pmview - performance metrics 3D visualization back-end
pmview [-Cz] [-A align] [-a archive[,archive,...]] [-c
configfile] [-h host] [-n pmnsfile] [-O origin] [-p port] [-R
logconfig] [-r addconfig] [-S starttime] [-t interval] [-T

"resourceName: value" ...] [other X11-args]
pmview is a generalized 3D performance metrics visualization tool
for the Performance Co-Pilot (PCP(1)).
pmview is the base utility behind performance metrics
visualization tools such as dkvis(1), mpvis(1), osvis(1) and
nfsvis(1), It is also used by a range of related tools that are
specific to optional Performance Domain Agents (PMDA) and/or PCP
add-on products. pmview may also be used to construct customized
3D performance displays.
pmview displays performance metrics as colored blocks and
cylinders arranged on monochrome base planes. Each object may
represent a single performance metric, or a stack of several
performance metrics. Since the objects are modulated by the
value of the metric they represent, only numerical metrics may be
visualized. Objects representing a single metric may be
modulated in terms of height, color, or height and color.
Objects in a stack may only be height modulated, but the stack
can be normalized to the maximum height. Labels may be added to
the scene to help identify groups of metrics.
A configuration file (as specified by the -c option, or read from
standard input) is used to specify the position, color, maximum
value and labels of metrics and metric instances in the scene.
The maximum value acts as a normalization factor and is used to
scale the object height and/or color in proportion to the metric
values. Metric values which exceed the associated maximum value
are displayed as solid white objects. If a metric is
unavailable, the object will have minimum height and will be
colored grey.
Normally, the tool operates in ``live'' mode where performance
metrics are fetched in real-time. The user can view metrics from
any host running pmcd(1). pmview can also replay archives of
performance metrics (see pmlogger(1)) and allow the user to
interactively control the current replay time and rate using the
VCR paradigm. This is particularly useful for retrospective
comparisons and for postmortem analysis of performance problems
where a remote system is not accessible or a performance analyst
is not available on-site.
All metrics in the Performance Metrics Name Space (PMNS) with
numeric value semantics from any number of hosts or archives may
be visualized. pmview examines the semantics of the metrics and
where sensible, converts metric values to a rate before scaling.
The -S, -T, -O and -A options may be used to define a time window
to restrict the samples retrieved, set an initial origin within
the time window, or specify a ``natural'' alignment of the sample
times; refer to PCPIntro(1) for a complete description of these
options.
The other available options are:
-a archive[,archive,...]]
Specify an archive from which metrics can be obtained for
a particular host. archive is the basename of an archive,
or the name of a directory containing archives, previously
created by pmlogger(1). Multiple sets of archives
(separated by commas or in different -a options) from
different hosts may be given, but an error will occur if
there is more than one set of archives from the same host.
Any metrics that are not associated with a specific host
or archive in the configuration file will use the first
set of archives as their source.
-C Parse the configuration file and exit before displaying
the pmview window. Any errors in the configuration file
are displayed.
-c configfile
Load the configuration from configfile rather than
standard input.
-h host
Fetch performance metrics from pmcd(1) on host, rather
than the default localhost. Implies that pmview will run
in live mode, so no archives can be specified on the
command line or in the configuration file. Only one -h
option may be given.
-n pmnsfile
Normally pmview operates on the distributed Performance
Metrics Name Space (PMNS), however if the -n option is
specified an alternative local PMNS is loaded from the
file pmnsfile.
-p port
Connect to the time controls (see pmtime(1)) on this port.
Used when a tool launches another tool so that they can
connect to the same time controls.
-R logconfig
Use logconfig as the pmlogger(1) config when recording.
-r addconfig
Append addconfig onto the pmlogger(1) config generated by
pmview when recording.
-t interval
The update interval used to fetch metrics from the live or
archive sources. The interval argument follows the syntax
described in PCPIntro(1), and in the simplest form may be
an unsigned integer (the implied units in this case are
seconds). The default is 2.0 seconds.
-x version
Use the specified version of the pmlaunch(5)
specification. The versions currently supported are
``1.0'' and the default version ``2.0''.
-Z timezone
By default, pmview reports the time of day according to
the local timezone on the system where pmview is run. The
-Z option changes the default timezone to timezone which
should be in the format of the environment variable TZ as
described in environ(7).
-z Change the reporting timezone to the local timezone at the
host that is the source of the performance metrics, as
identified via either the -h option, or the first -a
option.
-geometry geometry
-display display
-name name
-title title
-xrm "resourceName: value"
Most standard X(1) command line arguments may be used.
The pmview window is comprised of a menu bar, time and scale
controls, metric and time values, and an ``examiner'' viewer (see
ivview(1)), which displays the 3D scene.
The left, right and bottom edges of the examiner viewer contain a
variety of thumb wheels and buttons that can be used to adjust
the visualization of the 3D scene. The Rotx and Roty thumb
wheels allow the user to rotate the scene about the x and y axes,
respectively. The dolly thumb wheel moves the virtual camera
closer and further from the scene allowing the user to examine
specific parts in detail or view the entire scene. On the right
edge of the viewer are eight buttons which affect the way the
user can interact with the scene.
Pointer
Changes the cursor to a pointer which allows blocks to be
selected in the scene. See the Metric Selection section
below.
Hand
Changes the cursor to a hand which allows the scene to be
rotated, translated and dollied using a combination of mouse
buttons. The left mouse button can be used to rotate the
scene in the direction of the mouse. Releasing the left
mouse button before the mouse has stopped moving will cause
the scene to continue to rotate, which can be stopped by
pressing the left mouse button again. The middle mouse
button will ``pan'' the scene, and both mouse buttons act as
a dolly for the virtual camera.
Question Mark
Displays the SGI Help information for the examiner viewer.
Home
Changes the scene back to its original position, unless the
home position has been changed by the home pointer button.
Home Pointer
Changes the home position of the scene to be the scene
currently in view.
Eye Resizes the scene so that it completely fits into the 3D
viewing area.
Cross-hairs
Moves the object under the cursor to the center of the
viewing area, if the hand cursor has been selected. Pressing
the ``s'' key while the cursor is over an object has the same
effect.
Perspective Box
Switches the display between perspective and orthogonal
projections.
Pressing the right mouse button within the scene window will
bring up a menu of options which affect how the 3D scene is
drawn. The options include drawing the blocks as wire frames,
and turning on stereo viewing.
When the pointer cursor is active, more information about the 3D
scene can be obtained. Text describing the metric represented by
the block under the cursor will be displayed in the top text box
of the pmview window. The text contains the source and name of
the metric, current value and units, and the percentage of the
expected maximum (or normalization) value. The text box is
updated whenever the scene is updated with the latest metric
values or when the cursor is moved over another block in the
scene. Moving the cursor over a base plane block, text or the
surrounding space will clear the text box.
Clicking the left mouse button on a block will bind the text box
on that metric instance so that the metric can be monitored while
performing other actions with the mouse. The block will be
highlighted with a red wire frame. Clicking the left mouse
button on text or the space surrounding the scene will unselect
the object, causing the text box to revert to the original
behavior of showing the metric underneath the cursor.
Selecting a base plane instead of a modulated block will cause
all the blocks on that base plane to be selected. When more than
one object is selected, the text box behaves as if nothing is
selected, so the metric displayed is the metric currently under
the cursor. Multiple selections are also possible by pressing
the SHIFT key while selecting an object with the left mouse
button.
There are four menus in pmview's user interface which allow
scenes to be recorded, saved and printed (File), access to the
time controls (Options), launching other tools (Launch) and
online help (Help).
File/Record
When in ``live'' mode, this option will launch pmlogger(1)
processes to record the current scene into an archive folio
(see pmafm(1)) so that it may be replayed at a later time.
This option is not available in ``replay'' mode.
When File/Record is selected, a file chooser dialog will
prompt for the name of the new archive folio. If the
directory to the folio does not exist, pmview will attempt to
create it. It is usually convenient to keep each folio
within its own directory as there will be several other files
associated with the folio, including the generated archives.
Once a valid folio has been created, pmview will launch a
pmlogger(1) process for each host to collect the metrics
required from that host in the current scene. The current
selections do not affect the set of metrics that are
recorded.
While recording is in progress, a red dot will appear in the
time controls button in the top left-hand corner of the
pmview window. The File/Record option will also change to
File/Stop Recording as only one recording session is possible
at any one time. Selecting blocks or launching other tools
will have no affect on the recording session.
The record session may be terminated by selecting File/Stop
Recording. This will display dialogs for each pmlogger(1)
instance describing the size and location of the archive
files before terminating each process. When all pmlogger(1)
processes have been terminated, the red dot is removed from
the time controls button, and the menu reverts back to
File/Record to allow another recording session to take place.
If the application exists while recording, a dialog will
appear allowing you to terminate each pmlogger(1) process, or
leave it running unattached.
An archive folio may be replayed using the command: ``pmafm
folio replay''. See pmafm(1) for more details.
It is not uncommon for a front-end script which generates a
pmview scene to use metrics that are not contained in the
scene. For example, osvis(1) uses several hinv metrics to
determine the size and layout of some objects. As these
metrics are also needed when replaying the generated archive
with the front-end script, a complete pmlogger(1) config can
be specified (-R) that overrides the pmview generated config,
or an additional config can be appended (-r) to the pmview
generated config.
File/Save
Saves the current scene to a human-readable Open Inventor
file (see inventor(1)). A file dialog will prompt for the
location of the file. The default file extension is ``.iv''
which is recognized by ivview(1) and some Web browsers.
File/Print
Outputs the current scene to a printer. A print dialog will
be displayed allowing a specific printer to be selected.
File/Quit
pmview immediately exits. If recording was active, dialogs
will be displayed for each pmlogger(1) process so that they
may be terminated.
Options/Show Time Control
Displays the time controls (see pmtime(1)) that are driving
this instance of pmview. The time controls may be shared by
other tools, including pmchart(1), that have been launched by
other instances of pmview and oview(1). Therefore, this menu
item may appear to have no affect if the time controls are
already visible.
Options/New Time Control
Disconnect with the current time controls (which may be
shared by other tools, see pmtime(1)) and use a new time
control that is not connected to any other tools. The new
time control will be immediately displayed.
Launch
The launch menu is generated from a menu specification file
(see pmlaunch(5)). The menu contains tools that may be
launched based on the sources and names of the selected
metrics in the scene. For example, if the selected metrics
are from three different hosts, then three copies of a tool
may be launched, one for each host. The behavior of a launch
depends on the selected metrics and the tools being launched.
On selection of a Launch menu item pmview generates state
information in the pmlaunch(5) metrics specification format.
This provides a description of the selected metrics (or if
there are no selections, all the metrics) in the scene
without any geometry information.
Tools which can monitor multiple hosts and user specified
metrics may be launched only once for those metrics (eg
pmdumptext(1)). Other tools which have a fixed view for one
host (eg mpvis(1)), may be launched multiple times, once for
each host in the selected metric list. If the launched tools
have time controls, they will share the time controls with
the launching pmview.
The set of launched tools is configurable, and may include
IRIX and user applications. See pmlaunch(5) for more
details.
Help/...
If pcp.books.help has been installed, then the insight(1)
books for pmview are displayed.
In addition to the menu options for time controls, the current
direction of the time controls (see pmtime(1)) is shown in a
button in the top-left corner of the pmview window. Pressing
this button will display the time control and is identical in
behavior to Options/Show Time Control.
Above the examiner window is a thumb wheel and an editable text
box which allow the user to apply a multiplier to all values
represented in the scene. Spinning the wheel to the right and/or
increasing the text value for the scale will increase the height
of the bars. Spinning the wheel to the left and/or lowering the
text value will decrease the height of the bars. The button to
the right of the thumb wheel will reset the scale so that the
bars appear at the original height for their current value.
Beside the scale controls is another text box which displays the
time of the fetched metrics. The time will change with the time
controller (see pmtime(1)).
Are intended to be self-explanatory. The environment variable
PCP_STDERR can be set to force most startup warnings and errors
to be sent to the standard error stream rather than posted in a
dialog.

Environment variables with the prefix PCP_ are used to
parameterize the file and directory names used by PCP. On each
installation, the file /etc/pcp.conf contains the local values
for these variables. The $PCP_CONF variable may be used to
specify an alternative configuration file, as described in
pcp.conf(5).
