SISCO’s GOOSE Monitor is an essential troubleshooting tool for substation automation and protection systems that use IEC 61850 GOOSE messaging. The GOOSE Monitor provides an intuitive visualization of the state of the GOOSE messaging to identify where problems are occurring, and it enables the substation engineer to focus on those problems directly.

IEC 61850 GOOSE is a high-speed multicast messaging system that is used widely for protection coordination in and between substations. Operational substations using GOOSE can have thousands of messages per second being exchanged between hundreds of devices. Trying to determine if the protection messaging is working properly using traditional network monitoring tools or network packet sniffers is very difficult.

The GOOSE Monitor captures the publication and subscription status for all the GOOSE messaging and shows it in a real-time display that gives the substation engineer the ability to see at a glance if there are any problems and where the source of that problem might be.


  • Easy and flexible configuration automatically configures visualization and communications in a single step
  • Subscription visualization information is derived from the Substation Configuration Language (SCL) files and displayed as arrows/edges between nodes (devices) in the diagram
  • Hovering over nodes and edges in the diagram displays the IED and control block names respectively
  • Detailed GOOSE data can be viewed including data set values, subscription states, quality and timestamps
  • Runs on Server 2016 and Windows 10 as a 64-bit application
  • GOOSE/R-GOOSE traffic monitoring performed via connection to Ethernet trunk port on a network switch
  • Multiple Ethernet adapters supported
  • “Focus” Mode allows the engineer to isolate messaging related to a specific device to provide a simplified view of to assist in troubleshooting of large complex substations
  • Runs on standard computing platforms
