Points to note:

+
    +
  • The top level is a command name (comm)
    • +
  • The next level is a thread (pid:tid)
    • +
  • Subsequent levels are functions
    • +
  • 'Count' is the number of calls
    • +
  • 'Time' is the elapsed time until the function returns
    • +
  • Percentages are relative to the level above
    • +
  • 'Branch Count' is the total number of branches for that function and all functions that it calls +
+

Find

+Ctrl-F displays a Find bar which finds function names by either an exact match or a pattern match. +The pattern matching symbols are ? for any character and * for zero or more characters. +

1.2 Call Tree

+The Call Tree report is very similar to the Context-Sensitive Call Graph, but the data is not aggregated. +Also the 'Count' column, which would be always 1, is replaced by the 'Call Time'. +

1.3 All branches

+The All branches report displays all branches in chronological order. +Not all data is fetched immediately. More records can be fetched using the Fetch bar provided. +

Disassembly

+Open a branch to display disassembly. This only works if: +
    +
  1. The disassembler is available. Currently, only Intel XED is supported - see Intel XED Setup
    2. +
  2. The object code is available. Currently, only the perf build ID cache is searched for object code. +The default directory ~/.debug can be overridden by setting environment variable PERF_BUILDID_DIR. +One exception is kcore where the DSO long name is used (refer dsos_view on the Tables menu), +or alternatively, set environment variable PERF_KCORE to the kcore file name.

Intel XED Setup

+To use Intel XED, libxed.so must be present. To build and install libxed.so: +
+git clone https://github.com/intelxed/mbuild.git mbuild
+git clone https://github.com/intelxed/xed
+cd xed
+./mfile.py --share
+sudo ./mfile.py --prefix=/usr/local install
+sudo ldconfig
+
+

Instructions per Cycle (IPC)

+If available, IPC information is displayed in columns 'insn_cnt', 'cyc_cnt' and 'IPC'. +

Intel PT note: The information applies to the blocks of code ending with, and including, that branch. +Due to the granularity of timing information, the number of cycles for some code blocks will not be known. +In that case, 'insn_cnt', 'cyc_cnt' and 'IPC' are zero, but when 'IPC' is displayed it covers the period +since the previous displayed 'IPC'. +

Find

+Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match. +Refer to Python documentation for the regular expression syntax. +All columns are searched, but only currently fetched rows are searched. +

1.4 Selected branches

+This is the same as the All branches report but with the data reduced +by various selection criteria. A dialog box displays available criteria which are AND'ed together. +

1.4.1 Time ranges

+The time ranges hint text shows the total time range. Relative time ranges can also be entered in +ms, us or ns. Also, negative values are relative to the end of trace. Examples: +
+	81073085947329-81073085958238	From 81073085947329 to 81073085958238
+	100us-200us		From 100us to 200us
+	10ms-			From 10ms to the end
+	-100ns			The first 100ns
+	-10ms-			The last 10ms
+
+N.B. Due to the granularity of timestamps, there could be no branches in any given time range. +

1.5 Top calls by elapsed time

+The Top calls by elapsed time report displays calls in descending order of time elapsed between when the function was called and when it returned. +The data is reduced by various selection criteria. A dialog box displays available criteria which are AND'ed together. +If not all data is fetched, a Fetch bar is provided. Ctrl-F displays a Find bar. +

2. Charts

+

2.1 Time chart by CPU

+This chart displays context switch information when that data is available. Refer to context_switches_view on the Tables menu. +

Features

+
    +
  1. Mouse over to highight the task and show the time
    2. +
  2. Drag the mouse to select a region and zoom by pushing the Zoom button
    3. +
  3. Go back and forward by pressing the arrow buttons
    4. +
  4. If call information is available, right-click to show a call tree opened to that task and time. +Note, the call tree may take some time to appear, and there may not be call information for the task or time selected. +
    5. +
+

Important

+The graph can be misleading in the following respects: +
    +
  1. The graph shows the first task on each CPU as running from the beginning of the time range. +Because tracing might start on different CPUs at different times, that is not necessarily the case. +Refer to context_switches_view on the Tables menu to understand what data the graph is based upon.
    2. +
  2. Similarly, the last task on each CPU can be showing running longer than it really was. +Again, refer to context_switches_view on the Tables menu to understand what data the graph is based upon.
    3. +
  3. When the mouse is over a task, the highlighted task might not be visible on the legend without scrolling if the legend does not fit fully in the window
    4. +
+

3. Tables

+The Tables menu shows all tables and views in the database. Most tables have an associated view +which displays the information in a more friendly way. Not all data for large tables is fetched +immediately. More records can be fetched using the Fetch bar provided. Columns can be sorted, +but that can be slow for large tables. +

There are also tables of database meta-information. +For SQLite3 databases, the sqlite_master table is included. +For PostgreSQL databases, information_schema.tables/views/columns are included. +

Find

+Ctrl-F displays a Find bar which finds substrings by either an exact match or a regular expression match. +Refer to Python documentation for the regular expression syntax. +All columns are searched, but only currently fetched rows are searched. +

N.B. Results are found in id order, so if the table is re-ordered, find-next and find-previous +will go to the next/previous result in id order, instead of display order. +""" + +# Help window + +class HelpWindow(QMdiSubWindow): + + def __init__(self, glb, parent=None): + super(HelpWindow, self).__init__(parent) + + self.text = QTextBrowser() + self.text.setHtml(glb_help_text) + self.text.setReadOnly(True) + self.text.setOpenExternalLinks(True) + + self.setWidget(self.text) + + AddSubWindow(glb.mainwindow.mdi_area, self, "Exported SQL Viewer Help") + +# Main window that only displays the help text + +class HelpOnlyWindow(QMainWindow): + + def __init__(self, parent=None): + super(HelpOnlyWindow, self).__init__(parent) + + self.setMinimumSize(200, 100) + self.resize(800, 600) + self.setWindowTitle("Exported SQL Viewer Help") + self.setWindowIcon(self.style().standardIcon(QStyle.SP_MessageBoxInformation)) + + self.text = QTextBrowser() + self.text.setHtml(glb_help_text) + self.text.setReadOnly(True) + self.text.setOpenExternalLinks(True) + + self.setCentralWidget(self.text) + +# PostqreSQL server version + +def PostqreSQLServerVersion(db): + query = QSqlQuery(db) + QueryExec(query, "SELECT VERSION()") + if query.next(): + v_str = query.value(0) + v_list = v_str.strip().split(" ") + if v_list[0] == "PostgreSQL" and v_list[2] == "on": + return v_list[1] + return v_str + return "Unknown" + +# SQLite version + +def SQLiteVersion(db): + query = QSqlQuery(db) + QueryExec(query, "SELECT sqlite_version()") + if query.next(): + return query.value(0) + return "Unknown" + +# About dialog + +class AboutDialog(QDialog): + + def __init__(self, glb, parent=None): + super(AboutDialog, self).__init__(parent) + + self.setWindowTitle("About Exported SQL Viewer") + self.setMinimumWidth(300) + + pyside_version = "1" if pyside_version_1 else "2" + + text = "
