yesterday I updated one of my servers from NW65SP5 to NW65SP6. What I
watched for a longer time, is that some values from the Health Monitor seem
not to be equal to the same values in the statistic trend graphs.

For example from SP5:
Health Monitor says that the Available Logical Space is currently 901 MB
while the statistic trend graph says the available logical space is
somewhere around 1400 MB (see the attached picture).

In SP6 this issue is vice versa.
Health Monitor says the Available Memory is 1340 MB while Statistic Trend
Graph says it's about 340 MB.

Which values will now show the true available values?

Thanks for your suggestions.
