They are largely self-explanatory. 82# 83# samples 84# 85# 'samples' is the main table. It represents what instruction was executing at a point in time 86# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'. 87# 88# calls 89# 90# 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'. 91# 'calls' is only created when the 'calls' option to this script is specified. 92# 93# call_paths 94# 95# 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'. 96# 'calls_paths' is only created when the 'calls' option to this script is specified. 97# 98# branch_types 99# 100# 'branch_types' provides descriptions for each type of branch. 101# 102# comm_threads 103# 104# 'comm_threads' shows how 'comms' relates to 'threads'. 105# 106# comms 107# 108# 'comms' contains a record for each 'comm' - the name given to the executable that is running. 109# 110# dsos 111# 112# 'dsos' contains a record for each executable file or library. 113# 114# machines 115# 116# 'machines' can be used to distinguish virtual machines if virtualization is supported. 117# 118# selected_events 119# 120# 'selected_events' contains a record for each kind of event that has been sampled. 121# 122# symbols 123# 124# 'symbols' contains a record for each symbol. Only symbols that have samples are present. 125# 126# threads 127# 128# 'threads' contains a record for each thread. 129# 130# Views: 131# 132# Most of the tables have views for more friendly display. The views are: 133# 134# calls_view 135# call_paths_view 136# comm_threads_view 137# dsos_view 138# machines_view 139# samples_view 140# symbols_view 141# threads_view 142# 143# More examples of browsing the database with psql: 144# Note that some of the examples are not the most optimal SQL query. 145# Note that call information is only available if the script's 'calls' option has been used. 146# 147# Top 10 function calls (not aggregated by symbol): 148# 149# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10; 150# 151# Top 10 function calls (aggregated by symbol): 152# 153# SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol, 154# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count 155# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10; 156# 157# Note that the branch count gives a rough estimation of cpu usage, so functions 158# that took a long time but have a relatively low branch count must have spent time 159# waiting. 160# 161# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'): 162# 163# SELECT * FROM symbols_view WHERE name LIKE '%alloc%'; 164# 165# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187): 166# 167# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10; 168# 169# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254): 170# 171# SELECT * FROM calls_view WHERE parent_call_path_id = 254; 172# 173# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670) 174# 175# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%'; 176# 177# Show transactions: 178# 179# SELECT * FROM samples_view WHERE event = 'transactions'; 180# 181# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false. 182# Transaction aborts have branch_type_name 'transaction abort' 183# 184# Show transaction aborts: 185# 186# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort'; 187# 188# To print a call stack requires walking the call_paths table.
