     DETAILED DESCRIPTION 
       [0009]    Embodiments of the present invention will now be described in detail with reference to the accompanying Figures. 
         [0010]      FIG. 1  illustrates display system  100 , in accordance with an embodiment of the invention. In an exemplary embodiment, display system  100  includes server  110 , computing device  120 , and computing device  140  all interconnected via network  130 . 
         [0011]    In the exemplary embodiment, network  130  is the Internet, representing a worldwide collection of networks and gateways to support communications between devices connected to the Internet. Network  130  may include, for example, wired, wireless or fiber optic connections. In other embodiments, network  130  may be implemented as an intranet, a local area network (LAN), or a wide area network (WAN). In general, network  130  can be any combination of connections and protocols that will support communications between server  110 , computing device  120 , and computing device  140 . 
         [0012]    Computing device  120  may be a desktop computer, a notebook, a laptop computer, a tablet computer, a handheld device, a smart-phone, a thin client, or any other electronic device or computing system capable of receiving and sending data to and from other computing devices, such as computing device  140  and server  110 , via a network, such as network  130 . Although not shown, optionally, computing device  120  can comprise a cluster of web devices executing the same software to collectively process requests. 
         [0013]    Computing device  140  may be a desktop computer, a notebook, a laptop computer, a tablet computer, a handheld device, a smart-phone, a thin client, or any other electronic device or computing system capable of receiving and sending data to and from other computing devices, such as computing device  120  and server  110 , via a network, such as network  130 . Although not shown, optionally, computing device  140  can comprise a cluster of web devices executing the same software to collectively process requests. 
         [0014]    Server  110  includes display program  112 . Server  110  may be a desktop computer, a notebook, a laptop computer, a tablet computer, a handheld device, a smart-phone, a thin client, or any other electronic device or computing system capable of receiving and sending data to and from other computing devices, such as computing device  120  and computing device  140 , via a network, such as network  130 . Although not shown, optionally, server  110  can comprise a cluster of web devices executing the same software to collectively process requests. Server  110  is described in more detail with reference to  FIG. 3 . 
         [0015]    In the example embodiment, display program  112  is a program capable of receiving information (historical information and current information) from computing devices, such as computing device  120  and computing device  140 , detailing usage information, information regarding attributes of the device(s), and/or information detailing other aspects of the device(s). Furthermore, display program  112  is capable of normalizing the received information/data and displaying the normalized data graphically in order for outlier data points receives from each computing device to be identified. In addition, display program  112  is capable of receiving user input via a user interface from the user of server  110 . The operations and functions of display program  112  are described in more detail with reference to  FIG. 2 . 
         [0016]      FIG. 2  is a flowchart illustrating the operations of display program  112  in normalizing data and displaying the normalized data graphically in order to identify outliers, in accordance with an embodiment of the invention. In the example embodiment, display program  112  receives historical data from one or more computing devices, such as computing device  120  and computing device  140  (step  202 ). In the example embodiment, display program  112  receives information detailing usage statistics and capacity constraints of computing device  120 , computing device  140 , and also attributes of each device. For example, display program  112  may receive information detailing historical usage of a processor of computing device  120 , the capacity/capabilities of the processor, and also usage and capacity information regarding memory/storage devices present on computing device  120  (attribute of computing device  120 ). In addition, the historical data may have been time-stamped so that display program  112  is able to determine the period of time the data corresponds to. 
         [0017]    Display program  112  normalizes the historical data (step  204 ). In the example embodiment, display program  112  normalizes the historical data and also determines a normal range for the historical data (a historical norm for the data set). In the example embodiment, normalizing the historical data allows data that may pertain to different devices to be viewed in a common scale. For example, computing device  120  may have a processor having a higher speed and higher capabilities than computing device  140 , therefore normalizing the data coming from the computing devices and depicting the data on a common scale allows a user to view usage statistics on a common scale for device and attributes of varying capabilities. In another example, computing device  120  and computing device  140  may have similar or the same processor speeds and capabilities, however, computing device  140  may be a failover device for computing device  120 , and therefore, computing device  140  may have a usage statistics that are lower than computing device  120  (due to computing device  140  being idle at times waiting for failover). In this example, normalizing the historical data for each device still allows the data (usage statistics) to be viewed on a common scale. 
         [0018]    In the example embodiment, display program  112  determines a normal range through standard deviation calculations. In the example embodiment, display program  112 , normalizes the historical data, determines an average of the normalized data, and then determines a standard deviation of the normalized data set with respect to the historical average in order to determine a normal range. For example, if the historical data set is normalized with the normalized data set including 40, 40, 40, 45, 50, and 55, display program  112  determines the average of the normalized data set to be 45. Display program then determines the standard deviation for the data set, which is approximately 5.77. In the example embodiment, the normal range is defined as two standard deviations from the historical average. Therefore, the normal range is 11.54 above and below 45. In other embodiments, the normal range may be defined as a different number of standard deviations from the historical average. 
         [0019]    In another embodiment, display program  112  may identify the top and bottom of the normal range to be a certain percent of the historical average. In the example embodiment, the top is 110% of the historical average, while the bottom of the normal range is 90% of the historical average. In other embodiments, the top and bottom of the normal range may be another percentage. In even further embodiments, the top and bottom of the normal range may be a percentage range above and below the historical average or alternatively, the normalization may be conducted in other known manners other than by utilizing standard deviation and percentages. 
         [0020]    In yet another embodiment, the top and bottom of the normal range may be defined by user input via a user interface. The normal range and the utilization and depiction of the normal range by display program  112  is defined in greater detail below with regard to  FIG. 3 . 
         [0021]    In the example embodiment, display program  112  receives one or more data points from the one or more computing devices associated with the historical data (step  206 ). In the example embodiment, the one or more data points may be a representation of real time information such as usage statistics of the computing device (with regard to capacity/capability of the device). In the example embodiment, display program  112  normalizes the one or more data points in the same manner as the historical data. In an embodiment, the one or more received data points may represent information associated with a previous time period, such as past usage statistics pertaining to a certain period of time that has already passed. 
         [0022]    Display program  112  creates a visual representation of the one or more points (step  208 ). In the example embodiment, display program  112  creates a visual representation by graphically depicting the normal range within a larger range, with the larger range being input by an administrator, a developer or a user. The normal range may be depicted in manner so that it is readily apparent to a viewer of the visual representation (such as shading in the area of the larger range that represents the normal range). Referring to the example above, the normal range of two standard deviations (or 11.54) above and below 45 (i.e., 33.46 to 56.54) may be graphically depicted in a larger range of five standard deviations (28.85) above and below 45 (i.e., 16.15 to 73.85). In addition, the one or more points, for example, the points 42 and 20 may be additionally depicted on the visual representation. In this example, 42 is within the normal range, while 20 is an outlier (i.e., not in the normal range). Therefore, display program  112  may further highlight the outlier by changing the color of the depicted point. By visual depicting each received point against the visual representation of the normal range, a viewer of the visual representation is able to recognize an outlier. Furthermore, an administrator or developer may initially set the larger range to a specific range, however, a user may be given the option to alter the larger range to be a wider or narrower range. In the example embodiment, if the user chooses to alter the larger range, the larger range may be changed for all attributes across all computing devices so that visual representations of all attributes are depicted in a similar manner. 
         [0023]      FIG. 3  is an illustration of the display of normalized data in determining an outlier, in accordance with an embodiment of the invention. In the example embodiment, display is the display, such as on a monitor, on server  110  depicting the normalized data for computing device  120  and computing device  140 . In the example embodiment, visual representation  301  and visual representation  303  depict an example set of normalized data shown graphically. Visual representation  301  and visual representation  303  illustrate processor usage data associated with computing device  120  and memory usage (for example, RAM or persistent storage) located on computing device  120 . In the example embodiment, the top and bottom of the larger range (depiction range) is 5 standard deviations above and below the respective average or the processor usage data and for the memory usage. Furthermore, the normal range for the usage data and the memory usage is 2 standard deviations above and below the respective average. 
         [0024]    In the example embodiment, visual representation  302  and  304  depict an example set of normalized data corresponding to computing device  140 . As illustrated, the top and bottom of the larger range (depiction range) for the processor and memory usage is the same as computing device  120  in terms of standard deviation, however, the raw values represented by the standard deviations are different. In the example embodiment, the larger range for the memory usage and the computing device usage is 5 standard deviations above and below the respective average. In addition, the normal range for the computing device usage data and memory usage data is 2 standard deviations above and below the respective average. As depicted in visual representation  302  and  304 , a data point, which is a normalized representation of a raw usage data point of 35%, is visible as not within the normal range with regard to the processor usage data of computing device  104 , while the data points with regard to the processor usage data of computing device  120  and the usage data of both memory devices are shown as within the normal range. Therefore, a viewer of the visual representations is able to quickly detect an outlier (data point at 35%), which is outside the normal range of 2 standard deviations above and below the average. 
         [0025]    In addition, a visual representation such as the visual representation shown in  FIG. 3  may allow a user of server  110  to see multiple outliers and also see which outlier(s) is the most extreme. For example, a visual representation, such as the representation illustrated in  FIG. 3 , may show that both computing device  120  and computing device  140  have outliers with regard to CPU usage. For example, with the normal range being 2 standard deviations above and below the respective average, there may be an outlier (with regard to computing device  140 ) that is just slightly above 2 standard deviations from the averages, while there may also be an outlier (with regard to computing device  120 ) that is 5 standard deviations from the average. The visual representation of the CPU usage of each of the computing devices allows the user of server  110  to identify the two outliers and also that the outlier associated with computing device  120  is more severe and therefore may require more immediate attention.
