Setting Up and Managing Nodes

From the Node Management page, you can define nodes, specify which services they should run, assign nodes to environments, view security tokens, remove nodes and start or stop services. You can also view system usage metrics for the node’s host and services.

The following section provides information about node management in both hosted and on-premise deployments.

To view a list of nodes, select Administration > Node Management. Use the Column Filter at the upper right to show or hide columns in the list.

For hosted deployments:

FieldDescription
Node NameThe name given to the node when it was installed.
Node TypeThe selected node type - either Connector or Gateway Server.
IPThe IP address of the node when it was last connected to the Management Server.
State

The current activity state of the node.

  • Active --The node is assigned to an environment and has the latest configuration.
  • Outdated -- The node is assigned to an environment, but the configuration it is using does not reflect the latest values in the Management Server. You can update the node from the Management Console. See Upgrading the Node Server from the Management Console.
  • Inactive -- The node is not assigned to any environment.
Health

The condition of the node and its services. For example:

  • OK -- All services are running.
  • Starting -- One or more services is starting.
  • Stopped -- One or more services has stopped.
  • Disconnected -- The agent is disconnected from the Management Server.
  • Never seen -- The node has never connected to the Management Server. You can keep the node if it will be used in the future or delete it if it is no longer needed.

The value shown reflects the lowest health state of any service for that node. For example, if two services are running but one is stopped, the health status is shown as Stopped.

EnvironmentThe environment to which the node is assigned. Every node needs to be associated with an environment.
ServicesThe services enabled on this node. Hover over any service name to see the status of each service on the node.
AnyApp Connectors UsedThe names of the connectors with applications on the node.
Node VersionThe current version of the node.
Installed OnThe date on which the node was last installed.
Modified OnThe date on which the node information was last modified.
CPUThe CPU usage for the node, by percentage.
MemoryThe memory usage for the node, by percentage.
ActionsThe actions that can be performed on a node. See Stopping or Restarting Services.

For on-premise deployments:

The Node Management page lists each node that has been defined, showing the following information:

FieldDescription
Node NameThe name given to the node when it was installed.
IPThe IP address of the node when it was last connected to the Management Server.
State

The current activity state of the node.

  • Active --The node is assigned to an environment and has the latest configuration.
  • Outdated -- The node is assigned to an environment, but the configuration it is using does not reflect the latest values in the Management Server. You can update the node from the Management Console. See Upgrading the Node Server from the Management Console.
  • Inactive -- The node is not assigned to any environment.
