Refer to that script for details.## Tables:##	The tables largely correspond to perf tools' data structures.  They are largely self-explanatory.##	samples##		'samples' is the main table. It represents what instruction was executing at a point in time#		when something (a selected event) happened.  The memory address is the instruction pointer or 'ip'.##	calls##		'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.#		'calls' is only created when the 'calls' option to this script is specified.##	call_paths##		'call_paths' represents all the call stacks.  Each 'call' has an associated record in 'call_paths'.#		'calls_paths' is only created when the 'calls' option to this script is specified.##	branch_types##		'branch_types' provides descriptions for each type of branch.##	comm_threads##		'comm_threads' shows how 'comms' relates to 'threads'.##	comms##		'comms' contains a record for each 'comm' - the name given to the executable that is running.##	dsos##		'dsos' contains a record for each executable file or library.##	machines##		'machines' can be used to distinguish virtual machines if virtualization is supported.##	selected_events##		'selected_events' contains a record for each kind of event that has been sampled.##	symbols##		'symbols' contains a record for each symbol.  Only symbols that have samples are present.##	threads##		'threads' contains a record for each thread.## Views:##	Most of the tables have views for more friendly display.  The views are:##		calls_view#		call_paths_view#		comm_threads_view#		dsos_view#		machines_view#		samples_view#		symbols_view#		threads_view## More examples of browsing the database with psql:#   Note that some of the examples are not the most optimal SQL query.#   Note that call information is only available if the script's 'calls' option has been used.##	Top 10 function calls (not aggregated by symbol):##		SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;##	Top 10 function calls (aggregated by symbol):##		SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,#			SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count#			FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;##		Note that the branch count gives a rough estimation of cpu usage, so functions#		that took a long time but have a relatively low branch count must have spent time#		waiting.##	Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):##		SELECT * FROM symbols_view WHERE name LIKE '%alloc%';##	Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):##		SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;##	Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):##		SELECT * FROM calls_view WHERE parent_call_path_id = 254;##	Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)##		SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';##	Show transactions:##		SELECT * FROM samples_view WHERE event = 'transactions';##		Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.#		Transaction aborts have branch_type_name 'transaction abort'##	Show transaction aborts:##		SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';## To print a call stack requires walking the call_paths table.
