Performance View has a single main window from which you access all performance information. The following image identifies the major user interface elements in the main window:
 SPEC--pview_uioverview_oth 
The status bar displays the current state of Performance View and, when applicable, the status of the current health report. The connection status icon is color-coded, indicating the status of the connection to the 
SpectroSERVER
:
  •  
    Green
    Normal
  •  
    Yellow
    Using backup 
    SpectroSERVER
     
  •  
    Red
    Contact lost
The tabs in the main window provide detailed information about 
SpectroSERVER
 performance. The information is presented in bar graphs, line graphs, and text.
Bar graphs appear on the Main tab. These graphs use data that is collected in 10-minute running averages. All other attributes and graphs use data collected every 10 seconds.
Line graphs on the CPU, Memory, Disk, Network, Poll/Log, and Timer/Notify tabs display data that is collected over 60 minutes. Only the most recent 60 minutes of data is displayed.
For single-line graphs, instantaneous values are shown in a text box. For multiple-line graphs, instantaneous values are shown in color-coded labels, where each label represents the instantaneous value of its associated line.
Line graphs also provide high-level marks and tooltips. High-level marks represent the highest data value that was collected since data collection began. You can reset the high-level marks and can make other changes to the axes of line graphs. Multiple CPUs and disk drives can be graphed in the same chart.
Main Tab
The Main tab contains a Physical Memory Utilization graph, a CPU Utilization graph, a Disk Utilization graph, and general data.
 SPEC--pview_tabmain_scr.png 
Check the Main tab for the following information:
  •  
    Physical Memory Utilization
    Displays the amount of physical memory that is used by the 
    SpectroSERVER
     and other processes that are running on the server to which Performance View is connected.
  •  
    CPU Utilization
     
    Displays the percentage of total CPU processing power that is used by the 
    SpectroSERVER
     and other processes that are running on the server.
  •  
    Disk Utilization
    Displays the amount of disk read/write access capacity that is used on the server.
Check the General Data panel for the following information:
  •  
     
    DX NetOps Spectrum
     Version
    Specifies the version of 
    DX NetOps Spectrum
     that is installed on the server.
  •  
     
    SpectroSERVER
     Uptime
    Specifies the amount of time that the server has been running. The format for Uptime is <days>d <hours>h <minutes>m.
  •  
    Number of Clients Connected
    Specifies the total number of clients that are connected to the selected 
    SpectroSERVER
    .
  •  
    Number of Models
    Specifies the total number of models, including device models and other models.
  •  
    Number of Accountable Models
    Specifies the total number of models that are included in the device count calculation (used in 
    DX NetOps Spectrum
     software licensing).
  •  
    Number of Device Models
    Specifies the total number of physical devices that are modeled with model types derived from the Device model type.
  •  
    Number of Polled Models
    Specifies the number of models whose Polling Status is set to TRUE and that have a non-zero polling interval.
  •  
    Number of Polled Attributes
    Specifies the current number of attributes that the 
    SpectroSERVER
     is polling.
  •  
    Number of Logged Attributes
    Specifies the current number of attributes that the 
    SpectroSERVER
     is logging.
     Polled attributes are used to determine whether a device is up or down (for fault isolation). Logged attributes are used to gather statistical information. Logging of polled attributes is optional, and logged attributes are not always polled.
CPU Tab
The CPU tab contains a CPU Utilization graph and information on the top CPU users.
  •  
    CPU Utilization
    Displays the 
    SpectroSERVER
     usage as a percentage of the total CPU capacity. Each system CPU is included in the line graph.
  •  
    Top CPU Users 
    Displays the top 10 CPU users from highest to lowest and the CPU utilization percentage for each.
Memory Tab
The Memory tab provides the following information:
  •  
    SS Memory Utilization
    Displays the amount of memory that the 
    SpectroSERVER
     is using.
  •  
    Paging Activity
    Displays total paging activity.
  •  
    Top Memory Users
    Displays the top 10 memory users (from highest to lowest) and the memory that each process is using.
Disk Tab
The Disk Utilization graph on the Disk tab displays the percentage of disk read/write capacity that is being used.
 SPEC--pview_tabdisk_scr 
Network Tab
The Network tab contains a Network I/O graph and a Traps Received graph. Check this tab for the following information:
  •  
    Network I/O
    Reflects VNM read/write bytes only. This graph does not include traffic from any other sources.
  •  
    Traps Received
    Displays the number of unsolicited messages, such as SNMP traps, that the VNM receives.
Poll/Log Tab
The Poll/Log tab contains the following graphs:
  •  
    Poll Latency
    Displays the average poll latency, which is the interval in seconds between when a scheduled polling thread is expected to complete the actual completion time.
  •  
    Poll Threads in Use
    Displays the number of poll threads in use. A poll thread is allocated to every polling operation.
  •  
    Log Latency
    Displays the average log latency, which is the interval in seconds between when a scheduled logging thread is expected to complete and the actual completion time.
  •  
    Log Threads in Use
    Displays the number of log threads that are in use. A log thread is allocated to every logging operation.
Health Report Tab
The Health Report tab displays status information about the current health report. After the data has been collected, the report and the average percentage of 
SpectroSERVER
 capacity during the reporting period are displayed on the tab.
Timer/Notify Tab
The Timer/Notify tab lets you monitor the performance of timer and notification threads.
 
Note: 
By default, this tab is not shown. To display it, you must select it from the View menu.
 SPEC--pview_tabtimernotify_scr 
The graphs provide the following information:
  •  
    Timer Latency
    Displays the average timer latency in seconds. Time latency is the interval between when a scheduled timer thread is expected to complete and the actual time of completion.
  •  
    Timer Threads in Use
    Displays the number of timer threads in use.
  •  
    Notification Latency
    Displays the average notification latency in seconds. Notification latency is the interval in seconds between when a scheduled notification thread is expected to complete and the actual time of completion.
  •  
    Notification Threads in Use
    Displays the number of notification threads in use.
View Connection Details for the Connected SpectroSERVER
To determine the status of the connection between Performance View and the 
SpectroSERVER
, examine the connection status icon SPEC--connectionstatus_ICO.
The icon appears in the bottom right corner of the Performance View user interface.
The color of the icon indicates the status:
  •
