DynaTrace update enhances continuous integration

September 30, 2009 —  A new version of dynaTrace Software's dynaTrace application performance management product is focused on enabling continuous integration through increased automation.

dynaTrace 3.1, released today, is the product of a strategic decision to make dynaTrace as automated as possible, said technology strategist Andreas Grabner. The objective is to make dynaTrace better suited for inclusion in continuous integration and test management environments.

The dynaTrace server provides external control through RESTful Web services and SOAP, Grabner said. The services can be used to extract data from reports that dynaTrace automatically generates, and pull that data into platforms such as Microsoft's Visual Studio Team Foundation Server.

"[Developers] can automatically pull information out of dynaTrace and visualize the problems between build one and build two," Grabner explained. "It extends the power of the unit test, regression analysis and complex architecture validations."

Incident workflows have also been automated. The dynaTrace server can now send out alerts to the person who needs to look at it, and the dynaTrace client will open to the incident when they log in, said Eric Senunas, senior director of marketing and communications at dynaTrace Software.

dynaTrace is designed to run and collect data continuously. Version 3.1 can process 75% more measurements per second, and there is a 100% improvement in analyzing memory dumps, as well as a 30% reduction in the size of its repository, the company says.

Part of that performance increase is due to simplified sensor configuration. Wizards help developers "focus on what makes sense," and they make recommendations about what should be instrumented or not, said Senunas.

Visibility was another focus area of the release. dynaTrace 3.1 helps organizations understand what causes performance problems in virtualized environments by determining whether those problems were caused by an application or a virtual machine, Grabner said.

The dynaTrace server provides accurate timing for the VMware platform by implementing VMware's performance counters technology. Prior to this release, instrumentation was not possible because VMware virtual machines would have given inaccurate performance metrics, Grabner explained. "Virtual machines are scheduled to go off and on by the hypervisor…It could not catch up with the interrupts."

The release also supports tracing applications that decouple services with an enterprise service bus (ESB); out-of-the-box support is provided for Oracle's ESB. Other ESBs can be configured, but developers will have to do more work, Grabner noted.

Lastly, there is a new SDK for creating monitors that trace transactions of custom protocols in Java and .NET. "It adds transaction support across tiers that we don't support yet," Grabner said.
