node
Manages nodes in the cluster
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 listcommand - Short name - used to specify the columns displayed using the
columnsparameter
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.
