  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

  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 # exported-sql-viewer.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 #

 174 #   #!/usr/bin/python2
