Description

Total number of direct sample hits attributed to the given object.

Number of sample hits taken when a thread was waiting (divided into blocked and spinning) on a thread level blocking primitive (mutex, read/write lock, or condition variable) or process level blocking primitive (semaphore, message queue, socket, pipe, file descriptor).

Number of direct sample hits taken when a thread was waiting on a thread level blocking primitive (mutex, read/write lock, or condition variable) or process level blocking primitive (semaphore, message queue, socket, pipe, file descriptor).

Column	Description
% Total Hits Waiting	Percentage of total sample hits waiting (blocked or spinning) on a thread level blocking primitive
	(mutex, read/write lock, or condition variable) or process level blocking primitive (semaphore,
	message queue, socket, pipe, file descriptor).
Sample Hits Waiting	Sample hits taken when a thread was waiting (blocked or spinning) on a thread level blocking
	primitive (mutex, read/write lock, or condition variable) or process level blocking primitive
	(semaphore, message queue, socket, pipe, file descriptor).
Blocking Primitive	The name of the Blocking Primitive represented as <type>@{addressname}. The type can
	be thread level blocking primitive mutexcond-varrwlockor inter process blocking primitive
	sem_id (semaphore id) msgq_id (message queue id) sock_fd (socket descriptor)
	regular_fd (regular file descriptor) char_dev_fd (character device file descriptor)
	blk_dev_fd (block device file descriptor) pipe_fd (pipe descriptor) reg_sock_fd
	(regular socket descriptor) stream_sock_fd (stream socket descriptor)
	multi_file_desc (multiple descriptor numbers for select, poll), <name> is a symbol associated
	with the primitive, and <address> is the primitive's address (shown when the address cannot
	be resolved to a symbol.
Sample Hits for	Sample hits attributed to a thread that was holding a primitive (for example, a mutex) when
Holder	other threads were waiting on the same primitive.
--For Waiter	Sample hits taken on a waiting thread that is blocked on the primitive held by the Holder thread
(HP-UX only)	(Marked by kernel thread ID and hot call path index.)
Callpath Index	Holder thread and waiter threads are identified by an index into Hot Call Path section.
Holder
--Waiter
(HP-UX only)
Holder's Kernel	Holder thread's kernel thread suffixed with the the name of the routine that the thread will execute
Thread ID	once it is created.

Description

Percentage of total sample hits directly in the call path. This represents the percentage of the total real time attributable to the call path.

Percentage of run hits directly in the call path. This represents the percentage of the total real time attributable to the call path that was in a run state.

Percentage of blocked hits directly in the call path. This represents the percentage of the total real time attributable to the call path that was in a blocked state.

Percentage of total sample hits directly in the call path. This represents the percentage of the total real time attributable to the call path.
