Abstract:
The monitoring technology capable of reducing total monitoring cost without degrading the monitoring capability in accordance with the configuration of the large-scale service system and quickly comprehending the state of the service system after the configuration change. A monitoring system in which information processing apparatuses constituting the service system are objects to be monitored has a monitoring manager program and a plurality of monitoring agent programs, and objects to be monitored having the same performance characteristics are sorted into the same groups. In each of the groups, parties where monitoring is carried out at a short monitoring interval and parties where the monitoring is carried out at a long monitoring interval are provided. The performance of objects to be monitored in the party of the long monitoring interval is estimated from the performance of the objects to be monitored in the party of the short monitoring interval.
Abstract:
A system, method and computer program product for event-based sampling to monitor computer system performance are provided. The system includes a sample buffer to store a sample of instrumentation data, where the instrumentation data enables measurement of computer system performance. The system also includes a sample segment selector to isolate a segment of the sample of instrumentation data as an event. The system further includes an instrumentation counter counting in response to a combination of the event and a sample pulse, and asserting a sample interrupt indicating that the sample of instrumentation data is ready to logout from the sample buffer.
Abstract:
Performance sensitivities to a change in performance capabilities of computational units of a computer system are determined based on measured utilization metrics for each of the computational units. In order to determine the performance sensitivities, in one approach, the computational units are operated at a first performance level, and respective first utilization metrics are determined. The computational units are then operated at a second performance level and respective second utilization metrics are determined. The sensitivity to performance capability change, e.g., a frequency change, is determined based on the respective first and second utilization metrics. The performance sensitivities of the computational units to a change in performance capability are continually updated in response to, e.g., a process context change of a computational unit or in response to a predetermined period of time elapsing since the last sensitivity to a performance capability change was determined for a computational unit.
Abstract:
Performance data is received at a Remote Performance Monitor (RPM) Server residing on a target virtual operating system within a virtual data center complex. The performance data is generated, and served at predefined intervals, by a Central Performance Data Server operable for the virtual operating system within the virtual data center complex. At least a portion of the performance data is saved in memory accessible to the RPM Server. Then, responsive to a request form an RPM Client residing on an originating virtual machine within the virtual data center complex, at least a portion of data residing in the memory is extracted by the RPM Server and served to the RPM Client.
Abstract:
A system for auditing the use of software on a computing device comprises a data collection server. In response to a communication link being available between the data collection server and the computing device, the data collection server is configured to: (1) receive from the computing device, via the communication link, data including (a) a software identifier identifying the software, (b) a device identifier identifying the computing device, and (c) an event identifier identifying a usage event performed by the software; (2) access a database storing previously received software identifiers, device identifiers, and event identifiers; and (3) update the database to include the received data. A method for auditing the use of software on a computing device is also disclosed.
Abstract:
In a three-tier ERP implementation, multiple servers are interconnected through one or more network infrastructure. Users may observe poor performance due to the complexity and the number of interconnected components in the implementation. Herein is devised a process for tuning the software component by applying tuning techniques to the OS, SAP application and Database Management System software. For each component, the process identifies potential tuning opportunities of various subcomponents. The process is iterated numerous times through all software components while applying the tuning techniques to derive the most optimal performance for the ERP implementation.
Abstract:
The present invention extends to methods, systems, and computer program products for distributed aggregation on an overlay network. Embodiments of the invention utilize tiers of nodes that are cascaded in a layered system. Each tier reduces the size of data by orders of magnitude through pre-aggregation. Thus, high volume streams of messages can be reduced to lower volume streams at large scales, such as, for example, the Internet. No central coordination is used; thus there is no central point of failure or bottleneck. When a node fails, other nodes in the same tier as the failing node automatically take over the responsibilities of the failed node.
Abstract:
Methods and systems are disclosed for measuring performance event rates at a computer and reporting the performance event rates using timelines. A particular method tracks, for a time period, the occurrences of a particular event at a computer. Event rates corresponding to different time segments within the time period are calculated, and the time segments are assigned colors based on their associated event rates. The event rates are used to display a colored timeline for the time period, including displaying a colored timeline portion for each time segment in its associated color.
Abstract:
A computer-implemented method for visualization of website analytics overlaid upon the source website is described. In one example embodiment, the method can comprise receiving website usage data associated with a customer website, aggregating the website usage data to generate website statistics, processing the website statistics to generate the website analytics, receiving credential data associated with a substantially current user of the customer website, based on the credential data, identifying the substantially current user as a customer associated with the customer website, and selectively communicating the website analytics to the customer website, the website analytics being displayed within a website analytics interface having one or more graphical reports over the website. The interactive graphical reports include reporting elements positioned over website elements corresponding to the reporting elements, which are independent of any variations in the size and shape of the display window or screen. In another example embodiment, the method can comprise pre-configuring and remotely storing display options, and selectively and automatically altering the display of the customer website pages, presenting different versions of those pages to different users based on the preconfigured and remotely stored display options to establish which versions of the page are more effective.
Abstract:
A data storage system manager includes one or more servers, at least one data collector deployed on at least one of the servers, at least one policy engine deployed on at least one of the servers, and at least one configuration manager deployed on at least one the servers. The at least one data collector is configured to collect resource utilization information including data storage wear rate of data storage system data storage modules. The at least one policy engine is configured to evaluate the collected information and to initiate changes to a configuration of the data storage system based on data storage wear rate and work load distribution policies. The at least one configuration manager is configured to implement the changes initiated by the at least one policy engine to control the data storage wear rate and a skew of the work load distribution within the data storage system.
