Resolving the problem

There are a couple of known issues which can prevent the collection of statistics from early 6.x SVC cluster code.

It is recommended to upgrade to at least code.

IC76264 Incomplete data from onboard statistics collection.

IC75166 Large numbers of GUI connections can lead to host I/O performance degradation.
