Win32_PerfRawData_PerfOS_Objects Class

The Object performance object consists of counters that monitor logical objects in the system, such as processes, threads, mutexes, and semaphores. This information can be used to detect the unnecessary consumption of computer resources. Each object requires memory to store basic information about the object.
Namespace value is root/CIMV2.
WMI Provider value is WmiPerfInst.


Properties

  • Caption
  • A short textual description (one-line string) for the statistic or metric.

  • Description
  • A textual description of the statistic or metric.

  • Events
  • Events is the number of events in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. An event is used when two or more threads try to synchronize execution.

  • Frequency_Object
  • Not applicable.

  • Frequency_PerfTime
  • Not applicable.

  • Frequency_Sys100NS
  • Not applicable.

  • Mutexes
  • Mutexes counts the number of mutexes in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. Mutexes are used by threads to assure only one thread is executing a particular section of code.

  • Name
  • The Name property defines the label by which the statistic or metric is known. When subclassed, the property can be overridden to be a Key property.

  • Processes
  • Processes is the number of processes in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. Each process represents the running of a program.

  • Sections
  • Sections is the number of sections in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. A section is a portion of virtual memory created by a process for storing data. A process can share sections with other processes.

  • Semaphores
  • Semaphores is the number of semaphores in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. Threads use semaphores to obtain exclusive access to data structures that they share with other threads.

  • Threads
  • Threads is the number of threads in the computer at the time of data collection. This is an instantaneous count, not an average over the time interval. A thread is the basic executable entity that can execute instructions in a processor.

  • Timestamp_Object
  • Not applicable.

  • Timestamp_PerfTime
  • Not applicable.

  • Timestamp_Sys100NS
  • Not applicable.
