Working with the Dashboard

 

When you log in to the Edge Services Director interface, the first page that is displayed is the Dashboard page. After the deployment of the Edge Services Director application, if you have not discovered any SDGs, you are prompted to the next step of discovering devices. The link to the Service Gateways page, which is accessible by clicking the Build icon in the banner, is provided only for users with administrator privileges. The Dashboard page contains several monitors or frames. The following monitors are displayed on the Dashboard page:

SDG Views

The dashboard default view is tiled view. In tile view, a high-level, graphical view of the chassis is shown. It indicates the state of the interfaces. When the administrative and operational status of the interface is up, it is displayed in green. If the administrative status is down, the interface is displayed in grey. And, if the administrative status is up and operational status is down, the interface is displayed in amber. The image is a replica of the SDG. If you are connected to a virtual chassis, the image includes all the member switches of the virtual chassis.

The purpose of the view is to try and provide a comprehensive monitoring view of the health and status of deployed SDGs across the network. In this view all the managed SDGs are shown with their appropriate status and health based on the KPI template applied. This view helps the operator to know the health and status across the network, it provides with the operator to quickly see the macro level information, which allows the operator to further analyze the information provided and quickly navigate to individual SDGs and take any further corrective measure required. In tiled view, SDGs are by default sorted based on Red, Orange and Green. Consider a scenario in which an operator deploys n number of SDGs in a network. If the operator finds a difficulty in monitoring the status and health of the entire network, you can organize the dashboard with a tiled view to enable the operator to have a macro-level view on the network health.

You can change the view format to be tile view, group view, or band view. To change the view format, click the Maximize icon in the Service Gateway Health Status widget. The Service Gateway Health Status widget is popped out as a separate dialog box. You can click the Tile View, Group View, or Band View icons in the dialog box to organize the view appropriately in the Dashboard page. SDGs are deployed in the network as zones and the group view, which is a cluster of SDGs typically in a particular zone, helps the operators to quickly reach to a particular zone and find the status and health of the deployed SDG’s in that zone. By default it includes all the SDGs across network. Operator can able to view the SDGs based on particular zone. In Tile view, the Gateways/page box enables you to customize the number of SDGs displayed per page. You can display 25, 30, 35, or 40 SDGs per page. In Group view, the Groups/page box enables you to customize the number of SDG groups displayed per page. You can display 2, 4, 6, or 8 groups per page. The SDG groups are displayed in quadrants on the page.

Click the Maximum button at the upper right corner of each of the group boxes to expand and display the particular group in a separate window. SDGs span across the network based on zones. In this group view, all the managed SDG’s are grouped based on the zones. The corresponding SDG status and health is shown based on the KPI template applied.

Operators can quickly narrow down network discrepancies and failures based on a particular zone. Assume that in a particular zone, the KPI indication of SDGs in that group is not satisfactory. Using the group view, the operator can identify the particular zone in an efficient, optimal, and faster manner to view the status and health and analyze further. Logical grouping of SDGs, mostly based on zones, avoids the difficulty in monitoring the status and health of the entire network because the specific zone or group can be determined to investigate and drill down to the exact SDG that needs to be rectified.

A band view is also provided. In this view, each of the SDGs in a band are displayed spanning across the frame that shows the views. The bands are displayed one below the other. It provides a graphical display of the chassis in the network based on the bands, which are the different system severities or health conditions, such as red, orange, green, and gray. Double-clicking any of the SDGs in any of the views navigates you to the Monitoring page under Monitor mode for more detailed, in-depth diagnosis and debugging.

Service Delivery Gateway Alarms

Alarms are displayed below the health status line graph of the SDGs. Critical, major, and minor alarms are displayed in a pie chart with percentage values of each type of alarm. When you move the mouse over the segments of the pie chart, the total number of alarms of each type are displayed.

Filters

The SDG dashboard filter consists of two types, namely alarms and KPI templates, and favorite SDGs. The filters enable you to quickly and easily sort and segregate the appropriate SDGs that correspond to the KPI templates defined or alarms. The filter capability makes it easier for you to focus on only the SDGs that you are of relevance or interest. The SDGs status and health are colored based on the KPIs set by the operator. The dashboard filter operates in a logical OR format. If either of the filter conditions are satisfied, the display is modified to match the filter condition.

Assume that the CPU threshold value of one of the SDGs is set as 40 percent in a template. If the particular SDG exceeds that threshold, it needs to be displayed as red. When an operator logs into the dashboard and views the tiled pattern of display, all the SDGs are shown across the network. The operator is also viewing the critical SDGs and can decide to filter the SDGs based on the template. Based on the filter chosen, the SDGs are displayed in the dashboard view.

Select Favorite SDGs from the Filters box to display only the SDGs that you are interested in or are involved with managing in the entire network.

Select Alarms | KPIs from the Filters box to display SDGs that match with the criteria specified in the templates.

Click Clear Filters to remove the applied filters. You are prompted to confirm the deletion in such a case. A graphical representation of the components such as ADC and SFW that are defined in the KPI templates are displayed to the right of the Filters box on the Dashboard page.

To configure a filter, see Specifying KPI Template and Alarm Filters.

Specifying KPI Template and Alarm Filters

To specify KPI template and alarm filters for sorting the dashboard devices according to your needs:

  1. From the Dashboard page, select Alarms | KPIs from the Filter box. If you have already configured a filter, it is applied to determine the match criterion for displaying SDGs. The Filters window is displayed only if you cleared a previously configured filter or are configuring a filter for the first time.
  2. Select the Critical, Major, or Minor check boxes next to the Alarms field to filter SDGs based on the critical, major, or minor alarms generated for the devices.
  3. For the ADC, CGNAT, TLB, SFW, or HA sections, select the check boxes under the R, G, or O columns for the respective fields to cause SDGs that map with the settings defined in the KPI templates to be displayed in the dashboard view.

    R refers to SDGs with red status or catastrophic problems, G refers to SDGs with green status or fully functional condition, and O refers to SDGs with orange status or moderately critical problems.

    For the ADC section, you can choose the following:

    • CPU Status—Working state of the CPU for ADC

    • Service Pic Status—Operating status of the services PIC for ADC

    • VIP Status—Virtual IP address state used by virtual servers for ADC

    • Real Servers—Real servers used by ADC instances

    For the CGNAT section, you can choose the following:

    • CPU Status—Working state of the CPU

    • Service Pic Status—Operating status of the services PIC for CGNAT

    • Memory Status—Utilization of memory for CGNAT services

    • CPU Utilization—Usage of CPU for CGNAT operations

    For the TLB section, you can choose the following:

    • CPU Status—Working state of the CPU

    • Service Pic Status—Working status of the services PIC for TLB

    • Real Server Status—Status of real servers for TLB

    For the SFW section, you can choose the following:

    • CPU Status—Working state of the CPU

    • Service Pic Status—Status of services PIC for stateful firewall

    For the HA section, you can choose the following:

    • VRRP Status—Status of VRRP

    • CGNAT SFW HA—Inter-chassis high availability for CGNAT and firewalls.

  4. Click Apply to save the settings. Click Close to close the Filters window and return to the dashboard.

Service Delivery Gateways Count by Severity

A set of four boxes are displayed beneath the pane that shows the view of SDGs. These boxes are indicators for the overall set of SDGs that have been deployed. The boxes are colored as orange, red, green, or grey to indicate the health and performance of the SDGs based on the applied KPI templates. Red denotes an emergency condition, which is a system panic or other conditions that cause the routing platform to stop functioning. It also indicates that the device is offline or turned down. Orange denotes an alert, which can be conditions that must be corrected immediately, such as a corrupted system database. Green indicates a notice, which signifies conditions that are not error conditions but are of interest or might warrant special handling. It can also include a severity level equivalent to informational or debugging messages. Gray signifies an unknown or an unconnected device that is out of synchronization.

The configuration state of a device is shown as In Sync when the configuration information in all three repositories match (settings made using the devices CLI, Edge Servcies Director in Build mode, or Junos Space Network Management Platform). If there is a conflict between the configuration information in one or more of the repositories, the device configuration state is Out of Sync. An Out of Sync state is usually the result of out-of-band configuration changes—that is, configuration changes made to a device using a management tool other than Edge Services Director. You can resynchronize such devices to bring them back to be in synchronization. A number is displayed overlaying each of the boxes to specify the number of SDGs in each of the states or health conditions.

The paging controls that appear at the bottom of the SDG icons that are shown. You can use these controls to browse the SDGs when the inventory of SDGs is too large to fit on one page. The Page box lets you jump to a specific page of managed objects. Type the page number in the Page box and press Enter to jump to that page. The SDGs per page box enables you to customize the number of objects displayed per page. You can also navigate to the specific page of the dashboard view by typing the page number, if the SDGs span acros several pages. Otherwise, you can use the first, previous, next, and last page buttons to traverse across pages. The Refresh icon enables you to revise the display and show updated information.

Service Gateway Ticker Updates

The SDG dashboard ticker constantly updates with the event, messages and logs. This view can be added or removed from the Dashboard View by clicking the Add Widgets button or the cross mark (X) icon respectively. For a displayed syslog message, if you want to further analyze it for troubleshooting and diagnosing the cause of the error, you can use the options under the Monitor mode. At any given point in time, the latest ten messages are displayed and the older messages are flushed out. If you want to view historical messages, you can view the Fault Management, Performance Management, or Monitoring pages. By default, the standard Junos OS format for messages specifies the month, date, hour, minute, and second when the message was logged. Also, the event category and description are displayed.

Service Delivery Gateway Health Status Trend

The line chart displays the number of SDGs in each of the severity states. The severity is determined by the memory utilized on the routing engine, temperature, CPU load, and fan status. A fan running at normal speed is displayed in green. If the fan is running at maximum speed or not running at all, it is displayed in red. For a virtual chassis the status of the fans for the selected member is displayed. The SDG health status displays the operating condition and working efficiency in a color-coded form based on the configured KPI template for each of the individual SDGs.

A line graph is displayed with the horizontal axis showing the number of SDGs. The vertical axis shows the time in 24-hour clock format at which alarms have been raised or cleared for the SDGs. The green line denotes active SDGs, the orange line denotes warning messages, and the red line denotes critical problems with SDGs. Mouse over the dots on the graph to view details about the number of alarms at a particular point in time. Time is shown in increments of two hours on the horizontal axis, ending with the current time of the local clock on the system. You can expand or collapse the SDG Health Status pane by clicking the double right or double left arrows on the top-right corner of the pane.
