Microsoft® Windows Vista® includes Windows Reliability and Performance Monitor, which is a Microsoft Management Console (MMC) snap-in that combines the functionality of previous stand-alone tools including Performance Logs and Alerts, Server Performance Advisor, and System Monitor.
It provides a graphical interface for customizing Data Collector Sets and Event Trace Sessions.
The reliability of a system is the measure of how often the system operates as it is configured and expected to perform.
I downloaded and installed the upgrade from W7 to W8 on 25th Oct.
All appears well except for the Reliability Monitor.
The Reliability Monitor snap-in for Microsoft Management Console (MMC) provides a system stability overview and details about events that impact reliability.
It calculates the Stability Index shown in the System Stability Chart over the lifetime of the system.
Overall system performance might be limited by the access speed of the physical hard disks, the amount of memory available to all running processes, the top speed of the processor, or the maximum throughput of the network interfaces.
After identifying hardware performance limitations, IT professionals can monitor individual applications and processes to assess how much of the available resources they use.
In the other computer the graph does not work at all, it never shows anything.
Whenever I start or reboot that computer, it shows the message that the reliability monitor will take several hours to calculate the index and be updated for this first install of windows seven.
IT professionals can use a comprehensive analysis of performance of both application impact and overall capacity to help plan for deployment and grow system capacity with increasing demands.
