SL Corporation Announces Extreme Caching in RTView for Asynchronous, Real-Time, Multi-Dimensional Data

Press Releases, RTView, SL in the News

Corte Madera, CA – February 1, 2011 – SL Corporation, a leading provider of Application Performance Management and component-level monitoring solutions, today announced major enhancements to the data management and analytics features of its RTView platform. The most significant of these is a new “database read-through capability which seamlessly blends short-term in-memory data (used for rapid real-time alert generation) with long-term historical data contained in a database. Without making a single SQL query, RTView users are able to perform week-over-week or similar trend analyses, referencing the same data model used for fast proactive alert calculations and health-state visualization.

“SL’s decades of experience with large-scale process monitoring systems, particularly in financial services and e-commerce applications, has provided us with true insight into what it takes to deal with huge volumes of real-time data, said Tom Lubinski, founder and CEO of SL Corporation. “We have been able to combine high-performance caching of column-oriented, time-series data with in-memory OLAP-style functionality such as grouping by date and time indices, as well as shield users from the in-memory/database boundary. Equally important, our customers can now make efficient use of memory and database space at the same time, offering a system that is easy to use and flexible.

As a key component of the complete RTView platform, the cache mechanism provides a holding area for real-time multi-dimensional monitoring data that arrive asynchronously. These data are indexed and buffered to an in-memory history table which can be mapped to any common database for persistent storage. A variety of functions may be used to compact, aggregate or transform these data for visualization, trend analysis,alert processing, etc. Some key features added to RTView caches include:

  • Database Read-Through via Cache – the ability to seamlessly navigate through, visualize and process data across the in-memory/database boundary without having to know when to make a SQL query. Data are accessed b ytable specifics and time range; there is no need to know where the data resides. This feature puts tremendous power into the hands of analysts and display designers.
  • Efficient Indexed Cache Insertion and Extraction- asynchronous data going into and out of the cache are processed using a highly efficient multi-dimensional indexing algorithm designed to update only those objects affected by a new piece of data. This can significantly minimize use of machine resources and data traffic across a network in a client-server implementation.
  • Cache Templates – RTView caches may be parameterized using variables that control the name, data sources and other configuration properties, making it possible to create data model “templates that can be applied easily to multiple real-time sources. Parameterization variables have been a key feature of RTView for a long time, making displays,analytics and alert notifications highly reusable, and significantly enhancing the productivity of users.

Recent releases of RTView have included numerous other enhancements that provide new visualization and interaction features, increasing the sophistication of its heatmaps, trend charts, object grids, composite objects and many other components. Such features have been found to be especially useful in monitoring the health state of large-scale applications dependent on multiple diverse subsystems which generate large volumes of data.

SL Corporation offers a number of derivative products built on RTView that address the monitoring needs around specific subsystems such as TIBCO EMS and BusinessWorks, and Oracle Coherence.New releases of these products will take advantage of the recent enhancements to the RTView platform and caching system.
