Abstract

Methods and apparatus, including computer program products, are provided for sizing an application running on a virtual machine. In one aspect, there is provided a computer-implemented method. The method may include registering, at a monitor, one or more controllers associated with one or more corresponding applications. Configuration information may be received for one or more corresponding applications. Event information may be provided to the one or more controllers to enable the one or more controllers to adjust one or more aspects of the corresponding applications. The event information may represent changes in resources (e.g., at the physical machine hosting the virtual machine and application). The aspects may be adjusted based on the changes. Related apparatus, systems, methods, and articles are also described.

Claims

registering, at a monitor, one or more controllers associated with one or more corresponding applications;

receiving configuration information for the one or more corresponding applications, the configuration information including a reconfigurable aspect of the one or more corresponding applications and an indication of circumstances for reconfiguration of the one or more corresponding applications;

generating, at the monitor, event information indicating at least a first change in an amount of at least one physical resource, a second change in a quantity of central processing units, a third change in a quantity of cache, a fourth change in a quantity of connections, and a fifth change in a quantity of files capable of being stored locally at a physical machine; and

providing the event information to the one or more controllers to cause the one or more controllers to adjust at least the reconfigurable aspect of the one or more corresponding applications, the change in the amount of the at least one physical resource mapped to a corresponding change in the reconfigurable aspect.

2. The computer-implemented method of claim 1 further comprising:

implementing the monitor as a resource monitor.

receiving changes to the resources of the physical machine.

9. The computer-implemented method of claim 1 further comprising:

accessing a virtual machine to obtain change information representative of the resources of the physical machine.

10. The computer-implemented method of claim 3, wherein the operation mode controller activates a value in the reconfigurable aspect causing another change in one or more of a cache, pool, or maximum number of processes associated with the one or more corresponding applications.

11. A non-transitory computer-readable medium containing instructions to configure a processor to perform a method, the method comprising:

registering, at a monitor, one or more controllers associated with one or more corresponding applications;
