System Activities That are Monitored

While your computer is running, counters in the operating system are incremented to track various system activities.

The following system activities are tracked:

  • Central processing unit (CPU) utilization
  • Buffer usage
  • Disk and tape input/output (I/O) activity
  • Terminal device activity
  • System call activity
  • Context switching
  • File access
  • Queue activity
  • Kernel tables
  • Interprocess communication
  • Paging
  • Free memory and swap space
  • Kernel memory allocation (KMA)

The Oracle Solaris software provides several tools to help you track how your system is performing.
