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.
