Probable anomalies associated with at least one data metric may be detected across a series of windows of time series data by comparison of data to a threshold. An estimated probability of anomalies for each of the windows of time series data may be determined based on the detected probable anomalies and the threshold. The windows of time series data may be ranked based on the estimated probabilities. Probable anomalies associated with highest ranked windows of time series data may be output to a user.

System and method for ranking anomalies

A system for integrating resource capacity planning and workload management, implemented as programming on a suitable computing device, includes a simulation module that receives data related to execution of the workloads, resource types, numbers, and capacities, and generates one or more possible resource configuration options; a modeling module that receives the resource configuration options and determines, based on one or more specified criteria, one or more projected resource allocations among the workloads; and a communications module that receives the projected resource allocations and presents the projected resource allocations for review by a user.

Computer resource utilization modeling for multiple workloads includes a computer obtaining resource utilization data, the resource utilization data having groups of computer resource utilization measurements made during time intervals for a plurality of workloads. The computer determines parameters representing a distribution of the computer resource utilization measurements for each of the groups to generate a baseline of distributions across the time intervals for each of the plurality of workloads. The computer sums the baselines of distributions for the plurality of workloads to generate a combined baseline of distributions across the time intervals for a combination of the plurality of workloads.

The present invention provides a method, a system, and computer readable media for reconciling a web-server session state with a client web-browser state. The method involves responding to an nrequest, by reading an msession-state identifier included in the request, where n&#x3e;m&#x2267;1. The server then assumes an msession state associated with the msession state identifier.

A computer-automated system analyzes payment options by acquiring usage information from a resource utilization measurement monitor executing in a system and accessing current financial information relating to a plurality of payment options from a financial database. Financial effect is evaluated for the plurality of payment options that result for the acquired usage information.

A management workstation has an interface for receiving notifications of data-center facilities infrastructure events. A manager determines emergency power settings for managed computing resources in response to the notifications. The settings are then communicated to the resources.

A temporally normalized processor utilization trace is generated.

Temporally normalized processor utilization

The present invention provides a system and method for generating models of a computer system. The method involves generating an original model of a computer system in an original configuration, and performing an original series of changes of the original model to yield an intermediate model. The original series of changes is recorded. The method further involves tracking the actual configuration of the computer system so as to detect a revised configuration of the computer system. Then, a resultant model is generated that corresponds to the computer system in a potential resultant system configuration that would result from a series of reconfigurations corresponding to said original series of changes or a revision thereof being applied to the system in its revised configuration rather than in its original configuration.

Computer system model generation with tracking of actual computer system configuration

A method of performing resource analysis on one or more cards of a computer system is described and disclosed. In an embodiment, the method includes identifying one or more affected hardware identifiers. Each affected hardware identifier corresponds to any of the cards. Configuration information of the computer system is gathered. Moreover, the configuration information is used to analyze the affected hardware identifiers to identify any affected resource of the computer system. The identification of any affected resource is independent of a system-wide hardware scan of the computer system. Furthermore, one of a plurality of severity levels is assigned to each identified affected resource based on predetermined criteria. The severity levels include a low severity level, a medium severity level, and a high severity level. Each severity level represents degree of impact to the computer system if functionality of the identified affected resource became unavailable.

The present invention is directed to a method and apparatus in which a UNIX operating system can be configured or tuned without rebooting the system. Advantageously, the present invention is directed to a dynamic mechanism for updating kernel parameters which is persistent and lasts across reboots. The present invention provides a dynamic kernel tunable framework for changing tunables in a kernel without rebooting. A graphical user interface displays and is used to change graphical values and settings of dynamic tunables.

Dynamic kernel tunables

A system that automatically detects logical errors when compiling a program. The system detects such logical errors as a signal handler routine modifying the errno global variable, a signal handler routine calling a non-reentrant library function, a signal handler routine calling a non-reentrant user function, and a signal handler routine calling a memory allocation function without first disabling all other signal handlers. The system also detects using '/n' at the end of a string.

Method for locating errors in a computer program

A system that automatically detects logical errors when compiling a program. The system detects such logical errors as calling a virtual function of a class passed into a function by value; virtual functions called from constructors or destructors; multiple definitions of classes, enums, or typedefs; multiple declarations of an object; mixing standard C I/O routines with C++ routines; a member function or data of a class hiding inherited member function or data; problems with the order of dynamic initialization; or failing to initialize non-static and non-class data members. The system also will suggest the use of the contact attribute for a member function that does not modify data members and suggest the use of const for parameters of functions when the parameter is not modified.

A system and method for identifying dynamic resource misuses via inspection that may result in problems like corrupted heap memory and memory leaks in a target program. The parameters and variable are marked with a particular state type. The target program is then analyzed one function at a time via symbolic execution so as to interpret each function based on the states of the variable and parameters and the operations performed by the basic blocks comprising the function. A state transition table is utilized to define the new state of a destination based on the operation and current state. Coding violations identified by the state transition table are reported and a signature of the function created for use when analyzing other functions that call the current function being analyzed.

System and method for checking for dynamic resource misuse in a computer

A computer-based system and method for obtaining specified resources of an object within a functional process in an object-oriented window server environment where the functional process contains this resource information, and for communicating these specified resources to an outside functional process. The outside functional process can use this information in a variety of ways, particularly for testing purposes.
