Select Appearance. Appearance allows you to change Colours, Fonts and Border. Click OK to close the properties box. Computers that have no new software installations or failures are considered stable and can achieve the maximum system stability index of The more installations and failures that occur on a computer, the lower the system stability index drops toward a minimum value of 0. Reliability Monitor is useful for diagnosing intermittent and long-term problems. For example, if you were to install an application that caused the operating system to fail once a week, it would be very difficult to correlate the failures with the application installation.
With Reliability Monitor, you can quickly browse both failures and the application installations over time. If recurring failures begin shortly after an application installation, the two might be related. The rows below the chart show icons for successful and unsuccessful software installations, application failures, hardware failures, Windows failures, and other miscellaneous failures. Then click the View menu and select Show Hidden Tasks.
Data Collector Sets gather system information, including configuration settings and performance data, and store it in a data file. You can later use the data file to examine detailed performance data in Performance Monitor or view a report that summarizes the information.
Active Directory Diagnostics Present only on domain controllers, this Data Collector Set logs kernel trace data, Active Directory trace data, performance counters, and Active Directory registry configuration. LAN Diagnostics Logs network performance counters, network configuration data, and important diagnostics tracing.
Use this Data Collector Set when troubleshooting complex network problems, such as network time-outs, poor network performance, or virtual private network VPN connectivity problems. System Performance Logs processor, disk, memory, and network performance counters and kernel tracing. Use this Data Collector Set when troubleshooting a slow computer or intermittent performance problems. Use this Data Collector Set when troubleshooting reliability problems such as problematic hardware, driver failures, or Stop errors also known as blue screens.
Key changes include:. Addresses an issue in the servicing stack when you install an update that has been signed by using only the SHA-2 hash algorithm. Microsoft strongly recommends you always install the latest servicing stack update SSU for your operating system before installing the latest monthly security update. Installing servicing stack updates SSU makes sure that you have a robust and reliable servicing stack so that your devices can receive and install Microsoft security fixes.
After you install a servicing stack update together with other updates, a restart may be required to complete the installation. During this restart, you may find yourself stuck at a particular stage and see a "Stage 2 of 2" or "Stage 3 of 3" message. This should occur only one time and does not prevent updates from installing successfully. Microsoft strongly recommends that you install the latest servicing stack update SSU for your operating system before you install the latest rollup.
SSUs improve the reliability of the update process to mitigate potential issues while you install the Rollup and while applying Microsoft security updates. This update is available through Windows Update. When you turn on automatic updating, this update will be downloaded and installed automatically.
To get the standalone package for this update, go to the Microsoft Update Catalog website. This update replaces the previously released update Learn about the terminology that Microsoft uses to describe software updates. For more information about SSUs, see Servicing stack updates. What is the result of a program allocating memory for use but not freeing up that memory when it is finished using it? They can track the activity of the software, document errors, and extract analytical information.
Component logs are intended for use in troubleshooting long-term problems and for software developers seeking debugging information. Why is it important to examine the resources utilized by specific applications and processes over time?
A bottleneck could occur from an increased server load, hardware failure, or changed server roles. To monitor basic memory performance, which counters should you use? In what ways does Windows Server enhance the auditing capabilities of previous Windows versions? When auditing Active Directory changes, the system can now log both the old and the new values so that you have a record of the previous values before changes were made. Windows Server also adds subcategories to the global categories.
Forwarded Events Which of the following logs is the primary Windows Server operational log? System Which type of event is triggered when there is service degradation or an occurrence that can potentially cause service degradation in the near future?
Warning By default, which of the following logs is visible in the Event Viewer console? Operational Which tool within the Reliability and Performance Monitor console displays hundreds of different statistics? Performance Monitor Which of the following is not an available view in Performance Monitor? MMC consoles Action menu In the Add Counters dialog box, which of the following is not a piece of information that you need to specify to add a counter to the display?
System Which type of event warns of a problem that is not likely to affect the performance of the component or process where the problem occurred, but could affect the performance of other components or processes on the system?
Error Which type of log contains events targeted at end-users or administrators that indicate a problem and offer a possible solution? Admin Which type of log contains events that signify a change in the application or service, such as the addition or removal of a printer? Operational By default, at what time interval does the Performance Monitor graph update counter values? True False False By default, all counters use the percentage as the unit of measurement.
