In the KS8 cluster, some parameters of the Dremio nodes are displayed abnormally, such as the CPU and memory of the master node, and the CPU information of the executing node.
Coordinator only does planning which should be quick, so it would be difficult to catch a time when there are concurrent queries are getting planned and takes long. For executor, only when queries are running does CPU go up. What does your host OS CPU metrics say?
I apologize for misunderstanding the meaning of this list. I thought it would list the total number of CPU cores and memory capacity.
