20 # To use this script you will need to have installed package python-pyside which
21 # provides LGPL-licensed Python bindings for Qt. You will also need the package
22 # libqt4-sql-psql for Qt postgresql support.
24 # The script assumes postgresql is running on the local machine and that the
25 # user has postgresql permissions to create databases. Examples of installing
26 # postgresql and adding such a user are:
30 # $ sudo yum install postgresql postgresql-server qt-postgresql
31 # $ sudo su - postgres -c initdb
32 # $ sudo service postgresql start
33 # $ sudo su - postgres
34 # $ createuser -s <your user id here> # Older versions may not support -s, in which case answer the prompt below:
35 # Shall the new role be a superuser? (y/n) y
36 # $ sudo yum install python-pyside
38 # Alternately, to use Python3 and/or pyside 2, one of the following:
39 # $ sudo yum install python3-pyside
40 # $ pip install --user PySide2
41 # $ pip3 install --user PySide2
45 # $ sudo apt-get install postgresql
46 # $ sudo su - postgres
47 # $ createuser -s <your user id here>
48 # $ sudo apt-get install python-pyside.qtsql libqt4-sql-psql
50 # Alternately, to use Python3 and/or pyside 2, one of the following:
52 # $ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql
53 # $ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql
54 # $ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql
56 # An example of using this script with Intel PT:

68 # To browse the database, psql can be used e.g.
71 # pt_example=# select * from samples_view where id < 100;
73 # pt_example=# \d+ samples_view
76 # An example of using the database is provided by the script
77 # exported-sql-viewer.py. Refer to that script for details.
81 # The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
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'.
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.
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.
100 # 'branch_types' provides descriptions for each type of branch.
104 # 'comm_threads' shows how 'comms' relates to 'threads'.
108 # 'comms' contains a record for each 'comm' - the name given to the executable that is running.
112 # 'dsos' contains a record for each executable file or library.
116 # 'machines' can be used to distinguish virtual machines if virtualization is supported.
120 # 'selected_events' contains a record for each kind of event that has been sampled.
124 # 'symbols' contains a record for each symbol. Only symbols that have samples are present.
128 # 'threads' contains a record for each thread.
132 # Most of the tables have views for more friendly display. The views are:
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.
147 # Top 10 function calls (not aggregated by symbol):
149 # SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
151 # Top 10 function calls (aggregated by symbol):
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;
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
161 # Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
163 # SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
165 # Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
167 # SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
169 # Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
171 # SELECT * FROM calls_view WHERE parent_call_path_id = 254;
173 # Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
175 # SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
179 # SELECT * FROM samples_view WHERE event = 'transactions';
181 # Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
182 # Transaction aborts have branch_type_name 'transaction abort'
184 # Show transaction aborts:
186 # SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
