8 WHAT? Details of Diagnostic Tools Lochlann O Donnell ESG Expert Engineer 22 November

9 MAIN TOOLS Apache JMeter Both the Client and the Finastra support can use JMeter, but the majority expected is from Finastra Support. This is generally used for load performance (that is, API) or Online SQL issues (Example: Circle close). Java VisualVM Both the Client and the Finastra support can use VisualVM, but the majority expected is from Finastra Support. This is a useful tool used for reporting performance issues such as memory usage. Java Mission Control (JMC) Both the Client and the Finastra support can use JMC. Use Flight Recorder to report relevant issues around delayed response, performance and it is good for snapshots during issue re-creation. Do you need a license? Loan IQ Dynamic Tracer Btrace will be used by Finastra Support and the scripts will be supplied during analysis of issues, if needed, as alternative to the debug jars. This tool is used to add debug code to help identify bugs. The Scripts are compiled into bytecode and submitted to the Loan IQ runtime.

10 DYNAMIC TRACE & ATTACH API The Attach API is an extension that provides a mechanism to attach to a Java virtual machine. A tool written in the Java Language, uses this API to attach to a target virtual machine and load its tool agent into that virtual machine. Our scripts are referred to as DynamicTrace scripts.

12 DYNAMIC TRACE COMMAND LINE Our preferred method for DataFix program data analysis. DataFix attempts to diagnose categorised data corruptions such as Object states being incorrect. See our published doc: Loan IQ DiagnosticTools_Overview_Guide.pdf Let s look at a sample config.
