3.3.3.2 Function Table

The following listing defines the plug-in implementation method function table:

Each method corresponds to a monitoring type. “_ec_perf_mon_app” is for call path monitoring, “_ec_perf_mon_svc” is for service monitoring, “_ec_perf_mon_sys” is for system server monitoring and “_ec_perf_mon_tran” is for transaction monitoring. Each method will be invoked at the corresponding monitoring type’s monitoring points. The method arguments are:

• struct perf_mon_1_Vtbl *ip:the virtual table pointer e.

  Note:

  Not required for custom plug-ins.
• FBFR32 **buf:the address of the metrics buffer in FML32 type.
• MONITORCTL *mon_ctl: the control structure.
• TM32U flags: the bit flag in a 32-byte, unsigned integer.
