This interface consists solely of procedures and variables that provide statistics on the historical state and behavior of the Compute Server "server". This is an 'on server' interface, not an RPC interface.

Event Notification
ServerEventType: TYPE = {startService, doneService};
ServerEvent: TYPE = RECORD [
type: ServerEventType, -- type of event
command: Rope.ROPE, -- command name started
startTime: BasicTime.GMT, -- command start time
endTime: BasicTime.GMT, -- command end time (meaningful for done events only)
remoteMachineName: Rope.ROPE, -- name of user's machine
chain: REF ServerEvent -- used internally to chain events together
];
NextServerEvent: PROC [REF READONLY ServerEvent ← NIL]
RETURNS [REF READONLY ServerEvent];
Server events are the start or finish of a request. NextServerEvent returns the next event that occurs after the event passed as an argument. An argument of NIL returns the next event that occurs after the call. NextServerEvent will WAIT if another event has not occurred yet.
END.
