Ns2 project in Singapore
Ns2 project in Singapore asindicated in, all attribute specifications are compiled into probes and into attributes of entities stored in the database. This is also the case for the attributes ofrelationships that can be monitored. Probe implementations ns2 project in Singapore are linked and loaded with the target application’s processes and resident monitors, and they are registered with the central monitor. Similar actions are taken for the sensor ns2 project in Singapore implementations and the analysis code derived from the view specifications explained next. Attributes that can be monitored constitute the basis from ns2 project in Singapore which the set of actual events to be monitored is drawn.
That set is specified with the viewlanguageby programmers as a collection of monitoringviewsstated as entities, relationships, and sets ns2 project in Singapore in the database. The sample view below concerns the queue sizes of two QueueManagerobjects. The viewlanguagesyntax accepted by the ns2 project in Singapore prototype described later is similar to that ns2 project in Singapore appearing below. This view is defined to be activewhen the value of queue– Sizeis greater than 24 in both instantiations of QueueManager; this boolean expression on attributes is ns2 project in Singapore termed theACTIVEpredicate.
When a view is active, the value of itsderived attributes, mentioned in the targetlistof the viewin this case, the target list consists of the single attributethisqueuesizecomputed by the expression QueueManager. are computed and made ns2 project in Singapore available by the monitor to other environment tools, such as the adaptation controller and the graphical display. Since the monitoring system need not collect, record, and ns2 project in Singapore display information at times at which the view is not active , the ACTIVE predicate reduces the amount of work themonitor must do, thereby reducing monitoring perturbation.
