Sun Studio 12 Update 1: Performance Analyzer

Performance Analyzer GUI

The Analyzer window has a menu bar, a tool bar, and a split pane that contains tabs for the various data displays.

The Menu Bar

The menu bar contains a File menu, a View menu, a Timeline menu, and a Help menu.

The File menu is for opening, adding, and dropping experiments and experiment groups. The File menu allows you to collect data for an experiment using the Performance Analyzer GUI. For details on using the Performance Analyzer to collect data, refer to Recording Experiments. From the File menu, you can also create a mapfile, which is used to optimize the size of an executable or optimize its effective cache behavior. For more details on mapfiles, refer to Generating Mapfiles and Function Reordering.

The View menu allows you to configure how experiment data is displayed.

The Timeline menu, as its name suggests, helps you to navigate the timeline display, described in Analyzer Data Displays.

The Help menu provides online help for the Performance Analyzer, provides a summary of new features, has quick-reference and shortcut sections, and has a troubleshooting section.

The Toolbar

The toolbar provides sets of icons as shortcuts, and includes a Find function to help you locate text or highlighted lines in the tabs. For more details about the Find function, refer to Finding Text and Data

Analyzer Data Displays

The Performance Analyzer uses a split-window to divide the data presentation into two panes. Each pane is tabbed to allow you to select different data displays for the same experiment or experiment group.

Data Display, Left Pane

The left pane displays tabs for the principal Analyzer displays in the order in which they appear:

If you invoke the Analyzer without a target, you are prompted for an experiment to open.

By default, the first visible tab is selected. Only tabs applicable to the data in the loaded experiments are displayed.

Whether a tab is displayed in the left pane of Analyzer window when you open an experiment is determined by a tabs directive in the .er.rc files read when you start the Analyzer and the applicability of the tab to the data in the experiment. You can use the Tabs tab in the Set Data Presentation dialog box (see Tabs Tab) to select the tabs you want to display for an experiment.

The MPI Timeline Tab

The MPI Timeline tab shows a set of horizontal bars, one for each process in the MPI experiment, with diagonal lines connecting them indicating messages. Each bar has regions colored according to the MPI function they are in, or indicating that the process is not within MPI (that is, it is elsewhere in the application code).

Selecting a region of a bar or a message line shows detailed information about the selection in the MPI Timeline Controls tab.

Dragging the mouse causes the MPI Timeline tab to zoom in on the horizontal (time) axis or the vertical (process) axis, depending on the predominant direction of the drag.

MPI Chart Tab

The MPI Chart tab shows charts of the MPI tracing data displayed in the MPI Timeline tab. It displays plots of data concerning MPI execution. Changing the controls in the MPI Chart tab and clicking Redraw causes a new chart to be displayed. Selecting an element from a chart shows more detailed information about that element in the MPI Chart Controls tab.

Dragging the mouse causes the MPI Chart tab to zoom in on the rectangular area defined by the drag.

The Races Tab

The Races tab shows a list of all the data races detected in a data-race experiment. For more information, see Sun Studio 12: Thread Analyzer User’s Guide.

The Deadlocks tab

The Deadlocks tab shows a list of all the deadlocks detected in a deadlock experiment. For more information, see Sun Studio 12: Thread Analyzer User’s Guide.

The Functions Tab

The Functions tab shows a list consisting of functions and their metrics. The metrics are derived from the data collected in the experiment. Metrics can be either exclusive or inclusive. Exclusive metrics represent usage within the function itself. Inclusive metrics represent usage within the function and all the functions it called.

The list of available metrics for each kind of data collected is given in the collect(1) man page. Only the functions that have non-zero metrics are listed.

Time metrics are shown as seconds, presented to millisecond precision. Percentages are shown to a precision of 0.01%. If a metric value is precisely zero, its time and percentage is shown as “0.” If the value is not exactly zero, but is smaller than the precision, its value is shown as “0.000” and its percentage as “0.00”. Because of rounding, percentages may not sum to exactly 100%. Count metrics are shown as an integer count.

The metrics initially shown are based on the data collected and on the default settings read from various .er.rc files. When the Performance Analyzer is initially installed, the defaults are as follows:

If more than one type of data has been collected, the default metrics for each type are shown.

The metrics that are shown can be changed or reorganized; see the online help for details.

To search for a function, use the Find tool. For further details about the Find tool, refer to Finding Text and Data.

To select a single function, click on that function.

To select several functions that are displayed contiguously in the tab, select the first function of the group, then Shift-click on the last function of the group.

To select a several functions that are not displayed contiguously in the tab, select the first function of the group, then select the additional functions by Ctrl-clicking on each function.

When you click the Compose Filter Clause button on the toolbar, the Filter dialog box opens with Advanced tab selected and the Filter clause text box loaded with a filter clause that reflects the selection(s) in the Functions tab.

The Callers-Callees Tab

The Callers-Callees tab shows the selected function in a pane in the center, with callers of that function in a pane above, and callees of that function in a pane below.

In addition to showing exclusive and inclusive metric values for each function, the tab also shows attributed metrics. For the selected function, the attributed metric represents the exclusive metric for that function. For the callees, the attribute metric represents the portion of the callee’s inclusive metric that is attributable to calls from the center function. The sum of attributed metrics for the callees and the selected function will add up to the inclusive metric for the selected function.

For the callers, the attributed metrics represent the portion of the selected function’s inclusive metric that is attributable to calls from the callers. The sum of the attributed metrics for all callers should also add up to the inclusive metric for the selected function.

The metrics shown in the Callers-Callees tab can be changed or reorganized; see the online help for details.

Clicking once on a function in the caller or callee pane selects that function, causing the window contents to be redrawn so that the selected function appears in the center pane.

The Dual-Source Tab

The Dual-Source tab shows the two source contexts involved in the selected data race or deadlock. The tab is shown only if data-race-detection or deadlock experiments are loaded.

The Source-Disassembly Tab

The Source-Disassembly tab shows the annotated source in an upper pane, and the annotated disassembly in a lower pane. The tab is not visible by default. Use the Set Data Presentation option on the View menu to add the Source-Disassembly tab.

The Source Tab

If available, the Source tab shows the file containing the source code of the selected function, annotated with performance metrics for each source line. The full names of the source file, the corresponding object file and the load object are given in the column heading for the source code. In the rare case where the same source file is used to compile more than one object file, the Source tab shows the performance data for the object file containing the selected function.

The Analyzer looks for the file containing the selected function under the absolute pathname as recorded in the executable. If the file is not there, the Analyzer tries to find a file of the same basename in the current working directory. If you have moved the sources, or the experiment was recorded in a different file system, you can put a symbolic link in the current directory to the original path name in order to see the annotated source. You can also use settings in the Set Data Presentation dialog box: the Search Path tab (see Search Path Tab) lets you manage a list of directories to be used for searching for source files, the Pathmaps tab (see Pathmaps Tab) enables you to map the leading part of a file path from one location to another.

When you select a function in the Functions tab and the Source tab is opened, the source file displayed is the default source context for that function. The default source context of a function is the file containing the function’s first instruction, which for C code is the function’s opening brace. Immediately following the first instruction, the annotated source file adds an index line for the function. The source window displays index lines as text in red italics within angle brackets in the form:

<Function: f_name>

A function might have an alternate source context, which is another file that contains instructions attributed to the function. Such instructions might come from include files or from other functions inlined into the selected function. If there are any alternate source contexts, the beginning of the default source context includes a list of extended index lines that indicate where the alternate source contexts are located.

<Function: f, instructions from source file src.h>

Double clicking on an index line that refers to another source context opens the file containing that source context, at the location associated with the indexed function.

To aid navigation, alternate source contexts also start with a list of index lines that refer back to functions defined in the default source context and other alternate source contexts.

The source code is interleaved with any compiler commentary that has been selected for display. The classes of commentary shown can be set in the Set Data Presentation dialog box. The default classes can be set in a .er.rc defaults file.

The metrics displayed in the Source tab can be changed or reorganized; see the online help for details.

Lines with metrics that are equal to or exceed a threshold percentage of the maximum of that metric for any line in the source file are highlighted to make it easier to find the important lines. The threshold can be set in the Set Data Presentation dialog box. The default threshold can be set in a .er.rc defaults file. Tick marks are shown next to the scrollbar, corresponding to the position of over-threshold lines within the source file. For example, if there were two over-threshold lines near the end of the source file, two ticks would be shown next to the scrollbar near the bottom of the source window. Positioning the scrollbar next to a tick mark will position the source lines displayed in the source window so that the corresponding over-threshold line is displayed.

The Lines Tab

The Lines tab shows a list consisting of source lines and their metrics. Source lines are labeled with the function from which they came and the line number and source file name. If no line-number information is available for a function, or the source file for the function is not known, all of the function’s program counters (PCs) appear aggregated into a single entry for the function in the lines display. PCs from functions that are from load-objects whose functions are hidden appear aggregated as a single entry for the load-object in the lines display. Selecting a line in the Lines tab shows all the metrics for that line in the Summary tab. Selecting the Source or Disassembly tab after selecting a line from the Lines tab positions the display at the appropriate line.

The Disassembly Tab

The Disassembly tab shows a disassembly listing of the object file containing the selected function, annotated with performance metrics for each instruction.

Interleaved within the disassembly listing is the source code, if available, and any compiler commentary chosen for display. The algorithm for finding the source file in the Disassembly tab is the same as the algorithm used in the Source tab.

Just as with the Source tab, index lines are displayed in Disassembly tab. But unlike with the Source tab, index lines for alternate source contexts cannot be used directly for navigation purposes. Also, index lines for alternate source contexts are displayed at the start of where the #included or inlined code is inserted, rather than just being listed at the beginning of the Disassembly view. Code that is #included or inlined from other files shows as raw disassembly instructions without interleaving the source code. However, placing the cursor on one of these instructions and selecting the Source tab opens the source file containing the #included or inlined code. Selecting the Disassembly tab with this file displayed opens the Disassembly view in the new context, thus displaying the disassembly code with interleaved source code.

The classes of commentary shown can be set in the Set Data Presentation dialog box. The default classes can be set in a .er.rc defaults file.

The Analyzer highlights lines with metrics that are equal to or exceed a metric-specific threshold, to make it easier to find the important lines. You can set the threshold in the Set Data Presentation dialog box. You can set the default threshold in a .er.rc defaults file. As with the Source tab, tick marks are shown next to the scrollbar, corresponding to the position of over-threshold lines within the disassembly code.

The PCs Tab

The PCs tab shows a list consisting of program counters (PCs) and their metrics. PCs are labeled with the function from which they came and the offset within that function. PCs from functions that are from load-objects whose functions are hidden appear aggregated as a single entry for the load-object in the PCs display. Selecting a line in the PCs tab shows all the metrics for that PC in the Summary tab. Selecting the Source tab or Disassembly tab after selecting a line from the PCs tab positions the display at the appropriate line.

See the section Call Stacks and Program Execution for more information about PCs.

The OpenMP Parallel Region Tab

The OpenMP Parallel Region tab shows the list of OpenMP parallel regions with their metrics. The tab is applicable only to experiments recorded with the OpenMP 3.0 collector.

The OpenMP Task Tab

The OpenMP Task tab shows the list of OpenMP tasks with their metrics. The tab is applicable only to experiments recorded with the OpenMP 3.0 collector.

The Timeline Tab

The Timeline tab shows a chart of the events and the sample points recorded by the Collector as a function of time. Data is displayed in horizontal bars. For each experiment there is a bar for sample data and a set of bars for each LWP. The set for an LWP consists of one bar for each data type recorded: clock-based profiling, hardware counter overflow profiling, synchronization tracing, heap tracing, and MPI tracing.

The bars that contain sample data show a color-coded representation of the time spent in each microstate for each sample. Samples are displayed as a period of time because the data in a sample point represents time spent between that point and the previous point. Clicking a sample displays the data for that sample in the Event tab.

The profiling data or tracing data bars show an event marker for each event recorded. The event markers consist of a color-coded representation of the call stack recorded with the event, as a stack of colored rectangles. Clicking a colored rectangle in an event marker selects the corresponding function and PC and displays the data for that event and that function in the Event tab. The selection is highlighted in both the Event tab and the Legend tab, and selecting the Source tab or Disassembly tab positions the tab display at the line corresponding to that frame in the call stack.

For some kinds of data, events may overlap and not be visible. Whenever two or more events would appear at exactly the same position, only one is drawn; if there are two or more events within one or two pixels, all are drawn. although they may not be visually distinguishable. In either case, a small gray tick mark is displayed below the drawn events indicating the overlap.

The Timeline tab of the Set Data Presentation dialog box allows you to change the types of event-specific data that are shown; to select the display of event-specific data for threads, LWPs, or CPUs; to choose to align the call stack representation at the root or at the leaf; and to choose the number of levels of the call stack that are displayed.

You can change the types of event-specific data shown in the Timeline tab, as well as the colors mapped to selected functions. For details about using the Timeline tab, refer to the online help.

The LeakList Tab

The LeakList tab shows two lines, the upper one representing leaks, and the lower one representing allocations. Each contains a call stack, similar to that shown in the Timeline tab, in the center with a bar above proportional to the bytes leaked or allocated, and a bar below proportional to the number of leaks or allocations.

Selection of a leak or allocation displays the data for the selected leak or allocation in the Leak tab, and selects a frame in the call stack, just as it does in the Timeline tab.

You can display the LeakList tab by selecting it in the Tabs tab of the Set Data Presentation dialog box (see Tabs Tab). You can make the LeakList tab visible only if one or more of the loaded experiments contains heap trace data.

The DataObjects Tab

The DataObjects tab shows the list of data objects with their metrics. The tab is applicable only to hardware counter overflow experiments where the aggressive backtracking option was enabled, and for source files that were compiled with the -xhwcprof option in the C compiler.

You can display the tab by selecting it in the Tabs tab of the Set Data Presentation dialog box (see Tabs Tab). You can make the DataObjects tab visible only if one or more of the loaded experiments contains a dataspace profile.

The tab shows hardware counter memory operation metrics against the various data structures and variables in the program.

To select a single data object, click on that object.

To select several objects that are displayed contiguously in the tab, select the first object, then press Shift while clicking on the last object.

To select several objects that are not displayed contiguously in the tab, select the first object, then select the additional objects by pressing Ctrl while clicking on each object.

When you click the Compose Filter Clause button on the toolbar, the Filter dialog box opens with Advanced tab selected and the Filter clause text box loaded with a filter clause that reflects the selections in the DataObjects tab.

The DataLayout Tab

The DataLayout tab shows the annotated data object layouts for all program data objects with data-derived metric data. The layouts appear in the tab sorted by the data sort metrics values for the structure as a whole. The tab shows each aggregate data object with the total metrics attributed to it, followed by all of its elements in offset order. Each element, in turn, has its own metrics and an indicator of its size and location in 32–byte blocks.

The DataLayout tab can be displayed by selecting it in the Tabs tab of the Set Data Presentation dialog box (see Tabs Tab). As with the DataObjects tab, you can make the DataLayout tab visible only if one or more of the loaded experiments contains a dataspace profile.

To select a single data object, click on that object.

To select several objects that are displayed contiguously in the tab, select the first object, then press the Shift key while clicking on the last object.

To select several objects that are not displayed contiguously in the tab, select the first object, then select the additional objects by pressing the Ctrl key while clicking on each object.

When you click the Compose Filter Clause button on the toolbar, the Filter dialog box opens with Advanced tab selected and the Filter clause text box loaded with a filter clause that reflects the selections in the DataLayout tab.

The Inst-Freq Tab

The Inst-Freq, or instruction-frequency, tab shows a summary of the frequency with which each type of instruction was executed in a count-data experiment. The tab also shows data about the frequency of execution of load, store, and floating-point instructions. In addition, the tab includes information about annulled instructions and instructions in a branch delay slot.

The Statistics Tab

The Statistics tab shows totals for various system statistics summed over the selected experiments and samples. The totals are followed by the statistics for the selected samples of each experiment. For information on the statistics presented, see the getrusage(3C) and proc (4) man pages.

The Experiments Tab

The Experiments tab is divided into two panels. The top panel contains a tree that includes nodes for the load objects in all the loaded experiments, and for each experiment load. When you expand the Load Objects node, a list of all load objects is displayed with various messages about their processing. When you expand the node for an experiment, two areas are displayed: a Notes area and an Info area.

The Notes area displays the contents of any notes file in the experiment. You can edit the notes by typing directly in the Notes area. The Notes area includes its own toolbar with buttons for saving or discarding the notes and for undoing or redoing any edits since the last save.

The Info area contains information about the experiments collected and the load objects accessed by the collection target, including any error messages or warning messages generated during the processing of the experiment or the load objects.

The bottom panel lists error and warning messages from the Analyzer session.

The Index Tabs

Each Index tab shows the metric values from data attributed to various index objects, such as Threads, Cpus, and Seconds. Inclusive and Exclusive metrics are not shown, since Index objects are not hierarchical. Only a single metric of each type is shown.

Several Index tabs are predefined: Threads, Cpus, Samples, and Seconds. You can define a custom index object by clicking on the Add Custom Index Tab button in the Set Data Presentation dialog box to open the Add Index Objects dialog box. You can also define an index object with an indxobj_define directive in an .er.rc file (see indxobj_define indxobj_type index_exp).

A radio button at the top of each Index tab lets you select either a Text display or a Graphical display. The Text display is similar to the display in the DataObjects tab and uses the same metric settings. The Graphical display shows a graphical representation of the relative values for each index object, with a separate histogram for each metric sorted by the data sort metric.

When you click the Filter Data button on the toolbar, the Filter Data dialog box opens. Click the Advanced tab and the Filter clause text box loaded with a filter clause that reflects the selections in the IndexObjects tab.

The MemoryObjects Tabs

Each MemoryObjects tab shows the metric values for dataspace metrics attributed to the various memory objects such as pages. If one or more of the loaded experiments contains a dataspace profile, you can select the memory objects for which you want to display tabs in the Tabs tab of the Set Data Presentation dialog box. Any number of MemoryObjects tabs can be displayed.

Various MemoryObject tabs are predefined. You can define a custom memory object by clicking the Add Custom Object button in the Set Data Presentation dialog box to open the Add Memory Objects dialog box. You can also define a memory object with a mobj_define directive in an .er.rc file (see mobj_define mobj_type index_exp).

A radio button on each MemoryObjects tab lets you select either a Text display or a Graphical display. The Text display is similar to the display in the DataObjects tab and uses the same metric settings. The Graphical display shows a graphical representation of the relative values for each memory object, with a separate histogram for each metric sorted by the data sort metric.

When you click the Compose Filter Clause button on the toolbar, the Filter dialog box opens with Advanced tab selected and the Filter clause text box loaded with a filter clause that reflects the selections in the MemoryObjects tab.

Data Display, Right Pane

The right pane contains the MPI Timeline Controls tab, the MPI Chart Controls tab, the Summary tab, the Event tab, the Race Detail tab, Deadlock Detail tab, and Leak tab. By default the Summary tab is displayed.

The MPI Timeline Controls tab

The MPI Timeline Controls tab supports zoom, pan, event-step, and filtering for the MPI Timeline tab. It includes a control to adjust the percentage of MPI messages shown on MPI Timeline tab.

Filtering causes data outside the current field of view to be eliminated from the data set shown in the MPI Timeline tab and the MPI Chart tab. A filter is applied by clicking the Filter button. The back-filter button is used to undo the last filter; the forward-filter button is used to reapply a filter. Filters are shared between the MPI Timeline tab and the MPI Chart tab, but are not currently applied to other tabs.

The message slider can be adjusted to control the percentage of messages displayed. When you select less than 100%, priority is given to the most costly messages. Cost is defined as the time spent in the message's send and receive functions.

The MPI Timeline Controls tab is also used to show the details for a function or message selection from the MPI Timeline tab.

The MPI Chart Controls Tab

The MPI Chart Controls tab has a set of drop-down lists to control the type of chart, the parameters for the X and Y axes, and the Metric and Operator used to aggregate the data. Clicking Redraw causes a new graph to be drawn.

Filtering causes data outside the current field of view to be eliminated from the data set shown in the MPI Timeline tab and MPI Chart tab. A filter is applied by clicking the Filter button. The back-filter button is used to undo the last filter; the forward-filter button is used to reapply a filter.

The MPI Chart Controls tab is also used to show the details for a selection from the MPI Chart tab.

The Summary Tab

The Summary tab shows all the recorded metrics for the selected function or load object, both as values and percentages, and information on the selected function or load object. The Summary tab is updated whenever a new function or load object is selected in any tab.

The Event Tab

The Event tab shows detailed data for the event that is selected in the Timeline tab, including the event type, leaf function, LWP ID, thread ID, and CPU ID. Below the data panel the call stack is displayed with the color coding for each function in the stack. Clicking a function in the call stack makes it the selected function.

When a sample is selected in the Timeline tab, the Event tab shows the sample number, the start and end time of the sample, and the microstates with the amount of time spent in each microstate and the color coding.

The Leak Tab

The Leak tab shows detailed data for the selected leak or allocation in the Leaklist tab. Below the data panel, the Leak tab shows the call stack at the time when the selected leak or allocation was detected. Clicking a function in the call stack makes it the selected function.

The Race Detail Tab

The Race Detail tab shows detailed data for the selected datarace in the Races tab. See the Sun Studio 12: Thread Analyzer User’s Guide for more information.

The Deadlock Detail Tab

The Deadlock Detail tab shows detailed data for the selected Deadlock in the Deadlocks tab. See the Sun Studio 12: Thread Analyzer User’s Guide for more information.

Setting Data Presentation Options

You can control the presentation of data from the Set Data Presentation dialog box. To open this dialog box, click the Set Data Presentation button in the toolbar or choose View -> Set Data Presentation.

The Set Data Presentation dialog box has a tabbed pane with the following tabs:

The dialog box has a Save button with which you can store the current settings, including any custom-defined memory objects.


Note –

Since the defaults for the Analyzer, the er_print utility and the er_src utility are set by a common .er.rc file, output from the er_print utility and er_src utility is affected as a result of saving changes in the Set Data Preferences dialog box.


Metrics Tab

The Metrics tab shows all of the available metrics. Each metric has check boxes in one or more of the columns labeled Time, Value and %, depending on the type of metric. Alternatively, instead of setting individual metrics, you can set all metrics at once by selecting or deselecting the check boxes in the bottom row of the dialog box and then clicking on the Apply to all metrics button.

Sort Tab

The Sort tab shows the order of the metrics presented, and the choice of metric to sort by.

Source/Disassembly Tab

The Source/Disassembly tab presents a list of check boxes that you can use to select the information presented, as follows:

Formats Tab

The Formats tab presents a choice for the long form, short form, or mangled form of C++ function names and Java method names. If you select the Append SO name to Function name checkbox, the name of the shared object in which the function or method is located is appended to the function name or method name.

The Formats tab also presents a choice for View Mode of User, Expert, or Machine. The View Mode setting controls the processing of Java experiments and OpenMP experiments.

For Java experiments:

For OpenMP experiments:

For all other experiments, all three modes show the same data.

Timeline Tab

The Timeline tab presents choices for the types of event-specific data that are shown, the display of event-specific data for threads, LWP, or CPUs; the alignment of the call stack representation at the root or at the leaf; and the number of levels of the call stack that are displayed.

Search Path Tab

The Search Path tab allows you to manage a list of directories to be used for searching for source and object files. The special name $expts refers to the experiments loaded; all other names should be paths in the file system.

Pathmaps Tab

The Pathmaps tab enables you to map the leading part of a file path from one location to another. You specify a set of prefix pairs: the original prefix and a new prefix. The path is then mapped from the original prefix to the new prefix for a given path. Multiple pathmaps may be specified, and each will be tried in turn to find a file.

Tabs Tab

You can use the Tabs tab of the Set Data Presentation dialog box to select the tabs to be displayed in the Analyzer window.

The Tabs tab lists the applicable tabs for the current experiment. The standard tabs are listed in the left column. The Index tabs are listed in the center column, and the defined Memory tabs are listed in the right column.

In the left column, click the checkboxes to select or deselect standard tabs for display.

In the center column, click the check boxes to select or deselect Index tabs for display. The predefined Index tabs are Threads, Cpus, Samples, and Seconds. To add a tab for another index object, click the Add Custom Index Tab button to open the Add Index Object dialog. In the Object name text box, type the name of the new object. In the Formula text box, type an index expression to be used to map the recorded physical address or virtual address to the object index. For information on the rules for index expressions, see indxobj_define indxobj_type index_exp

In the right column, click the check boxes to select or deselect Memory Object tabs for display. To add a custom object, click the Add Custom Object button to open the Add Memory Object dialog box. In the Object name text box, type the name of the new custom memory object. In the Formula text box, type an index expression to be used to map the recorded physical address or virtual address to the object index. For information on the rules for index expressions, see mobj_define mobj_type index_exp

When you have added a custom index object or memory object, a checkbox for that object is added to the the Tabs tab and is selected by default.

Saving Data Presentation Options

The Set Data Presentation dialog box has a Save button to store the current settings.


Note –

Since the defaults for the Analyzer, the er_print utility and the er_src utility are set by a common .er.rc file, output from the er_print utility and the er_src utility is affected as a result of saving changes in the Analyzer’s Set Data Preferences dialog box.
