item

    Indicates the type of information to be reported about the local
    node (or about another node in your OpenVMS Cluster, if your
    system is part of an OpenVMS Cluster). Specify the item as a
    character string expression. Here are the items you can specify
    to get information about either your local node or another node
    in your OpenVMS Cluster system. If you do not specify the node
    argument, the information is returned for the local node.

    You can also specify any of the system parameters listed in the
    VSI OpenVMS System Management Utilities Reference Manual.

 node-name

    Specifies the node in your OpenVMS Cluster system for which
    information is to be returned. Specify the node as a character
    string expression. You cannot use the asterisk (*)  and the
    percent sign (%)  wildcard characters to specify the node-name
    argument.

 cluster-id

    Specifies the cluster node identification number for which the
    information is to be returned.

    To get information for all the nodes in a cluster, use the F$CSID
    lexical function to obtain each cluster system identification
    number, and use the cluster-id argument of F$GETSYI to gather
    information about each node.
