Intelligently determining a virtual machine configuration during runtime based on garbage collection characteristics

Abstract:

Techniques for determining a virtual machine configuration based on garbage collection characteristics are disclosed. GC characteristics associated with GC cycles executed on a memory allocated for execution of an application are obtained. A relationship between GC variables is determined based on the GC characteristics collected over a time period of interest. A target GC characteristic is input to the GC variable relationship to determine an expected GC characteristic. The target GC characteristic may be, for example, a target cumulative pause time per a time interval. A virtual machine configuration is determined based on the expected GC characteristic. The virtual machine configuration is applied to a virtual machine executing the application.
