The Reliability and Performance Monitor is based on
stability statistics. It tracks changes to your server and unexpected errors, which are
translated into a stability index that you can use to gauge your server??™s overall reliability.
In short, the more stable your server, the more reliable it is.
As always, local administrators have access to perform any kind of performancegathering
function; however, two additional built-in groups can be used to grant nonadministrators
access to performance data. The Performance Log Users group should

contain user accounts that may schedule logging of performance counters, enable trace
providers, and collect event traces both locally and remotely. Performance Monitor Users
group members can also view performance counters locally or remotely. This group is
useful if you want to allow nonserver administrators such as application developers to
view server performance data remotely without granting them full administrative access
to your servers.
TIP If you run Reliability and Performance Monitor locally on the server you want to monitor, you
need to account for the extra processing and memory resources used by the tool when looking at your
overall data. In many cases, it may make more sense to record performance metrics remotely from a
different server or workstation so that it minimizes the possibility of skewing the gathered data.
