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.
23#
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:
27#
28# fedora:
29#
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
37#
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
42#
43# ubuntu:
44#
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
49#
50# Alternately, to use Python3 and/or pyside 2, one of the following:
51#
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
55#
56# An example of using this script with Intel PT:
57#
58# $ perf record -e intel_pt//u ls
59# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

66# 2015-05-29 12:49:29.365350 Done
67#
68# To browse the database, psql can be used e.g.
69#
70# $ psql pt_example
71# pt_example=# select * from samples_view where id < 100;
72# pt_example=# \d+
73# pt_example=# \d+ samples_view
74# pt_example=# \q
75#
76# An example of using the database is provided by the script
77# exported-sql-viewer.py. Refer to that script for details.
78#
79# Tables:
80#
81# The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
82#
83# samples
84#
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'.
87#
88# calls
89#
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.
92#
93# call_paths
94#
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.
97#
98# branch_types
99#
100# 'branch_types' provides descriptions for each type of branch.
101#
102# comm_threads
103#
104# 'comm_threads' shows how 'comms' relates to 'threads'.
105#
106# comms
107#
108# 'comms' contains a record for each 'comm' - the name given to the executable that is running.
109#
110# dsos
111#
112# 'dsos' contains a record for each executable file or library.
113#
114# machines
115#
116# 'machines' can be used to distinguish virtual machines if virtualization is supported.
117#
118# selected_events
119#
120# 'selected_events' contains a record for each kind of event that has been sampled.
121#
122# symbols
123#
124# 'symbols' contains a record for each symbol. Only symbols that have samples are present.
125#
126# threads
127#
128# 'threads' contains a record for each thread.
129#
130# Views:
131#
132# Most of the tables have views for more friendly display. The views are:
133#
134# calls_view
135# call_paths_view
136# comm_threads_view
137# dsos_view
138# machines_view
139# samples_view
140# symbols_view
141# threads_view
142#
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.
146#
147# Top 10 function calls (not aggregated by symbol):
148#
149# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
150#
151# Top 10 function calls (aggregated by symbol):
152#
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;
156#
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
159# waiting.
160#
161# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
162#
163# SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
164#
165# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
166#
167# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
168#
169# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
170#
171# SELECT * FROM calls_view WHERE parent_call_path_id = 254;
172#
173# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
174#
175# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
176#
177# Show transactions:
178#
179# SELECT * FROM samples_view WHERE event = 'transactions';
180#
181# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
182# Transaction aborts have branch_type_name 'transaction abort'
183#
184# Show transaction aborts:
185#
186# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
187#
188# To print a call stack requires walking the call_paths table. For example this python script:
189# #!/usr/bin/python2
190#
191# import sys
192# from PySide.QtSql import *
