Update

To update a probe you need to do the following:

• Download the zip of the new agent (in the configuration application on the main dashboard)
• Remove the nudge.x.y.z.jar file (x.y.z being the agent’s version ) and place it next to existing agent.
• Change the application startup configuration (parameter: - javaagent: …)
• The new agent will be used when the application’s server restarts

Advanced Instrumentation

Probe provides multiple ways to identify methods and classes for instrumentation:

• automatic :

fits most JEE standards: EJB, Servlet, RMI, JMS, Web services, …

• explicit through configuration :

using trace_classpath_regex configuration, suitable for Batch processing, non-JEE classes, or when source code is not available (3rd party library). Detailed information about that parameter can be found in the parameter list.

• explicit through annotation :

using @Trace annotation directly in the instrumented methods, only available in your application code (no 3rd party libraries). This third option allows to:

• fine-tune transaction and layer naming
• use dynamic data for naming (method parameters, return values, errors, …)
• add metadata to calls to allow further filtering and grouping in the Nudge portal.

For setup and usage, refer to the corresponding open source project.
