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-sql.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 *
