Synopsis

rtpm [ -h history_buffer_size] [ interval]

Description

The command rtpm displays operating system performance metrics and usage information in an interactive real-time curses-based graphical display.

The interval argument specifies the time in seconds between successive samples of the performance information. The default interval is two seconds.

The history_buffer_size argument specifies the number of history data points rtpm saves for plotting metrics. The default value for the history buffer size is the number of columns on the screen, as specified by the $COLUMNS environment variable.

Screen size

Using the IOCGWINSZ ioctl system call, rtpm attempts to automatically determine your screen size and adjust the display accordingly. However, if the $LINES and $COLUMNS environment variables are set, they take precedence over the ioctl call. In no case will the screen size be smaller than 24 rows by 80 columns.

Screen layout

The rtpm screen is divided into three areas. The top portion of the screen shows the graphical display, the bottom line of the screen displays the status of the monitor, and 14 lines between the graphical display area and the status line display text-based metric information.

The graphical display area contains a bar graph of CPU consumption, plots of metric data, or both. The text-based metric display area consists of numeric metric data, labels for the metric data, and subscreen headers. The numeric metric data, subscreen headers, and plot titles are cursor addressable.

Views

The metrics are available in either of two views: a CPU view and a CG view. In the CPU view, the metrics are displayed on a per-processor basis. In the CG view, the metrics are displayed on a per-CPU group basis, where each CPU group consists of a set of processors.

You can toggle between views using the <g> or <G> key. The default view is the CPU view.

Status line

The bottom line of the screen is the status display area. Typically, it contains the name of the machine, as returned by the uname(2) system call, the current date and time, the requested sampling interval, and the actual interval sampled. Two other messages may be displayed on the status line. The first is the message LOCKED that means rtpm has been locked in memory by the plock(2) system call; only privileged users are allowed to do this. The second message is Enter <?> for help.

Cursor motions

Move the cursor by pressing any of the following case-insensitive keys:

• the terminal arrow keys

• <H>, <J>, <K>, <L> (as in vi)

• <Ctrl><F>, <Ctrl><B>, <Ctrl><P>, <Ctrl><N> (as in emacs)

Plotting metrics

When the cursor is on a numeric metric data item, pressing either <Space> or the <Return> key causes the metric to be plotted in the graphical display area. The number of concurrent plots allowed depends on the size of the screen. A minimum of 7 rows and 40 columns in the graphical display area is required for a single plot. On a 24 row by 80 column screen, two concurrent plots can be displayed. Larger screens accommodate more plots.

When the cursor is placed on a plot (or bar graph) title, pressing either <Space> or the <Return> key removes the plot (or bargraph) from the graphical display area.

Pressing <C> clears whatever is in the upper-left corner of the graphical display area.

Scales for plots are determined by the maximum value contained in the history buffer at the time the plot is requested. If a later metric value is larger than the initial scale, the plot automatically re-scale to accommodate the larger value. Plots do not automatically re-scale to smaller values. Removing a plot and re-displaying it causes a new scale to be determined as above.

Displaying the bargraph

Use <B> to toggle on and off the display of the CPU consumption bar graph.

Changing the sampling interval

The sampling interval can be set by an argument at invocation. The default sampling interval is two seconds. The sampling interval may be changed at any time by pressing either <+> or <->, which increments or decrements the interval by one second. The minimum sampling interval is one second. Users should note that a one second sampling interval places a moderate load on the system, and is not particularly useful for identifying system problems.

Getting help

Press <?> to display the help screen in the text portion of the screen. Press <Esc> to return to the previous screen.

Quitting rtpm

Press <Q> or <Ctrl><D> to exit rtpm.

Accessing subscreens

Press <Space> or <Return> while the cursor is on a subscreen header to change the text-based metric display to the subscreen. Press <Esc> to return to the previous screen. Twelve subscreens are available from the top level screen:

In the default startup display, a bar graph of CPU utilization is displayed in the graphical portion of the screen. When rtpm is run on a multi-processor system, there is a bargraph for each CPU on the system and one for total CPU consumption. Systems with more than four processors require a screen size that contains more than 24 rows to display the entire bar graph. When rtpm is run on a small screen and is displaying statistics for a large multi-processor configuration, not all CPUs are displayed in the bar graph. A scroll bar at the left of the bar graph shows whether the bar graph can be scrolled up or down. The bar graph may be scrolled up and down with the <^> and <V> keys. In the CG view, the bar graph is displayed for CG-based CPU usage.

Pressing the <I> key when the CPU bargraph is displayed reports the percentage time spent processing interrupts; pressing <I> again turns off the display of interrupt data. Time spent in interrupt handling is represented by the <+> character as shown in the following display.

 CPU 0  ====================================================++++++-------------
 CPU 1  ===-------
 CPU 2  -
 CPU 3  -

If the bargraph is cleared and the percentage cpu (usr+sys+int) time metric is plotted, the display looks like this:

By default, the LWP subscreen displays all processes that have been active during the sampling period. Pressing <U> or <S> while the LWP subscreen is displayed limits the data to user or system processes, respectively. Pressing the <A> key reports all active user and system processes. The <e> key acts as a toggle switch: pressing <E> once displays all processes, including sleeping processes; pressing <E> again causes only active processes to be displayed. The keys can be used in combinations: pressing <A> and <E> will show all of the processes (including sleeping processes) that are on the system, pressing <U> and <E> will show all of the user processes, and pressing <S> and <E> will show all of the system processes. If more processes run during the sampling interval than will fit on the screen, the <<> and <>> keys can be used to scroll through the list.

In the CG view, an extra column is added to the PS output to display the CG on which a lwp is executing.

On systems with a large number of CPUs, disks, or ethernet cards, the per-unit metrics associated with these resources may not fit on a small screen. When this happens, <-, ->, or <> will be displayed at the right edge of the screen and the <<> and <>> keys can be used to scroll the per-resource metrics left and right. Moving the cursor off the edge of the screen also scrolls per-resource metrics.

Command summary

Cursor Motions

The arrow keys, <H>, <J>, <K>, <L>, and <Ctrl><B>, <Ctrl><N>, <Ctrl><P>, <Ctrl><F> move the cursor left, down, up, and right, respectively.

Changing Views

You can toggle between the CPU and CG views using the <g> or <G> key. The default view is the CPU view.

Plotting Metrics

Press <Space> or the <Return> key while the cursor is on a numeric metric to plot the metric. Enter <P> to change the plotting format. Press the <Space> bar or the <Return> key while the cursor is on a plot title to delete the plot. Pressing <C> deletes the plot (or bar graph) in the upper left corner of the screen.

Accessing Subscreens

Press <Space> or the <Return> key while the cursor is on a subscreen header to display the subscreen associated with the header. Press <Esc> to return to the previous screen.

Locking rtpm into Memory

Privileged users can use <X> as a toggle to lock or unlock rtpm in memory.

Bargraph

Press <B> to toggle on and off the display of the percentage CPU consumption bar graph. On multi-processing systems that cannot fit information about all their processors/CGs within the available display area, the <^> and <V> keys scroll the bar graph up and down.

Changing the Sampling Interval

The <+> and <-> keys increment and decrement the sampling interval.

Scrolling Metrics

When the text display area is not large enough to display all per-resource metrics, scroll the display using the cursor keys or the <<> and <>> keys.

LWP Screen

Scroll the LWP screen that displays the ps data using the <<> and <>> keys. The ps report can be limited to user or system, or to show all processes by the <U>, <S>, and <A> keys, respectively.

Underscore Handling

Some termcap entries do not handle the terminal underscore capability correctly. Use the <_> key to toggle between selecting whether rtpm tries to use the underscore attribute or draws an ASCII underscore character.

Redraw

Enter <Ctrl><L> to redraw the screen.

Exiting rtpm

Enter <Q> or <Ctrl><D> to exit rtpm.

Initialization file

When rtpm is invoked, it attempts to read the .rtpmrc initialization file from the user's home directory. If the .rtpmrc file is not found in the user's home directory, the system default /etc/.rtpmrc is used.

The native language in which the .rtpmrc file is written is specified by the expression LANG=language, where language is a locale name describing the message catalog to be used for reading the initialization file. For example, setting LANG=C specifies the default English language strings as used in /etc/.rtpmrc. Note that setting LANG in the .rtpmrc file does not affect the messages displayed by rtpm.

The initialization file can be used to specify a default set of metrics to plot at initialization time, and also specifies the display colors for color terminals. Each line of the initialization file consists of a name, a colon, and an expression that specifies color or default plotting status.

The following display elements are specified in the initialization file:

background

the background color.

default

the default numeric metric display color.

plot

the default plotting color.

labels

the display color for metric and plot labels.

headers

the display color for cursor addressable subscreen headers and plot titles.

messages

the display color for informational and error messages.

bargraph

the display color range for the %CPU bar graph.

metric names

the display color ranges and plotting status for individual metrics.

Each of the above display elements may be assigned one of the following colors: magenta, red, yellow, green, cyan, blue, black, and white. The bargraph and metrics can be assigned a color range expression, and metrics can be assigned a plotting status.

Color range expressions are used to assign display colors to ranges of metric values. A color range expression consists of a series of numbers, relational operators, and colors:

   <color_range>::
   <RANGE>[;<RANGE>]
   <RANGE>::
   	[<num><OP>]<color>[<OP><num><OP><color>]*[<OP><num>]
   <OP>::
   	< | <= | > | >= | == | !=

For example

   bargraph: 0 <= green < 60 <= yellow < 85 <= red

sets the bargraph to green if CPU consumption is below 60%, yellow if it is between 60% and 85%, and red if it is greater than 85%.

Multiple expressions may be used, provided they are separated by semicolons. Since expressions are tested from left to right, the following expression is equivalent to the one above:

   bargraph: green < 60 ; yellow < 85 ; red

In the text-based metric display area, the color assigned to default is used to display the numeric metric unless a color expression specifies otherwise. In the plot area, the color assigned to plot is used to display the plot characters unless a color expression specifies otherwise. In both the text-based and graphical display areas, if a color expression is true, the metric will be displayed in the color defined by the expression. Typically, colors will vary from green to yellow to red depending on the severity of a condition. On vertical bar chart plots, this will have the effect of several color bands, one above the other.

For metrics that indicate an alarm condition when they approach 0, such as free memory, the user may want to invert the plot so that 0 is displayed as the top of the y-axis as opposed to the bottom. Thus the plot will only display the alarm color under severe conditions.

To invert a plot, add the invert keyword to a metric in the initialization file:

   freemem: 1000 >= yellow > 500 >= red ; invert

Plot status expressions are used to specify metrics that are to be plotted when rtpm is invoked. Since metrics can be per-resource based, a metric is actually a set of values called instances. A metric has an instance for each resource (or combination of resources) on which it is based. For example, freemem is global, %usr time is kept per-CPU, and igets/s are kept both per-CPU and per-filesystem. Hence, there is one instance for freemem, n CPU instances for %usr, and n CPU * nfstyp instances for igets/s. A plot expression is used to specify the set of instances the user wants to plot. Here are some examples of plot expressions:

plot

plot a single global metric or the total of a resource based metric.

plot(total)

plot the total of a metric that has one resource.

plot( number )

plot the instance associated with resource number such as plot(2)) to plot the value associated with CPU #2.

plot(*)

plot all the instances associated with this single dimensional metric.

plot(2, 3)

plot the instance associated with the first resource of 2 and the second resource of 3, such as igets/s for CPU #2 and filesys #3.

Multiple plot expressions are separated by semi-colons. If there is not enough room on the screen for the requested plots, the ones specified last in the initialization file are displayed, and no error message is generated.

Usage note

On heavily loaded systems where memory is scarce, and especially with large screen sizes, rtpm may fail to allocate enough space to save all its history points. If this is the case, the history buffer size should be decreased using the -h option. On systems with ample memory, large display screens may benefit from increasing the history buffer size to the number of columns on the screen.
