Todo:: TODO(sligocki): Rename to statistics_logger().

Reimplemented from net_instaweb::Statistics.

void net_instaweb::SharedMemStatistics::GlobalCleanup ( MessageHandler * message_handler )

This should be called from the root process as it is about to exit, when no further children are expected to start.

static void net_instaweb::SharedMemStatistics::GlobalCleanup	(	AbstractSharedMem *	shm_runtime,
		const GoogleString &	segment_name,
		MessageHandler *	message_handler
	)

static

Like above, but can be done after object got cleaned up, by passing a saved SegmentName(). Precondition: init must have returned 'true'.

bool net_instaweb::SharedMemStatistics::Init	(	bool	parent,
		MessageHandler *	message_handler
	)

This method initializes or attaches to shared memory. You should call this exactly once in each process/thread, after all calls to AddVariables, AddHistograms and SetSuggestedNumBuckets (as well as any other histogram range configurations) have been done.

The root process (the one that starts all the other child threads and processes) must be the first one to make the call, with parent = true, with all other calling it with = false.

Returns true if successful.
