C.5.8. Linux::Process Counts by State
The Linux::Process Counts by State probe identifies the number of processes in the following states:
• Blocked — One that has been switched to the waiting queue and the state of the process has been
switched to the waiting state.
• Defunct — One that has terminated (either because it has been killed by a signal or because it has
called exit()) and whose parent process has not yet received notification of its termination by
executing (some form of) the wait() system call.
• Stopped — One that has been stopped before its execution could be executed.
• Sleeping — One that is in the Interruptible sleep state that can later be reintroduced into memory
and execution will resume where it left off.
