Although I've been primarily focusing on issues related to monitoring openSUSE Servers, I thought I'd take a peek at how SLES is doing it.

For the most part I've found no technical documentation.
From the bits I've read, am I correct that the plumbing details are largely hidden, the general approach is to just install an agent on the system to be managed/monitored and things "just work?"

And, generally speaking any modifications are largely done through the GUI application?
