Abstract: Systems, methods, and computer-readable media are provided for, among other things, generating web server performance metrics from log file information and storing the metrics offline in a centralized database. A collector accesses log file information from a log file for a web server and generates web server performance metrics on a per web page basis. The web server metrics include a number of requests for a web page, error count for the web page, average response time for the web page, total number of bytes transferred for the web page, and a number of times a service level objection for the web page was exceeded. The web server metrics are stored in a centralized database such that the metrics are available for offline web server performance reporting and analysis.

Abstract: A method of modeling and analyzing load across servers in a cloud computing environment. The method comprises analyzing a processor, a memory, and an input/output utilization of each of a plurality of servers, where each server is comprised of at least one logical partition. A chart displaying a usage pattern is presented for each server. A list of logical partitions is presented for each server of the plurality of servers. A selection of at least one logical partition on a first server of the plurality of servers and a selection of a second server of the plurality of servers is received. The utilization impacts of moving the logical partition to the selected second server are modeled and an updated chart displaying the usage pattern for each server based on the modeled migration of the logical partition is presented. The modeled optimal location stored in a disaster recovery plan.

Abstract: A method for looking up routing information for a person or program assigned to respond to an incident messages is explained herein. The method includes recognizing a routing code that was appended to either the object name or description. The routing code is recognized by a program that looks up the responders contact information in a table that correlates routing codes with designated responder information.

Abstract: One or more computer-readable media that enable a method of recording object configurations at and after an incident occurs in the object. The present invention captures object configurations surrounding an incident that allows changes to be made in response to the incident to be analyzed. The present invention also may generate an incident classification based on a comparison of the configuration when the incident occurs and after it is resolved.

Abstract: Systems and methods for collecting metrics from monitored systems are provided. Collected metrics may be further used for modeling system performance. Collected metrics may be analyzed to identify correlations between metrics, which may then be a basis for system modeling. One or more alarm thresholds may be set based upon system models. If the monitoring of a system indicates that an alarm threshold has been passed, the appropriate alarm may be issued. Alarm levels may vary for different alarm thresholds.

Abstract: The present invention provides a method of collecting system performance metrics from a plurality of monitored systems and reporting system performance metrics to a requesting client system. In accordance with the present invention, the system performance metrics are collected to a database so that requesting client systems requiring the metrics need not have access to each monitored system. The monitored systems may limit user access and maintain system security while still providing the metrics required to address system availability and load problems.

Abstract: The present invention provides a method for modeling the performance of a system comprising computer software operating on computer hardware. In accordance with the present invention, system performance is modeled by fitting non-linear curves to data points for system performance parameters, such as response time and throughput, as a function of load. Data points may be measured in testing may be measured through monitoring a system operating in a production environment. While a variety of non-linear curves may be used in accordance with the present invention, a logarithmic curve may be used to model system throughput and an exponential curve may be used to model system response time. By defining a relationship between throughput and response time a distance may be calculated between the curves, and this distance may be used to determine an optimal load.

Abstract: An improved network interface unit having a substantially smaller width than many prior art network interface units. The network interface unit comprises a single, planar circuit board assembly interconnected between incoming and outgoing telephone lines and incoming and outgoing customer premises lines. Two relays and a controller are mounted on the board. The controller monitors the transmission of data along the lines and, by activating the relays, provides communication and maintenance functions, such as loopback. The network interface unit utilizes a controller made up of (1) a processor-based software control system and (2) an integrally cooperating application specific integrated circuit. The controller may, for example, provide and monitor framing, detect and monitor signals, and convert bipolar data to unipolar data.

Abstract: An improved airspeed transducer for rotorcraft is disclosed having a pitot tube connected with a differential capacitive pressure sensor. The pressure differential from the pitot tube is a function of the airspeed squared. A diaphragm in the capacitive pressure sensor deflects when the dynamic pressure exceeds the static pressure from the pitot tube. This diaphragm deflection is sensed by electronics which provides an electrostatic attractive force between the diaphragm and a fixed plate such that the diaphragm is brought back to an undeflected, "at rest" position. The electrostatic force between the diaphragm and fixed plate is a function of the square of the voltage applied to the plate that creates this electrostatic force. Since the pressure differential from the pitot tube varies with the airspeed squared, the relationship between airspeed and feedback voltage is linear. Thus, the feedback voltage is a direct indication of sensed airspeed.

Abstract: A variable frequency vibration absorber adapted to be fixedly mounted in a fixed vibration prone system to coact with the system principal vibration excitation source to control system vibration. The vibration absorber is bifilar in construction and the natural frequency thereof is varied in proportion to the frequency of the vibration being generated by the principal system excitation source.
