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
38# $ sudo su - postgres
39# $ createuser <your user id here>
40# Shall the new role be a superuser? (y/n) y
41#
42# An example of using this script with Intel PT:
43#
44# $ perf record -e intel_pt//u ls
45# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls

54# To browse the database, psql can be used e.g.
55#
56# $ psql pt_example
57# pt_example=# select * from samples_view where id < 100;
58# pt_example=# \d+
59# pt_example=# \d+ samples_view
60# pt_example=# \q
61#
62# An example of using the database is provided by the script
63# call-graph-from-postgresql.py. Refer to that script for details.
64#
65# Tables:
66#
67# The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
68#
69# samples
70#
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'.
73#
74# calls
75#
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.
78#
79# call_paths
80#
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.
83#
84# branch_types
85#
86# 'branch_types' provides descriptions for each type of branch.
87#
88# comm_threads
89#
90# 'comm_threads' shows how 'comms' relates to 'threads'.
91#
92# comms
93#
94# 'comms' contains a record for each 'comm' - the name given to the executable that is running.
95#
96# dsos
97#
98# 'dsos' contains a record for each executable file or library.
99#
100# machines
101#
102# 'machines' can be used to distinguish virtual machines if virtualization is supported.
103#
104# selected_events
105#
106# 'selected_events' contains a record for each kind of event that has been sampled.
107#
108# symbols
109#
110# 'symbols' contains a record for each symbol. Only symbols that have samples are present.
111#
112# threads
113#
114# 'threads' contains a record for each thread.
115#
116# Views:
117#
118# Most of the tables have views for more friendly display. The views are:
119#
120# calls_view
121# call_paths_view
122# comm_threads_view
123# dsos_view
124# machines_view
125# samples_view
126# symbols_view
127# threads_view
128#
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.
132#
133# Top 10 function calls (not aggregated by symbol):
134#
135# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
136#
137# Top 10 function calls (aggregated by symbol):
138#
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;
142#
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
145# waiting.
146#
147# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
148#
149# SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
150#
151# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
152#
153# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
154#
155# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
156#
157# SELECT * FROM calls_view WHERE parent_call_path_id = 254;
158#
159# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
160#
161# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
162#
163# Show transactions:
164#
165# SELECT * FROM samples_view WHERE event = 'transactions';
166#
167# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
168# Transaction aborts have branch_type_name 'transaction abort'
169#
170# Show transaction aborts:
171#
172# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
173#
174# To print a call stack requires walking the call_paths table. For example this python script:
175# #!/usr/bin/python2
176#
177# import sys
178# from PySide.QtSql import *
