Utilization()

void XrdCmsFinderTRG::Utilization ( unsigned int  util, bool  alert = false  )

virtual

Report utilization of this server. This may be used in lieu of general performance metric reporting. For consistent results use only one method.

Parameters

util	A value from 0 to 100 representing utilization. Values greater than 100 are set to be 100.
alert	When true the utilization is forcibly report to the cluster managers. Otherwise, reporting is done only when it will significantly change server selection.

Reimplemented from XrdCmsClient.
