Glarn Network Management Tool
Glarn is a Python-based network management tool that gathers information from both HP IMC and the VAN SDN Controller, providing valuable data on OpenFlow devices and allowing operators to easily manage their SDN environment. With features like automatic system contact information gathering and the ability to list nodes and flows, Glarn simplifies network management tasks. It also allows operators to add, edit, delete, and list device information in its database. Explore Glarn for efficient network management in your SDN environment.

License Glarn is offered as freeware. There is no support for this application and it is being offered as is. Enhancement requests can be sent to chewie@wooieware.com
Whoami? When working with the HP VAN SDN controller, and others, the operator gets limited information about switches that are receiving openflow messages from the controller. In network management information about location, owner and vendor can be obtained by the snmp contact information. Glarn can determine if dpids being managed by the SDN controller are also being managed by HP IMC and will automatically gather the system contact information and populate the glarn database. For devices not found in IMC, glarn creates manageable database entires to allow for operators to add, edit, delete and list this information. Glarn will also allow for the listing of all nodes and flows in the SDN environment.

Glarn gathers information from both IMC and the VAN SDN Controller. Having a large number of OpenFlow devices under management with IMC can offer additional information to operators of the SDN Controller glarn db
