Fields

The following table lists the data fields that provide information about each node. Each field has two names:

  • Field name - displayed in the output of the node list command
  • Short name - used to specify the columns displayed using the columns parameter

The short name is also used when specifying rows with a filter, for example when specifying nodes on which to perform an action with the node services command.
