About the Confidence Metric
One important metric displayed in the Analysis tab is the Confidence metric. During the
analysis phase, performance data about each selected system is collected. This data is
used to find a host with resources that match the collected data to determine a
recommendation for each candidate.
The recommendation indicates how well suited, based on the collected data, a candidate
is to a particular virtual machine host system. Confidence refers to the reliability of the
recommendation and it is a function of the duration of the analysis. Recommendations
based on longer periods of analysis – and therefore more performance data – receive a
higher level of confidence.
