Cluster Monitoring software?

[Alex]

So why is SGI releasing the API but not the good stuff, i.e. the GUI? It
appears to be very nice product, but for users I don't see the point of
developing their own GUIs for it as only the first layer of the total
solution is open sourced. Does that mean that SGI might change the whole
concept with the next release if better free GUIs are available?
