A method and system for predicting a user activity level associated with an application. An activity level is a number of transactions performed by users utilizing the application per time period or a number of users utilizing the application per time period. Measurements of activity levels are assigned to a user activity metric (UAM) variable, and associated values are assigned to a set of factors. At least one correlation coefficient between each factor and the UAM is calculated. In response to a maximum correlation coefficient associated with a factor being less than a pre-defined threshold, the factor is excluded from the set of factors to facilitate forming a subset of factors associated with correlation coefficients whose absolute values are greater than or equal to the pre-defined threshold. A regression model utilizing the subset is generated to predict an activity level.

A method and system for optimally scheduling a web conference managed by a web application. Date and time ranges are initialized with predefined values. A tentative start date included in the date range and a tentative start time included in the time range are automatically calculated, and are included in a tentative schedule for the web conference. A time period is determined by the tentative schedule and a duration of the web conference. The automatic calculation prevents the time period from overlapping a time interval during which processors utilized by the web application are to experience a peak load. The tentative schedule is presented to the user via the interface, and is recalculated and redisplayed in response to the user updating a load-related parameter. The user selects a final schedule, which is the tentative schedule or a user-specified schedule different from the tentative schedule.

A method and system for adapting an Information Technology (IT) structure to maintain service levels. An IT structure is deployed in an IT delivery environment. A service level associated with the IT structure is specified. At least one operational characteristic of the IT structure corresponding to the specified service level is identified. For each identified operational characteristic, a corresponding threshold is established in such that if the corresponding threshold is violated then the specified service level is not sustained. After establishing the thresholds, operation of the IT structure is monitored. The monitoring detects a condition wherein a measured value of a first operational characteristic has violated the corresponding threshold associated with the first operational characteristic such that the specified service level is not sustained by the measured value of the first operational characteristic, causing degradation of the specified service level.

A firewall rule generation method, a load balancing rule generation method, and a wrapper generation method, for an Information Technology (IT) system, associated computer program products, and an associated processes for integrating computing infrastructure. The firewall rule generation method generates firewall rules allowing data transmission between a computer and a client, and subsequently assigns the firewall rules to firewalls of the IT system. The load balancing rule generation method assigns a load balancing mechanism to a load balanced group to which execution of an application is assigned, wherein the load balanced group has servers therein. For a client and computer having a communication protocol therebetween that is not allowed by a security policy, the wrapper generation method generates a communication protocol wrapper that opens a Transmission Control Protocol (TCP) connection between the client and the computer such that the TCP connection is allowed by the security policy.

A method and system for estimating a screen refresh rate of a computing unit participating in an Internet-based collaboration. The computing unit receives a test image that includes pixels located at predefined positions and blinking at predefined frequencies. Measurements of the number of blinks of the pixels in a specified time period are collected. An average of the measurements summed over the predefined frequencies is calculated. A screen refresh rate is estimated by comparing the calculated average to a sum of multiple sums of simulated blinks of pixels in the specified time period. The average is closer to the sum than any of the other sums and the sum is associated with the estimated screen refresh rate.

An Information Technology (IT) system display method and computer program product. A description is provided of a configuration of devices, network segments, and vertical connectors relating to an IT structure. The devices are initially distributed to form a distribution of the devices in a matrix representing a display screen. A defined goal value of the configuration is a function of a length and weight of each network segment, a length and weight of each vertical connector, and a penalty for each crossing of a device by a network segment. An overlay pattern of the network segments and the vertical connectors overlayed on the matrix is displayed in accordance with the description and the final distribution of the devices in the matrix. The goal value for the final distribution is lower than for the initial distribution. The final distribution is displayed on the display screen together with the overlay pattern.

A system and method for facilitating identification of an attacking computer in a network is provided. A user attempting to login to a network application may be presented with a screen prior to the login which lists preconditions of gaining access to the application. If a user concurs with the preconditions, a security module is downloaded to the user's computer and executed which gathers various configuration settings and transmits the gathered information to a predetermined destination. The security module may also attempt to place a call to a predetermined destination over a modem in the computer to cause registration of caller-ID data when answered at the predetermined destination. Once the security check is completed, login may proceed with the network application. Any data gathered by the security module may be stored for later recall and use to identify the computer in the event of an attack.
