They are largely self-explanatory. 69# 70# samples 71# 72# 'samples' is the main table. It represents what instruction was executing at a point in time 73# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'. 74# 75# calls 76# 77# 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'. 78# 'calls' is only created when the 'calls' option to this script is specified. 79# 80# call_paths 81# 82# 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'. 83# 'calls_paths' is only created when the 'calls' option to this script is specified. 84# 85# branch_types 86# 87# 'branch_types' provides descriptions for each type of branch. 88# 89# comm_threads 90# 91# 'comm_threads' shows how 'comms' relates to 'threads'. 92# 93# comms 94# 95# 'comms' contains a record for each 'comm' - the name given to the executable that is running. 96# 97# dsos 98# 99# 'dsos' contains a record for each executable file or library. 100# 101# machines 102# 103# 'machines' can be used to distinguish virtual machines if virtualization is supported. 104# 105# selected_events 106# 107# 'selected_events' contains a record for each kind of event that has been sampled. 108# 109# symbols 110# 111# 'symbols' contains a record for each symbol. Only symbols that have samples are present. 112# 113# threads 114# 115# 'threads' contains a record for each thread. 116# 117# Views: 118# 119# Most of the tables have views for more friendly display. The views are: 120# 121# calls_view 122# call_paths_view 123# comm_threads_view 124# dsos_view 125# machines_view 126# samples_view 127# symbols_view 128# threads_view 129# 130# More examples of browsing the database with psql: 131# Note that some of the examples are not the most optimal SQL query. 132# Note that call information is only available if the script's 'calls' option has been used. 133# 134# Top 10 function calls (not aggregated by symbol): 135# 136# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10; 137# 138# Top 10 function calls (aggregated by symbol): 139# 140# SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol, 141# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count 142# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10; 143# 144# Note that the branch count gives a rough estimation of cpu usage, so functions 145# that took a long time but have a relatively low branch count must have spent time 146# waiting. 147# 148# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'): 149# 150# SELECT * FROM symbols_view WHERE name LIKE '%alloc%'; 151# 152# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187): 153# 154# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10; 155# 156# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254): 157# 158# SELECT * FROM calls_view WHERE parent_call_path_id = 254; 159# 160# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670) 161# 162# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%'; 163# 164# Show transactions: 165# 166# SELECT * FROM samples_view WHERE event = 'transactions'; 167# 168# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false. 169# Transaction aborts have branch_type_name 'transaction abort' 170# 171# Show transaction aborts: 172# 173# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort'; 174# 175# To print a call stack requires walking the call_paths table.
