Global resource attributes are cluster-wide resource attributes, such as available network bandwidth of a file server or the free disk space on a network-wide available file system.
Global resource attributes can also be associated with load reports if the corresponding load report contains the GLOBAL identifier, as described in Load Parameters. Global load values can be reported from any host in the cluster. No global load values are reported by default, therefore there are no default global resource attributes.
Concrete values for global resource attributes are determined by the following items:
Global load reports.
Explicit definition in the complex_values parameter of the global host configuration. See Configuring Hosts.
In association with a particular host or queue and an explicit definition in the corresponding complex_values lists.
Sometimes none of these cases apply. For example, a load value might not yet be reported. In such cases, the attribute does not exist.
