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.
21#
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:
25#
26# fedora:
27#
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
34#
35# ubuntu:
36#
37# $ sudo apt-get install postgresql python-pyside.qtsql libqt4-sql-psql
38# $ sudo su - postgres
39# $ createuser -s <your user id here>
40#
41# An example of using this script with Intel PT:
42#
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

51# 2015-05-29 12:49:29.365350 Done
52#
53# To browse the database, psql can be used e.g.
54#
55# $ psql pt_example
56# pt_example=# select * from samples_view where id < 100;
57# pt_example=# \d+
58# pt_example=# \d+ samples_view
59# pt_example=# \q
60#
61# An example of using the database is provided by the script
62# call-graph-from-postgresql.py. Refer to that script for details.
63#
64# Tables:
65#
66# The tables largely correspond to perf tools' data structures. 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. For example this python script:
174# #!/usr/bin/python2
175#
176# import sys
177# from PySide.QtSql import *
