these two icons. Notice here that I have four critical events. It looks like I have a problem with a device driver that for some reason keeps on stopping. Now I don't know exactly what this problem is. Notice that for each of these events, there's a link that says check for a solution. If I click it, then Reliability Monitor's going to access the Microsoft Knowledge Base and see if it can find a solution for the particular problem that we're having. Informational events are just nice to know items. For example, it tells us thatWindows update successfully updated each of these different services or products installed on the system. And if we need to, we can come over here and click on View technical details. Summary 13:02-13:13 That's it for this demonstration. In this demo, we looked at several tools that you can use to monitor system performance. First we looked at Task Manager, then we looked at Resource Monitor, then we looked at Performance Monitor, and then we ended this demonstration by looking at Reliability Monitor. A bottleneck occurs when a component is unable to keep up with demand and subsequently slows down other processes or functions. When a system seems to respond slowly, it's important to be able to accurately identify the component(s) that are causing the problem so you can take the proper actions to improve performance. Common components to examine in order to improve performance are: Processor (CPU) Hard disk Memory Network One way to identify components that are causing a bottleneck is to monitor system performance statistics. These statistics give you a measure of the activity of a certain aspect of the system. By recognizing abnormal statistics, you can identify the component that is overloaded or not responding appropriately. Windows identifies system performance statistics using the following terms: A counter is a specific statistic you can monitor (such as the amount of free memory or the number of bytes sent on a network card). An object is a statistic group, often corresponding to a specific type of hardware device or software process (such as the processor or memory). Use Task Manager, System Monitor, Resource Monitor, and Performance Monitor to track statistics. You should be familiar with the meaning and use of the following counters: Counter Description % Processor Time (processor utilization) Processor utilization is the amount (percentage) of time the processor spends doing non-idle tasks. Processor utilization should be relatively low, up to 40% on average. Processor utilization will spike (85 - 90% or higher) when a major task is launched or a significant task is performed. Utilization is reported for each processor in a multi-processor or multi-core system. A CPU that supports Hyper-Threading will show two utilization graphs for each processor.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
