Ns2 project in Iraq

         Ns2 project in Iraq note that the analysis phase of monitoring often requires the comparison of time fields among multiple events that may have occurred on ns2 project in Iraq different nodes of the distributed system. We have not explored any novel methods for event or time synchronization . For most of our applications, it has been ns2 project in Iraq sufficient to assume that processor clocks are synchronized to within tens of microseconds. In conclusion, views as defined above are useful for specifying dynamic monitoring for several reasons: The real-time attributes of program monitoring, such as maximum monitoring ns2 project in Iraq delays, etc., are easily specified.

         Performance specifications regarding monitoring are easily stated, which results in the generation of efficient collection and analysis using probes, extended sensors, and analysis code in resident and central monitors. In essence, the monitor ns2 project in Iraq can tailor its collection and analysis mechanisms to single applications or even single execution runs of applications. Language and system independence are achieved by ns2 project in Iraq expressing views in terms of attributes rather than in terms of program variables present ns2 project in Iraq in the application.

       In addition, any program described with the E-R model may be monitored, including operating system components and systems software for a ns2 project in Iraq more extensive discussion of language issues in the specification of monitoring. The attachment of graphical representations to monitoring views is the subject of other ns2 project in Iraq past and future research performed by our group. It should be apparent from the in the previous section that the attribute and view languages permit users to express application-dependent monitoring views in a high level, declarative fashion.
