The Reliability Monitor for Windows Vista gives system stability and details about events that impact reliability. It displays systems stability history and allows you see details on a every day basis about events that change reliability.

It computes Stability Index shown in System Stability Chart over lifetime of system. Reliability Monitor utilizes data given by RACAgent scheduled task. Reliability Monitor will begin showing a Stability Index rating and particular event information 24 hours after system installation.

To open Reliability Monitor in Microsoft Management Console, right tick Computer, and click Manage. In navigation pane, enlarge Reliability and Performance, enlarge Monitoring Tools, and tick Reliability Monitor. Membership in local Administrators group, or equal, is minimum necessary to utilize Reliability Monitor.

Depending on data together over lifetime of system, each date in System steadiness Chart contains a graph point displaying that day's System steadiness Index rating. The System Stability Index is a number from 1 to 10.

• New failures are slanted heavily than previous failures, permitting a development over time to be reflected in an ascending System Stability Index after reliability problem has been solved.

• Days when system is off or in a sleep state are not utilized when computing System Stability Index.

• If there is not sufficient data to compute a stable System Stability Index. When sufficient data has been recorded to make a steady System Stability Index, graphed line will be solid.

• If there are any important changes to system time, an Information icon will show on graph for every day on which system time was changed.

Reliability Monitor keeps up to a year of history for system steadiness and dependability events. System Stability Chart shows a rolling graph arranged by date. The above half of System Stability Chart shows a graph of Stability Index. In below half of chart, five rows track Reliability Events that either add to stability measurement for t system or give linked information about software installation and removal.

The Reliability Events recorded in System Stability Report contain following:

• System Clock Changes

• Software Installs and Uninstalls

• Application Failures

• Hardware Failures

• Windows Failures

• Miscellaneous Failures

Also to recognizing problems with individual applications and hardware parts, Reliability Monitor's graph allows you see whether major changes in stability started at similar time. As you can see all activity on a single date, you create informed decisions about how to solve.
