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
38 # $ sudo su - postgres
39 # $ createuser <your user id here>
40 # Shall the new role be a superuser? (y/n) y
42 # An example of using this script with Intel PT:

54 # To browse the database, psql can be used e.g.
57 # pt_example=# select * from samples_view where id < 100;
59 # pt_example=# \d+ samples_view
62 # An example of using the database is provided by the script
63 # call-graph-from-postgresql.py. Refer to that script for details.
67 # The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
71 # 'samples' is the main table. It represents what instruction was executing at a point in time
72 # when something (a selected event) happened. The memory address is the instruction pointer or 'ip'.
76 # 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
77 # 'calls' is only created when the 'calls' option to this script is specified.
81 # 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'.
82 # 'calls_paths' is only created when the 'calls' option to this script is specified.
86 # 'branch_types' provides descriptions for each type of branch.
90 # 'comm_threads' shows how 'comms' relates to 'threads'.
94 # 'comms' contains a record for each 'comm' - the name given to the executable that is running.
98 # 'dsos' contains a record for each executable file or library.
102 # 'machines' can be used to distinguish virtual machines if virtualization is supported.
106 # 'selected_events' contains a record for each kind of event that has been sampled.
110 # 'symbols' contains a record for each symbol. Only symbols that have samples are present.
114 # 'threads' contains a record for each thread.
118 # Most of the tables have views for more friendly display. The views are:
129 # More examples of browsing the database with psql:
130 # Note that some of the examples are not the most optimal SQL query.
131 # Note that call information is only available if the script's 'calls' option has been used.
133 # Top 10 function calls (not aggregated by symbol):
135 # SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
137 # Top 10 function calls (aggregated by symbol):
139 # SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
140 # SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
141 # FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
143 # Note that the branch count gives a rough estimation of cpu usage, so functions
144 # that took a long time but have a relatively low branch count must have spent time
147 # Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
149 # SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
151 # Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
153 # SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
155 # Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
157 # SELECT * FROM calls_view WHERE parent_call_path_id = 254;
159 # Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
161 # SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
165 # SELECT * FROM samples_view WHERE event = 'transactions';
167 # Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
168 # Transaction aborts have branch_type_name 'transaction abort'
170 # Show transaction aborts:
172 # SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
174 # To print a call stack requires walking the call_paths table. For example this python script:
178 # from PySide.QtSql import *
180 # if __name__ == '__main__':
181 # if (len(sys.argv) < 3):
