They are largely self-explanatory. 68# 69# samples 70# 71# 'samples' is the main table. It represents what instruction was executing at a point in time 72# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'. 73# 74# calls 75# 76# 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'. 77# 'calls' is only created when the 'calls' option to this script is specified. 78# 79# call_paths 80# 81# 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'. 82# 'calls_paths' is only created when the 'calls' option to this script is specified. 83# 84# branch_types 85# 86# 'branch_types' provides descriptions for each type of branch. 87# 88# comm_threads 89# 90# 'comm_threads' shows how 'comms' relates to 'threads'. 91# 92# comms 93# 94# 'comms' contains a record for each 'comm' - the name given to the executable that is running. 95# 96# dsos 97# 98# 'dsos' contains a record for each executable file or library. 99# 100# machines 101# 102# 'machines' can be used to distinguish virtual machines if virtualization is supported. 103# 104# selected_events 105# 106# 'selected_events' contains a record for each kind of event that has been sampled. 107# 108# symbols 109# 110# 'symbols' contains a record for each symbol. Only symbols that have samples are present. 111# 112# threads 113# 114# 'threads' contains a record for each thread. 115# 116# Views: 117# 118# Most of the tables have views for more friendly display. The views are: 119# 120# calls_view 121# call_paths_view 122# comm_threads_view 123# dsos_view 124# machines_view 125# samples_view 126# symbols_view 127# threads_view 128# 129# More examples of browsing the database with psql: 130# Note that some of the examples are not the most optimal SQL query. 131# Note that call information is only available if the script's 'calls' option has been used. 132# 133# Top 10 function calls (not aggregated by symbol): 134# 135# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10; 136# 137# Top 10 function calls (aggregated by symbol): 138# 139# SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol, 140# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count 141# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10; 142# 143# Note that the branch count gives a rough estimation of cpu usage, so functions 144# that took a long time but have a relatively low branch count must have spent time 145# waiting. 146# 147# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'): 148# 149# SELECT * FROM symbols_view WHERE name LIKE '%alloc%'; 150# 151# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187): 152# 153# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10; 154# 155# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254): 156# 157# SELECT * FROM calls_view WHERE parent_call_path_id = 254; 158# 159# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670) 160# 161# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%'; 162# 163# Show transactions: 164# 165# SELECT * FROM samples_view WHERE event = 'transactions'; 166# 167# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false. 168# Transaction aborts have branch_type_name 'transaction abort' 169# 170# Show transaction aborts: 171# 172# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort'; 173# 174# To print a call stack requires walking the call_paths table.
