You will also need the package# libqt4-sql-psql for Qt postgresql support.## The script assumes postgresql is running on the local machine and that the# user has postgresql permissions to create databases. Examples of installing# postgresql and adding such a user are:## fedora:## $ sudo yum install postgresql postgresql-server qt-postgresql# $ sudo su - postgres -c initdb# $ sudo service postgresql start# $ sudo su - postgres# $ createuser -s <your user id here> # Older versions may not support -s, in which case answer the prompt below:# Shall the new role be a superuser? (y/n) y# $ sudo yum install python-pyside## Alternately, to use Python3 and/or pyside 2, one of the following:# $ sudo yum install python3-pyside# $ pip install --user PySide2# $ pip3 install --user PySide2## ubuntu:## $ sudo apt-get install postgresql# $ sudo su - postgres# $ createuser -s <your user id here># $ sudo apt-get install python-pyside.qtsql libqt4-sql-psql## Alternately, to use Python3 and/or pyside 2, one of the following:## $ sudo apt-get install python3-pyside.qtsql libqt4-sql-psql# $ sudo apt-get install python-pyside2.qtsql libqt5sql5-psql# $ sudo apt-get install python3-pyside2.qtsql libqt5sql5-psql## An example of using this script with Intel PT:## $ perf record -e intel_pt//u ls# $ perf script -s ~/libexec/perf-core/scripts/python/export-to-postgresql.py pt_example branches calls# 2015-05-29 12:49:23.464364 Creating database...# 2015-05-29 12:49:26.281717 Writing to intermediate files...# 2015-05-29 12:49:27.190383 Copying to database...# 2015-05-29 12:49:28.140451 Removing intermediate files...# 2015-05-29 12:49:28.147451 Adding primary keys# 2015-05-29 12:49:28.655683 Adding foreign keys# 2015-05-29 12:49:29.365350 Done## To browse the database, psql can be used e.g.## $ psql pt_example# pt_example=# select * from samples_view where id < 100;# pt_example=# \d+# pt_example=# \d+ samples_view# pt_example=# \q## An example of using the database is provided by the script# exported-sql-viewer.py. Refer to that script for details.## Tables:## The tables largely correspond to perf tools' data structures. They are largely self-explanatory.## samples## 'samples' is the main table. It represents what instruction was executing at a point in time# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'.## calls## 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.# 'calls' is only created when the 'calls' option to this script is specified.## call_paths## 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'.# 'calls_paths' is only created when the 'calls' option to this script is specified.## branch_types## 'branch_types' provides descriptions for each type of branch.## comm_threads## 'comm_threads' shows how 'comms' relates to 'threads'.## comms## 'comms' contains a record for each 'comm' - the name given to the executable that is running.## dsos## 'dsos' contains a record for each executable file or library.## machines## 'machines' can be used to distinguish virtual machines if virtualization is supported.## selected_events## 'selected_events' contains a record for each kind of event that has been sampled.## symbols## 'symbols' contains a record for each symbol. Only symbols that have samples are present.## threads## 'threads' contains a record for each thread.## Views:## Most of the tables have views for more friendly display. The views are:## calls_view# call_paths_view# comm_threads_view# dsos_view# machines_view# samples_view# symbols_view# threads_view## More examples of browsing the database with psql:# Note that some of the examples are not the most optimal SQL query.# Note that call information is only available if the script's 'calls' option has been used.## Top 10 function calls (not aggregated by symbol):## SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;## Top 10 function calls (aggregated by symbol):## SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;## Note that the branch count gives a rough estimation of cpu usage, so functions# that took a long time but have a relatively low branch count must have spent time# waiting.## Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):## SELECT * FROM symbols_view WHERE name LIKE '%alloc%';## Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):## SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;## Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):## SELECT * FROM calls_view WHERE parent_call_path_id = 254;## Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)## SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';## Show transactions:## SELECT * FROM samples_view WHERE event = 'transactions';## Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.# Transaction aborts have branch_type_name 'transaction abort'## Show transaction aborts:## SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';## To print a call stack requires walking the call_paths table.
