     TECHNICAL FIELD  
       [0002]     The present system is in the field of systems and articles of manufacture to administer and analyze complex, heterogeneous networked computer systems and other systems that can be monitored by computer technology. More specifically, the present system is directed to systems and articles for enabling user selection and presentation of a property of an object in a three dimensional graphic display.  
       BACKGROUND  
       [0003]     In known system management applications, the visualization of the contents, configuration, and state of the managed system is usually based on some form of display, ranging from a list of items, to icons arrayed in some meaningful way, to 2-D diagrams, to 3-D views. The type of each object may be indicated with an icon of some sort, while the identity and/or state of the object is often rendered in text form. Variations on these themes exist, such as displays that are completely textual and those that use no text at all, but common to all such systems is a core display that shows the objects under management and their relationships.  
         [0004]     Using 3-D visualization to render objects conveys a more realistic view of managed objects and their configuration. However, one problem with such a technique is that system management applications typically only show 3-D images of the basic description of the objects, such as their type and inter-connectivity. Another problem is that common system management applications only show fixed properties of the managed objects.  
         [0005]     To show the general state of the managed objects, which may include values of their properties, such as state, load, error rate, integrity, and available capacity, known systems typically use some form of visualization appropriate to the metrics of interest. For example, to show the status of the object, an indicator of its essential health, ranging from NORMAL to CRITICAL and also taking on values such as UNKNOWN, it is common to use color, where green might indicate NORMAL, red might indicate CRITICAL and gray or black indicate UNKNOWN.  
         [0006]     In real-world displays, it is not practical to surface all the information about the managed object in this core 3-D display. Although some applications have attempted to do this by displaying textual information on planes in 3-D, such displays are harder to read than plain 2-D text because of the limited resolution of current equipment and because current systems do not have enough computational power to anti-alias text or other graphical elements in real time. If this much information is desired, using a 2-D visualization model is considered superior. The benefits of 3-D views appear to be best gained by employing 3-D metaphors.  
         [0007]     Some systems generate 3-D bar charts, usually standing on a plane in a regular grid. However, these bar charts have many problems. Most notably, the bars appear to be standing on a totally abstract floor plane, not one that represents the real-world objects interconnected through network links. In addition, such general charting systems are based on collected statistics, and not on real-time monitoring measurements coming out of a management system.  
         [0008]     In order to show the other very important and detailed information about the managed objects in a practical way, it is commonplace to provide some mechanism for “drilling down,” thereby retrieving more detailed information about the object from an information store, using a conventional user interface. For example, in network and systems management systems, it is common to surface status in the core display but provide performance and load indicators in other displays that may be brought up from the core display.  
         [0009]     Unfortunately, these arrangements have some disadvantages. When additional information is brought up in secondary displays, the secondary displays deviate from the normal navigation conventions of the core 3-D display. In this situation, to see the secondary data on various management objects, it is necessary to first navigate to them, then bring up the secondary display, then navigate to other objects and bring up their secondary displays. Using such an interface is not only cumbersome, but it also impedes a user&#39;s ability to compare properties of several objects at once.  
         [0010]     In addition, fixed arrangements of this type may not suit every user. For example, while many users may be primarily interested in status and consider load secondary, the person in charge of managing load balancing across the network may be more interested in instantaneous load displays.  
         [0011]     Some system management applications provide for customizing the display in two areas. The information displayed in conjunction with the icon in typical displays may be selected from the properties of the objects, so that the icon shows various pieces of information in the form of text, color or other ways. Alternatively, moving the mouse cursor over a symbol in the display may bring up a configurable reticule with labeling, again displaying different properties. This customization is often done specific to each class of object, so different information is displayed about a server and a router, for example. However, this type of configuration is typically static, requiring the user to enter some sort of configuration utility. No known system provides a real time configuration of the display.  
       SUMMARY  
       [0012]     In accordance with the disclosed system, a first method for presenting a status of an object in a three dimensional graphic display is disclosed. The method includes the step of determining a value of a property associated with an object. The method further includes the step of determining a status indicator associated with the property. A status indicator is then generated representing the property associated with the object, and displayed relative to the associated object.  
         [0013]     In accordance with the disclosed system, a second method for presenting a user selected status of an object in a three dimensional graphic display is disclosed. The method includes the steps of receiving a request to select a property of an object for display and displaying at least one property which may be displayed for the object. The method further includes the step of receiving a selection of a property. The value of the selected property for the object is determined and a status indicator is generated based on the value of the selected property. The status indicator is then displayed relative to the object.

     DETAILED DESCRIPTION  
       [0022]     The various components that comprise a preferred embodiment of the disclosed network analysis system are shown in  FIG. 1 . The system includes one or more of a visualization workstation  101 , an object repository  102 , one or more management applications  103 , and one or more agents  104  on each such management application. The visualization workstation  101  interacts primarily with the object repository  102 . It requests information from it, it sends commands to it, and it gets notification of events such as status change or object additions from it. The repository  102  in turn gets this information form the various management subsystems  103 , which are fed by agents  104  on the managed systems. An important architectural consideration of the present system is that in normal operation, the visualization workstation  101  preferably interacts with the object repository  102 . This minimizes network traffic, optimizes the performance of the rendering of the workstation, and minimizes the interconnectivity between the visualization workstation  101  and the multitude of management subsystems and agents existing in practical networks.  
         [0023]     Preferably, the management system is based on some type of store, preferably the object repository  102 , that holds the description of the structure of the network. This can include the momentary state, load, and performance of the network and the systems. This store may or may not be persistent, it may be populated with a manual process, or with an automatic discovery utility.  
         [0024]     According to a preferred embodiment of the present system, as shown in  FIG. 2 , a management system outputs a display  202  of the managed objects using 3-D models  204  of real-world objects, configured in suitable positions over 3-D sections  208  of a 3-D surface, and interconnected with at least one line  206  that shows a network link, where optional links are shown as dots and dashed lines. The status of each object  204  is indicated with a hovering light  212 , whose color indicates status from green through yellow, orange and red. The status of network link  206  may be indicated by coloring the link itself.  
         [0025]     Turning to  FIG. 3 , a more detailed view of the display  202  in  FIG. 2  is shown. As seen in  FIG. 3 , according to a preferred embodiment of the present system the system generates additional objects  302 , such as a vertical bar, next to each representation  204  of a “real-world” object. The present system uses these additional objects  302  to indicate in real time quantitative or qualitative measures of the managed objects.  
         [0026]     As seen in  FIG. 4 , an alternative preferred embodiment includes an indicator section  302  that displays other indicators in the core display  202 . In this and other alternative preferred embodiments of the disclosed system, the indicator section  302  can include color, animation effects, icon choice, text, bar, line or pie charts near the managed object, and others. The managed objects  204  have a set of properties, some numeric, some textual, and some categorical. Current system management applications support surfacing some fixed set of properties in the core display using fixed indicators, but other properties must be brought up through an explicit request, after which they are visualized using a technique determined by the application.  
         [0027]     To overcome these problems, the preferred embodiment of the disclosed system provides an interface  304 , preferably a property selection control panel, that permits a user to select properties the user desires to monitor in the indicator section  302  using predetermined indicators. In other embodiments, the user may select a type of indicator to be used from a menu of indicators, such as for example bar graph, indicator light and pie chart.  
         [0028]     A user can interact with interface  304  by point-and-click operations after placing a cursor  306  over a box  308 , or any similar configuration or arrangement, in the interface  304 . After clicking on the box  308 , the area chosen by the user is correlated to a predetermined property to be displayed X n  through X n+m    310 , where n and m are integers. In use, X n  through X n+m  are textual representations of the available properties. Thus, in the preferred embodiment of the disclosed system, the indicators  310  are the actual textual names of the properties chosen. Preferably, all properties, are visualized in a standard way after being explicitly requested, so there is no need for customization of the secondary displays.  
         [0029]     In the preferred embodiment, after a user interacts with the control panel  304 , there is an immediate effect to the indicator section  302  in the display  202 , without requiring any complex settings in a dialog box, a confirmation dialog, or even pressing an OK button, which would break the flow of the operation and distract the user from the information displayed.  
         [0030]     Further, the property selection control panel  304  preferably acts as an indicator of what information is currently displayed. In the preferred embodiment, distinct indicators for the various types of information are used through bars  312 , preferably a yellow-orange-red color range indicates status and shades of blue indicate load. In this way, a knowledgeable user can immediately tell, by looking at the control panel  304  in the display  202 , what information is currently displayed. In the preferred embodiment, the control panel  304  shows the current indicators, such as colors or animation effects, as well as the corresponding property, identified by name. Providing both a textual description of the properties and their corresponding visual displays in control panel  304  assists a novice user who may know the meanings of the various visual displays employed by the system.  
         [0031]     For example, as seen in  FIG. 5 , to indicate the real time percentage load of a computer system, the additional object  302   a  can be a solid bar  304  that reaches up to a corresponding percentage within an empty, transparent bar. In some ways, this resembles a conventional bar chart, with the percentage scale  306  on an x axis above the bar  304 , but combined with a 3-D display  202  of real-world objects that are arranged in a way that represents the real-world configuration of these managed objects.  
         [0032]     According to a preferred embodiment of the present system, indicator  302  is made translucent. This avoids making the visualization  302  unreadable due to the large number of objects  204  and their quantitative indicators  302 , such as the bars  304 . The effect is that of “colored water” reaching up to a certain level in a “glass aquarium tank.” The colored area that represents the actual traffic load or performance is colored fairly solidly, just translucent enough to indicate the distinction between this quantitative measure and the real-world objects, and to prevent the quantitative measures from obstructing the view of other objects. The empty part of the tank, representing capacity of the system that is currently not exploited, is almost entirely transparent, rendered just opaque enough to give an impression of a glass tank.  
         [0033]     In addition, in alternative preferred embodiments of the present system, the system uses other advanced visualization techniques, such as reflections in the “glass surfaces” and the “edges of the glass tank” to increase the perceived realism and reduce the visual clutter between the managed objects  204  and the quantitative indicators  302 .  
         [0034]     In  FIG. 6 , a preferred method  600  is shown. The method starts at  602 , after which a request is received to select a property of an object to be displayed at  604 . This request is preferably initiated by a user indicating that the user wishes to customize the display, for example by double-clicking on an object or by right-clicking on an object and making a menu selection.  
         [0035]     At step  606 , the property selection control panel is displayed. The control panel contains at least one property which may be selected for display. A selection of a property from the control panel is received at step  608 . The value of the selected property for the object is determined at  610 . This determination is preferably performed in real-time with reference to data contained in object repository  102 . A status indicator is generated based on the determined value of the selected property at step  612 , and the status indicator is displayed at step  614 .  
         [0036]     Accordingly, it is to be understood that the drawings and description in this disclosure are proffered to facilitate comprehension of the system, and should not be construed to limit the scope thereof It should be understood that various changes, substitutions and alterations can be made without departing from the spirit and scope of the system.
