Nerve Management System

The Nerve Management System is a web-based service that permits management of Nerve Blue nodes that are registered. It can be used to:

  • Monitor nodes
  • Deploy and control workloads on a node
  • Manage workloads

Note

Google Chrome or Firefox Version 63 or later are recommended for the usage of the Management System.

Tabs
  • Node Tree Tab
    This is the default view of the Management System. It displays all registered nodes in a node tree. Add, delete and move tree elements freely here. It mainly serves an organizational purpose and does not impact the functionality of the nodes. Nodes and workloads can be managed in the node details view, which is reached through the node tree.
  • Node List Tab
    Selecting the nodes tab displays a list of all available nodes that have been registered in the Management System. Add and remove nodes, as well as edit their details here.

    • Sub menus
    • Updates
      Available updates for nodes can be found here.
    • Update Log
      Past node updates can be viewed here. When an update is performed, this view also shows the current progress of the update.
Workloads (7) All workloads that have been provisioned in the Management System are listed here. Workloads can be added, deleted, disabled and edited through this menu. New versions of workloads can also be added here.
Deploy (8) Workloads that have been provisioned previously can be deployed using this menu. However, there are two sub menus available here:
  • Log
    Find a list of all workloads that have been deployed or are currently being deployed. Also, view details of all deployments and delete log entries from the list.
  • Dry Run
    A dry run is a simulation of a workload deployment. It allows to test out if the deployment of a workload could be successful. However, note that a successful dry run is not a guarantee for successful deployment.
Labels (9) This is a list of all labels that have been defined in the Management System. Add, delete, edit and merge labels here.
Users (10) This is the user management menu. It lists all registered users and allows to edit profiles and add new users.
