At an application level with Vityl Capacity Management
In this guide, John Miecielica of Metavante, provides a step-by-step example showing how he uses Vityl Capacity Management to analyze IT resource consumption at an application level. This key capability is especially important in today’s environments where multiple applications run on a server or multiple servers might be required to...
In this paper we present an introductory analysis of throughput scalability for update intensive workloads (such as measured by the TPC-C or TPC-W benchmarks) and how that scaling is limited by serialization effects in the software-hardware combination that comprises any platform.
In this online article Dr. Gunther digs down into the UNIX kernel to find out how load averages (the “LA Triplets”) are calculated and how appropriate they are as capacity planning metrics.
This is the final online article concerning the concept of application scalability. Here, you will learn how to determine value of the parameters that control scalability.
TeamQuest (now Vityl Capacity Management) provides unintrusive mechanisms for instrumenting
applications and analyzing application performance. Neil Gunther describes how to use
those mechanisms.
