Abstract

A method for visualizing and simulating server consolidation of different virtual machines in a virtualized data center can include identifying different server computers in a virtualized data center, computing load metrics for each of the server computers, and rendering a graph of the computed load metrics for the server computers in a graphical user interface (GUI) in a host computer. The method further can include selecting a source one of the server computers and also a target one of the server computers and further selecting a virtual machine for prospective migration from the source one of the server computers to the target one of the server computers. Yet further, the method can include further computing prospective load metrics for the source and the target resulting from the prospective migration of the virtual machine to the target. Finally, the method can include displaying in the GUI respective graphs of the prospective load metrics for each of the source and the target.

Claims

identifying a plurality of server computers in a virtualized data center;

computing load metrics for each of the server computers;

rendering a graph of the computed load metrics for the server computers in a graphical user interface (GUI) in a host computer;

selecting as a source one of the server computers and also as a target one of the server computers and further selecting a virtual machine from the source one of the server computers for prospective migration to the target one of the server computers;

further computing prospective load metrics for the source one of the server computers and the target one of the server computers resulting from the prospective migration of the virtual machine to the target one of the server computers; and

,

displaying in the GUI respective graphs of the prospective load metrics for each of the source one of the server computers and the target one of the server computers.

2. The method of claim 1, wherein rendering a graph of the computed load metrics for the server computers in a graphical user interface (GUI) in a host computer, comprises rendering a scatterplot of the computed load metrics for the server computers in the GUI in the host computer.

3. The method of claim 2, wherein a first axis of the scatterplot represents a current state of the server computers and a second axis of the scatterplot represents a trend in changes of state of the server computers.

4. The method of claim 3 wherein the current state is current load experienced by the server computers and the trend in changes of state is a trend in changes in load experienced by the server computers.

5. The method of claim 4, wherein the trend in changes in load experienced by the server computers comprises a trend of CPU utilization for each of the server computers based upon observed changes in CPU utilization for each of the server computers.

6. The method of claim 1, wherein selecting a source one of the server computers and also a target one of the server computers and further selecting a virtual machine from the source one of the server computers for prospective migration to the target one of the server computers, comprises:

displaying both a pane for the source one of the server computers with load metrics for each virtual machine in the source one of the server computers and also a pane for the target one of the server computers with load metrics for each virtual machine in the target one of the server computers; and

,

dragging an icon for a virtual machine in the source one of the server computers from the pane for the source one of the server computers to the pane for the target one of the server computers.

7. A monitoring data processing system comprising:

a host computer with processor and memory;
