They are largely self-explanatory. 67# 68# samples 69# 70# 'samples' is the main table. It represents what instruction was executing at a point in time 71# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'. 72# 73# calls 74# 75# 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'. 76# 'calls' is only created when the 'calls' option to this script is specified. 77# 78# call_paths 79# 80# 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'. 81# 'calls_paths' is only created when the 'calls' option to this script is specified. 82# 83# branch_types 84# 85# 'branch_types' provides descriptions for each type of branch. 86# 87# comm_threads 88# 89# 'comm_threads' shows how 'comms' relates to 'threads'. 90# 91# comms 92# 93# 'comms' contains a record for each 'comm' - the name given to the executable that is running. 94# 95# dsos 96# 97# 'dsos' contains a record for each executable file or library. 98# 99# machines 100# 101# 'machines' can be used to distinguish virtual machines if virtualization is supported. 102# 103# selected_events 104# 105# 'selected_events' contains a record for each kind of event that has been sampled. 106# 107# symbols 108# 109# 'symbols' contains a record for each symbol. Only symbols that have samples are present. 110# 111# threads 112# 113# 'threads' contains a record for each thread. 114# 115# Views: 116# 117# Most of the tables have views for more friendly display. The views are: 118# 119# calls_view 120# call_paths_view 121# comm_threads_view 122# dsos_view 123# machines_view 124# samples_view 125# symbols_view 126# threads_view 127# 128# More examples of browsing the database with psql: 129# Note that some of the examples are not the most optimal SQL query. 130# Note that call information is only available if the script's 'calls' option has been used. 131# 132# Top 10 function calls (not aggregated by symbol): 133# 134# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10; 135# 136# Top 10 function calls (aggregated by symbol): 137# 138# SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol, 139# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count 140# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10; 141# 142# Note that the branch count gives a rough estimation of cpu usage, so functions 143# that took a long time but have a relatively low branch count must have spent time 144# waiting. 145# 146# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'): 147# 148# SELECT * FROM symbols_view WHERE name LIKE '%alloc%'; 149# 150# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187): 151# 152# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10; 153# 154# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254): 155# 156# SELECT * FROM calls_view WHERE parent_call_path_id = 254; 157# 158# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670) 159# 160# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%'; 161# 162# Show transactions: 163# 164# SELECT * FROM samples_view WHERE event = 'transactions'; 165# 166# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false. 167# Transaction aborts have branch_type_name 'transaction abort' 168# 169# Show transaction aborts: 170# 171# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort'; 172# 173# To print a call stack requires walking the call_paths table.
