The _NTO_TRACE_SYSTEM class includes events related to the system as a whole.
| Event | traceprinter label | IDE label | Emitted when: |
|---|---|---|---|
| _NTO_TRACE_SYS_ADDRESS | ADDRESS | Address | A breakpoint is hit |
| _NTO_TRACE_SYS_APS_BNKR | APS_BANKRUPTCY | APS Bankruptcy | An adaptive partition exceeded its critical budget |
| _NTO_TRACE_SYS_APS_BUDGETS | APS_NEW_BUDGET | APS Budgets | SchedCtl() is called with a command of SCHED_APS_CREATE_PARTITION or SCHED_APS_MODIFY_PARTITION. Also emitted automatically when the adaptive partitioning scheduler clears a critical budget as part of handling a bankruptcy. |
| _NTO_TRACE_SYS_APS_NAME | APS_NAME | APS Name | SchedCtl() is called with a command of SCHED_APS_CREATE_PARTITION |
| _NTO_TRACE_SYS_FUNC_ENTER | FUNC_ENTER | Function Enter | A function that's instrumented for profiling is entered |
| _NTO_TRACE_SYS_FUNC_EXIT | FUNC_EXIT | Function Exit | A function that's instrumented for profiling is exited |
| _NTO_TRACE_SYS_IPI, _NTO_TRACE_SYS_IPI_64 | IPI | IPI | An interprocessor interrupt is received |
| _NTO_TRACE_SYS_MAPNAME, _NTO_TRACE_SYS_MAPNAME_64 | MAPNAME | Map Name | dlopen() is called. Note that the kernel generates only _NTO_TRACE_SYS_MAPNAME_64 events, even for 32-bit processes. |
| _NTO_TRACE_SYS_MMAP | MMAP | MMap | mmap() or mmap64() is called |
| _NTO_TRACE_SYS_MUNMAP | MUNMAP | MMUnmap | munmap() is called |
| _NTO_TRACE_SYS_PAGEWAIT | PAGEWAIT | Pagewait | A page fault is being handled |
| _NTO_TRACE_SYS_PATHMGR | PATHMGR_OPEN | Path Manager | An operation involving a path name—such as open()—that's routed via the libc connect function occurs. The connect function sends a message to procnto to resolve the path and find the set of resource managers that could potentially match the path. It's upon receiving this message that procnto emits this event. |
| _NTO_TRACE_SYS_POWER | POWER | Power | A CPU enters or exits idle mode |
| _NTO_TRACE_SYS_PROFILE, _NTO_TRACE_SYS_PROFILE_64 | PROFILE | Profile | Every clock tick, if statistical profiling is enabled |
| _NTO_TRACE_SYS_RUNSTATE | RUNSTATE | Runstate | The runstate for a CPU changes |
| _NTO_TRACE_SYS_SLOG | SLOG | System Log | A message is written to the system log |
| _NTO_TRACE_SYS_TIMER | TIMER | Timer | A timer expires |
