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

1. A computer-implemented method comprising:

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; and

providing event information 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 representative of one or more changes in resources, the one or more aspects adjusted based on the one or more changes.

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

implementing the monitor as a resource monitor.

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

implementing at least one of the controllers as an operation mode controller coupled to the resource monitor.

4. The computer-implemented method of claim 1, wherein registering further comprises:

registering, at the monitor, by providing a location of one of the controllers.

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

receiving the event information as a message representative of an increase in a quantity of central processing units.

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

receiving, at an operation mode controller, configuration information representative of an increase in a quantity of processes.

7. The computer-implemented method of claim 6 further comprising:

adjusting, by the monitor, the quantity of processes at an application.

8. The computer-implemented method of claim 1, wherein providing further comprises:

receiving changes to the resources of a 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 1, wherein providing further comprises:

using as the event information one or more of the following;

a change in a quantity of central processing units;

a change in a quantity of cache;

a change in a quantity of connections; and

a change in a quantity of files capable of being stored locally at a physical machine.

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

configuring, by one of the controllers, one of the applications, the configuration based on configuration information associated with the application being configured.

12. The computer-implemented method of claim 11, wherein configuring further comprises:

sizing one or more of the following aspects of the application;

a quantity of processes;

a quantity of cache used by the application;

a quantity of connections used by the application; and

a quantity of files stored by the application.

13. A 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;

receiving configuration information for the one or more corresponding applications; and

providing event information 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 representative of one or more changes in resources, the one or more aspects adjusted based on the one or more changes.

14. The computer-readable medium of claim 13 further comprising:

implementing the monitor as a resource monitor.

15. The computer-readable medium of claim 14 further comprising:

implementing at least one of the controllers as an operation mode controller coupled to the resource monitor.

16. The computer-readable medium of claim 13, wherein registering further comprises:

registering, at the monitor, by providing a location of one of the controllers.

17. A system comprising:

a processor; and

a memory, wherein the processor and the memory are configured to perform a method comprising;

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; and

providing event information 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 representative of one or more changes in resources, the one or more aspects adjusted based on the one or more changes.

18. The system of claim 17 further comprising:

implementing the monitor as a resource monitor.

19. The system of claim 18 further comprising:

implementing at least one of the controllers as an operation mode controller coupled to the resource monitor.
