OC Systems Announces Response Time Instrumentation (RTI) for Internet Explorer

RTI measures actual end user response time at the browser; Integrates with IBM Tivoli Composite Application Manager

FAIRFAX, Va., March 2 /PRNewswire/ -- OC Systems, Inc. today announced the beta release of Response Time Instrumentation (RTI) for Internet Explorer, a new product that measures end-user response times for transactions initiated within Microsoft Internet Explorer. With RTI, performance engineers can obtain accurate information about the end-user experience, which can be used to more effectively triage and resolve application performance problems.

"Many companies say they offer tools or services that measure the end-user experience, but they are making estimates or using approximations such as synthetic transactions," said Oliver Cole, president of OC Systems, Inc. "These estimates do not necessarily reflect what end users are seeing. RTI measures the true end-user experience for actions that begin in Internet Explorer. This allows organizations to track the most important measurement- performance as the end user actually experiences it."

RTI for Internet Explorer is the first in a family of response-time measurement products that OC Systems is developing based on its work helping clients improve the performance of complex systems.

RTI uses an established and open industry standard, Application Response Measurement (ARM) version 4.0, to measure response times. ARM is a simple application programming interface that applications and middleware use to pass information about transactions to management software. An application calls ARM just before a transaction starts and again just after it ends. An ARM agent receives the calls, measures the transaction, and provides that data to a management system. The ARM standard has been adopted by organizations such as IBM, Hewlett Packard, SAS and Siebel.

Out of the box, RTI integrates with IBM Tivoli(R) Composite Application Manager (ITCAM) to provide immediate transaction tracing and decomposition from Internet Explorer through the back-end servers supporting the request. RTI can also integrate with any ARM agent or other management system that uses the ARM standard. RTI comes with its own ARM agent to do standalone monitoring, if a network-aware ARM agent is not available.

RTI is based on RootCause, OC Systems' robust and patented software instrumentation tool, and takes advantage of its ability to instrument applications in a lightweight and non-intrusive manner.

RTI is currently in beta. Interested parties should contact OC Systems at [email protected].
