self collector

  "self": {
    "read_mem_stats" : true,
    "read_goroutines" : true,
    "read_cgo_calls" : true,
    "read_rusage" : true
  }

The self collector reads the data from the runtime and syscall packages, so monitors the execution of the cc-metric-collector itself.

Metrics:

• If read_mem_stats == true:
  • total_alloc: The metric reports cumulative bytes allocated for heap objects.
  • heap_alloc: The metric reports bytes of allocated heap objects.
  • heap_sys: The metric reports bytes of heap memory obtained from the OS.
  • heap_idle: The metric reports bytes in idle (unused) spans.
  • heap_inuse: The metric reports bytes in in-use spans.
  • heap_released: The metric reports bytes of physical memory returned to the OS.
  • heap_objects: The metric reports the number of allocated heap objects.
• If read_goroutines == true:
  • num_goroutines: The metric reports the number of goroutines that currently exist.
• If read_cgo_calls == true:
  • num_cgo_calls: The metric reports the number of cgo calls made by the current process.
• If read_rusage == true:
  • rusage_user_time: The metric reports the amount of time that this process has been scheduled in user mode.
  • rusage_system_time: The metric reports the amount of time that this process has been scheduled in kernel mode.
  • rusage_vol_ctx_switch: The metric reports the amount of voluntary context switches.
  • rusage_invol_ctx_switch: The metric reports the amount of involuntary context switches.
  • rusage_signals: The metric reports the number of signals received.
  • rusage_major_pgfaults: The metric reports the number of major faults the process has made which have required loading a memory page from disk.
  • rusage_minor_pgfaults: The metric reports the number of minor faults the process has made which have not required loading a memory page from disk.
