For software installations and removals, an Information icon indicates a successful event of that type occurred, or a red warning icon indicates a failure of that type occurred. By looking to the right you can see on what type of row the error or information is logged. When one or more Reliability Events of each type are detected, an icon appears in the column for that date. These events either contribute to the stability measurement for the system, or provide related information about software installation and removal. In the lower half of the chart, there are five separate collapsible rows that track Reliability Events. It displays a graph of the Stability Index. On the top half of the Reliability Monitor window you can see the System Stability Chart. In the navigation pane, expand Reliability and Performance, expand Monitoring Tools, and click Reliability Monitor.You can also open it as a stand-alone snap-in in a new MMC window: Click Performance Information and Tools and then click the Advanced Tools link on the left. You might want to open Reliability Monitor from the Control Panel. Note: If you did not disable UAC (read my “ Disable User Account Control in Windows Vista” article) then you will be prompted to consent to the action you’re about to perform. Open Computer Management by right-clicking the Computer icon on the start menu (or on the Desktop if you have it enabled) and select Manage.
The System Stability Chart displays a rolling graph organized by date. It calculates the Stability Index shown in the System Stability Chart over the lifetime of the system. The Reliability Monitor is a snap-in for Microsoft Management Console (MMC) that provides a system stability overview and details about events that impact reliability. Inside the Performance tool you will find a Monitoring Tools folder, and in it you will find the Reliability Monitor. You can open the Performance snap-in from the Computer Management tool (see below), or as a separate snap-in.
One of them is the new and re-designed Performance Monitor.
