The hypertrend is on the same machine as pot and switch, right? You need to log them to database first and then display them on hypertrend. In object explorer, right click on the pot or switch, select edit datamember configuration. Select datamember, such as the default one "implicit", check "Log to historical database". Then, the value of the pot or swtich will be logged, and displayed on hypertrend.
