Abstract: A method for setting configuration parameters (301) for at least one software system (300), comprises the steps of: a) receiving an identification of a set of configuration parameters (301) for at least one software system (300) to be optimized; b) selecting a random value from a predetermined range (305) for each configuration parameter (301) of interest; c) setting each configuration parameter (301) to a corresponding random value selected (305); d) running an application using the values selected (309); e) gathering performance information relating to the software system (300) while the application is running; f) repeating steps b) through e) for a selected number of times; and g) performing an analysis of the performance information gathered to determine optimal configuration parameters (301). The method can be performed by a programmable computer system (800) running program instructions for carrying out the above method steps or by a specialized apparatus such as an ASIC.

Abstract: The invention provides a solution for passively monitoring a computer system. In an embodiment, a virtual server 330 is accessed by an indexing agent 342 that is contained in an indexing appliance 340. The virtual server is located on a physical server 310 and is one of a plurality of virtual system instances on a common physical server. The indexing appliance is separate from the virtual server and, as such, the indexing agent is not executed within the virtual server, itself. The indexing agent retrieves a virtual image 332 of the virtual server which may include instructing a virtualization hypervisor (232) of the virtual server to perform a checkpoint operation or snapshot of the virtual image. The indexing agent indexes the virtual image to extract features 334 indicative of changes in the virtual server. These features are analyzed to perform passive monitoring of the virtual server. Since the indexing appliance is separate from the virtual server for which passive monitoring is being performed, the indexing agent can perform the retrieving and the indexing without utilizing agents executing within the virtual server.
