special purpose or general - purpose computer including computer hardware , such as , for example , one or more processors and system memory , as discussed in greater detail below . embodiments within the scope of the present invention also include physical and other computer - readable media for carrying or storing computer - executable instructions and / or data structures . such computer - readable media can be any available media that can be accessed by a general purpose or special purpose computer system . computer - readable media that store computer - executable instructions are computer storage media ( devices ). computer - readable media that carry computer - executable instructions are transmission media . thus , by way of example , and not limitation , embodiments of the invention can comprise at least two distinctly different kinds of computer - readable media : computer storage media ( devices ) and transmission media . computer storage media ( devices ) includes ram , rom , eeprom , cd - rom , solid state drives (“ ssds ”) ( e . g ., based on ram ), flash memory , phase - change memory (“ pcm ”), other types of memory , other optical disk storage , magnetic disk storage or other magnetic storage devices , or any other medium which can be used to store desired program code means in the form of computer - executable instructions or data structures and which can be accessed by a general purpose or special purpose computer . a “ network ” is defined as one or more data links that enable the transport of electronic data between computer systems and / or modules and / or other electronic devices . when information is transferred or provided over a network or another communications connection ( either hardwired , wireless , or a combination of hardwired or wireless ) to a computer , the computer properly views the connection as a transmission medium . transmissions media can include a network and / or data links which can be used to carry or desired program code means in the form of computer - executable instructions or data structures and which can be accessed by a general purpose or special purpose computer . combinations of the above should also be included within the scope of computer - readable media . further , upon reaching various computer system components , program code means in the form of computer - executable instructions or data structures can be transferred automatically from transmission media to computer storage media ( devices ) ( or vice versa ). for example , computer - executable instructions or data structures received over a network or data link can be buffered in ram within a network interface module ( e . g ., a “ nic ”), and then eventually transferred to computer system ram and / or to less volatile computer storage media ( devices ) at a computer system . thus , it should be understood that computer storage media ( devices ) can be included in computer system components that also ( or even primarily ) utilize transmission media . computer - executable instructions comprise , for example , instructions and data which , when executed at a processor , cause a general purpose computer , special purpose computer , or special purpose processing device to perform a certain function or group of functions . the computer executable instructions may be , for example , binaries , intermediate format instructions such as assembly language , or even source code . although the subject matter has been described in language specific to structural features and / or methodological acts , it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the described features or acts described above . rather , the described features and acts are disclosed as example forms of implementing the claims . those skilled in the art will appreciate that the invention may be practiced in network computing environments with many types of computer system configurations , including , personal computers , desktop computers , laptop computers , message processors , hand - held devices , multi - processor systems , microprocessor - based or programmable consumer electronics , network pcs , minicomputers , mainframe computers , mobile telephones , pdas , tablets , pagers , routers , switches , and the like . the invention may also be practiced in distributed system environments where local and remote computer systems , which are linked ( either by hardwired data links , wireless data links , or by a combination of hardwired and wireless data links ) through a network , both perform tasks . in a distributed system environment , program modules may be located in both local and remote memory storage devices . fig1 illustrates an example computer architecture 100 that facilitates time - based navigation within resource utilization data . referring to fig1 , computer architecture 100 includes components 101 ( 101 a - 101 d ). the ellipses between 101 c and 101 d represents that that are one or more additional components can exist . thus , there may be as few as two such components , but there might also be as many as thousands or perhaps more components . accordingly , fig1 should only be interpreted as an example of multi - components computer architecture . each of the depicted components may be separate independent computer systems or computer components of a single computer system . for example , components 101 can be gpus , hard disks , cpus , or even cores of a cpu . each of the depicted components is physically connected or connected to one another over ( or is part of ) a network , such as , for example , a local area network (“ lan ”), a wide area network (“ wan ”), and even the internet . accordingly , each of the depicted components as well as any other connected components and their sub - components , can create message related data and exchange message related data ( e . g ., internet protocol (“ ip ”) datagrams and other higher layer protocols that utilize ip datagrams , such as , transmission control protocol (“ tcp ”), hypertext transfer protocol (“ http ”), simple mail transfer protocol (“ smtp ”), etc .) over the network . as depicted in fig1 , computer architecture 100 includes utilization module 103 , navigation module 105 , data storage space 107 , and display device 109 . components 101 can output raw computing activities 104 . utilization module 103 is configured to receive raw computing activities 104 from components 101 . raw computing activities 104 may be any type of computing activities , including reading or writing operations to hard disks , calculations by cpu , or transmissions of data over a network . upon receiving raw computing activities 104 , utilization module 103 can generate resource utilization data 106 based on raw computing activities 104 . resource utilization data 106 can indicate different performances of components 101 including executions , synchronizations , input / output operations , sleep time , memory management , preemption , or ui processing . in some embodiments , navigation module 105 generates diagnostic data trace 108 and submits diagnostic data trace 108 to display device 109 . diagnostic data trace 108 can include resource utilization data 106 . in addition , the navigation module 105 can receive different time ranges 102 . a user can select the time range , for example , when the details of the resource utilization data within the time range are of interest . four time ranges ( 102 a , 102 b , 102 c , and 102 d ) are illustrated in fig1 . however , the ellipses represents that other time ranges can exist . in one embodiment , upon receiving time range 102 a , navigation module 105 submits extents 110 of selected time range ( 102 a ) together with the diagnostic data trace within selected time range 112 to display device 109 . once the user chooses another time range , as an example , 102 b , navigation module 105 submits extents 114 of the extents of the newly selected time range ( 102 b ) and the diagnostic data trace within newly selected time range 116 to display device 109 . in one embodiment , navigation module 105 may communicate with data storage space 107 . data storage space 107 may store resource utilization data 106 , time ranges 102 , or diagnostic data trace 108 and provides such information upon the request from navigation module 105 . fig2 illustrates a flow chart of an example method 200 for time - based navigation within resource utilization data . as method 200 may be performed by navigation module 105 in fig1 , method 200 will now be described with frequent reference to computer architecture 200 of fig2 . method 200 includes an act of presenting a diagnostic data trace at a display device , the diagnostic data trace including the resource utilization data ( act 201 ). for example , navigation module 105 can display portions of diagnostic data trace 108 . portions can be evenly spaced and marked with time intervals . in some embodiments , resource utilization data 106 are color coded . color coding can include assigning different presentation colors to resource utilization data corresponding to different components 101 . for example , the utilization data generated by the cpu may be marked as red and the utilization data generated from the gpu may be marked as green . method 200 includes an act of selecting a current visible time range within diagnostic data trace ( act 202 ). for example , a user can select and submit time range 102 a to navigation module 105 . to select the current visible time range , the user may input the start and end value of the current visible time range . for example , the user may simply input “ 12000 ” and “ 12300 ” to select the time range from 12000 milliseconds to 12300 milliseconds . alternatively , the user may press the mouse at a desired start position at the diagnostic data trace , drag it to a desired end position , and then release the mouse . method 200 includes an act of presenting resource utilization data within the current visible time range along with the diagnostic data trace at display device , each extent of the current visible time range having a resizing control displayed on the diagnostic data trace ( act 203 ). for example , receiving a selected current visible time range 102 a from the user , navigation module 105 presents extents of selected time range 110 and diagnostic data trace within selected time range 112 along with diagnostic data trace 108 at the display device . each extent of the current visible time range has a resizing control displayed on the diagnostic data trace . as one embodiment , the resizing control may be shaped as a small red rectangle so that the user may easily click the resizing control . the diagnostic data trace within the current visible time range is visually distinguished from the diagnostic data trace outside the current visible time range . for example , in one embodiment , the diagnostic data trace within the current visible time range may be filled with red and the diagnostic data trace outside the current visible time range may be filled with light pink ( although other combinations of visually distinguishing indicators [ color , size , shape , etc .] are also possible ). the extents of the current visible time range can also be displayed with marks indicating the start and end value of the extents . in some embodiments , when the current visible time range is selected , the resource utilization data corresponding to each of components 101 are displayed in different data traces in greater details . multiple ticks spaced evenly indicating the time interval and marks indicating the start time and end time of the current visible time range are displayed along the different traces . method 200 includes an act of receiving a selection of a new visible time range ( act 204 ). for example , the user may reselect and submit time range 102 b to navigation module 105 since the user &# 39 ; s interest in different portions of the resource utilization data might change over time . method 200 includes an act of modifying the current visible time range in response to the selection of new visible time range ( act 205 ). the act of modifying the current visible time range further including an act of changing at least one of the extents of current visible time range to a corresponding extent of the new visible time range ( act 206 ) and an act of displaying resource utilization data within new visible time range along with the diagnostic data trace at the display device , each extent of the new visible time range having a resizing control displayed on the diagnostic data trace ( act 207 ). for example , when navigation module 105 receives new time range 102 b , navigation module 105 submits extents of selected time range ( based on time range 102 b ) 114 and diagnostic data trace within selected time range ( based on time range 102 b ) 116 to display device 109 . in response to the selection of the new visible time range , navigation module 105 may modify the current visible time range . in modifying the current visible time range , based on the requests from the user , navigation module 105 may change one or more of the extents of the current visible time range or pan and zoom the current visible time range . in some embodiments , in changing the extents of the current visible time range , the user may click the resizing control of one extent and drag the extent to a desired position . alternatively , the user may use a keyboard arrow key to move the extent after click the extent . for example , when the user clicks the resizing control of the left extent , the user may use “←” key to change the current visible time range ( from 12000 to 12300 milliseconds ) to a new visible time range ( from 11800 to 12300 milliseconds ). in some embodiments , in panning the current the visible time range , the user may click an area outside the current visible time range but within the diagnostic data trace to move the center of the current visible time range to the position where clicking occurred . the user may also click an area within the current visible time range and drag the current visible time range to a desired position . alternatively , the user may also use a keyboard arrow key to move the current visible time range after click the current visible time range . in addition , the user may simply input the start and end value of the new visible time range . for example , the user may input new start value and end value as “ 11000 ” and “ 17000 ” to select a new visible time range from 11000 to 17000 milliseconds . the navigation module then may display the resource utilization data within the new visible time range . similarly , the new visible time range is displayed along with the diagnostic data trace and each extent of the new visible time range has a resizing control displayed on the diagnostic data trace . fig3 illustrates a screen shot of an example user interface 300 at the display device of fig1 when example computer architecture 100 performs example method 200 . user interface 300 will be described with respect to the acts of method 200 and elements of computer architecture 100 . in some embodiments , as depicted in fig3 , the user interface may display diagnostic data trace 301 at the top of the screen . resource utilization data 302 may be displayed in a color ( e . g ., green ) within diagnostic data trace 301 . upon selection of the current visible time range , rectangular box 303 or other symbols may be displayed to indicate the current visible time range . the rectangular box may be in a color visually distinguishable with the color of the resource utilization data . each extent of the current visible time range has resizing control 304 that may be in a form of thumb . meanwhile , the resource utilization data within the current visible time range ( i . e ., within the rectangular box ) may be in a color substantially different from the color of the extents of the current visible time range and the color of the resource utilization data outside the time range . upon determination of the current visible time range , the detail resource utilization data of each corresponding components within the time range may be displayed as multiple traces 307 below diagnostic data trace 301 . in one embodiment , the names and ids 305 of the components may be displayed beside multiple traces 307 . in some embodiments , different performances 306 may be assigned with different presentation colors , 306 a , 306 b , 306 c , 306 d , 306 e , 306 f , 306 g . for example , execution of applications may be assigned with red and synchronizations may be green . fig4 illustrates an example screen shot of the diagnostic data trace displayed with a selected time range . as the diagnostic data trace and the selected time range may be generated by navigation module 105 , screen shot 400 will now be described with frequent reference to computer architecture 200 of fig2 . as depicted , resource utilization data may be displayed at a diagnostic data trace . multiple ticks 403 may be displayed and evenly spaced to indicate the total length of the diagnostic data trace is 100 . 0 seconds and the diagnostic data trace is evenly divided by the ticks into four equal portions . the resource utilization data corresponding to different components 101 may be assigned with different colors , 402 a , 402 b , and 402 c . although only three colors are showed , this principle described herein may apply to any interface showing more than three different performances . upon the selection of the current visible time range , current visible time range 404 is displayed at the diagnostic data trace . each of the extents has a resizing control 406 . resource utilization data within the time range ( 405 a , 405 b , 405 c ) is visually distinguished with the resource utilization data outside the time range . in one embodiment , start time 408 and end time 407 of the current visible time range may be marked . the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics . the described embodiments are to be considered in all respects only as illustrative and not restrictive . the scope of the invention is , therefore , indicated by the appended claims rather than by the foregoing description . all changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope .
