VMS Help MONITOR, MONITOR, Command Qualifier Descriptions, /NODE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /NODE=(nodename,...)

    Specifies the nodes (up to 48 in a cluster) for which data is
    to be collected. If you specify more than one name, separate the
    names with commas, and enclose the list in parentheses.

    Remote monitoring in an OpenVMS Cluster environment might not be
    compatible for nodes that are running different OpenVMS versions.
    The following table shows the compatibility of versions for
    remote monitoring.

                       OpenVMS Alpha and  OpenVMS Alpha Version 1.5
                       VAX Version 6.n    and VAX Version 5.n

    OpenVMS Alpha and  Yes                No
    VAX Version 6.n

    OpenVMS Alpha      No                 Yes
    Version 1.5 and
    VAX Version 5.n

    To obtain data from an incompatible remote node, record the data
    on the remote node and then use the MONITOR playback feature to
    examine the data on the local node. The OpenVMS System Manager's
    Manual describes remote monitoring.
