18 # To use this script you will need to have installed package python-pyside which
19 # provides LGPL-licensed Python bindings for Qt. You will also need the package
20 # libqt4-sql-psql for Qt postgresql support.
22 # The script assumes postgresql is running on the local machine and that the
23 # user has postgresql permissions to create databases. Examples of installing
24 # postgresql and adding such a user are:
28 # $ sudo yum install postgresql postgresql-server python-pyside qt-postgresql
29 # $ sudo su - postgres -c initdb
30 # $ sudo service postgresql start
31 # $ sudo su - postgres
32 # $ createuser <your user id here>
33 # Shall the new role be a superuser? (y/n) y
37 # $ sudo apt-get install postgresql python-pyside.qtsql libqt4-sql-psql
38 # $ sudo su - postgres
39 # $ createuser -s <your user id here>
41 # An example of using this script with Intel PT:
43 # $ perf record -e intel_pt//u ls
44 # $ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

53 # To browse the database, psql can be used e.g.
56 # pt_example=# select * from samples_view where id < 100;
58 # pt_example=# \d+ samples_view
61 # An example of using the database is provided by the script
62 # exported-sql-viewer.py. Refer to that script for details.
66 # The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
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'.
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.
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.
85 # 'branch_types' provides descriptions for each type of branch.
89 # 'comm_threads' shows how 'comms' relates to 'threads'.
93 # 'comms' contains a record for each 'comm' - the name given to the executable that is running.
97 # 'dsos' contains a record for each executable file or library.
101 # 'machines' can be used to distinguish virtual machines if virtualization is supported.
105 # 'selected_events' contains a record for each kind of event that has been sampled.
109 # 'symbols' contains a record for each symbol. Only symbols that have samples are present.
113 # 'threads' contains a record for each thread.
117 # Most of the tables have views for more friendly display. The views are:
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.
132 # Top 10 function calls (not aggregated by symbol):
134 # SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
136 # Top 10 function calls (aggregated by symbol):
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;
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
146 # Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
148 # SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
150 # Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
152 # SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
154 # Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
156 # SELECT * FROM calls_view WHERE parent_call_path_id = 254;
158 # Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
160 # SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
164 # SELECT * FROM samples_view WHERE event = 'transactions';
166 # Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
167 # Transaction aborts have branch_type_name 'transaction abort'
169 # Show transaction aborts:
171 # SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
173 # To print a call stack requires walking the call_paths table. For example this python script:
