustrates where each of these tools fit into the deployment.
