Context pages provide focused performance and status data that is scoped to a specific item, such as a single router or server.
You can often access more information about individual managed items from dashboards. Most dashboards are composed of views of summary data, such as hourly rollups or averages from a group of items. When additional data is available from the data source and you have the Drill into Views role right, you can drill down into the context pages. Context pages provide focused performance and status data that is scoped to a specific item, such as a single router or server.

Extended Flow Views
You can drill down
DX NetOps Network Flow Analysisdata for an interface within
NetOps Portalwithout having to navigate to
DX NetOps Network Flow Analysis. The interface context page supports the following views:
- IP PerformanceProvides a broad summary of information for the selected interface extracted from the flow data such as Top N Protocols, Top N Hosts, Top N Conversations and Top N ToS values. The interface also provides the interface utilization and discards details for the same interface provided through the data aggregator.To navigate to the context page of the protocol or host, you can select the required protocol or host from any of the views.If the data source isDX NetOps Network Flow Analysis10.x and higher, the links in the charts and tables in the IP Performance page open the corresponding network flow pages withinDX NetOps Performance Management. If the data source isDX NetOps Network Flow Analysis9.x and earlier, the links open the corresponding pages in theDX NetOps Network Flow Analysisconsole.
- ForDX NetOps Network Flow Analysis10.x and higher data sources, the following interface pages are available:
- Network Flow ProtocolProvides trends and next level drill downs (hosts and conversations) for the selected Protocol in the table. Host and conversation trend tables provide utilization information in the context of the selected Protocol.
- Network Flow HostProvides host trends and protocol stacked trends for the selected Host in the table.
- Network Flow ConversationProvides host trends and protocol stacked trends for the selected Conversation in the table.
- Network Flow ToSProvides trends and next level drill downs (hosts and conversations) for the selected Type of Service(ToS) in the table. Host and conversation trend tables provide utilization information in the context of the selected ToS.
For all context pages, selecting a row in the top table view sets the corresponding context for the other views in the page. You can change the measurement (Rate/Bytes/Utilization) and direction (In/Out) in the settings for each of the views.
You can send or schedule these views in a report by email. By default, the first row is selected in the Top table and the data for the following views are of the first-row selection.

Filter Data from a Narrow Context
The views on context pages show filtered data from a narrow context, such as a view of data from a single managed item. Determine the source of a performance problem by drilling down into specific data using the links.
In some table views, right-click the name of an item (the link). For example, right-click the link that corresponds to an item name in the
Inventorysection. In the resulting menu, select a related context page, containing more granular data.
Pick a Context
You can pick a context using the context picker that is available next to the name of the managed item. Context pickers are also available for the children of the managed item.
To pick a different context, click
Change, select the context, and then click
Some context pages, such as routers and servers, include the reachability status of the device. The reachability status indicates whether
DX NetOps Performance Managementis able to reach the device during the selected time range of the context page.
For more information, see Reachability Status and Contact Status.
Manage the Tabs on a Context Page
Prerequisite:You are an Administrator or Designer or you have the Edit Context Pages and Drill into Views role rights.
Unlike standard dashboard pages, item context pages are clustered in sets of tabbed pages. Editing a context page entails managing (adding or editing) these tabs. You can edit the predefined tabs and can change the views that are displayed on those tabs. You can add tabbed pages. You can also rearrange the tabs in an item context to change their order.
Based on the device service information, the data aggregator automatically classifies manageable devices as Router, Switch, and Server primary device types. Also, where applicable, managed devices are associated with context types (Firewall, Load Balancer, Wireless Controller, and Wireless Access Point). The associated context types, including primary device types, appear listed in a column within device inventory tables.
When you add or edit tabs for a device context page, you can associate them with a primary device type or context type. Tabs that are associated with a primary device type or context type appear on the device context pages that are associated with the specified types.
- If you add or edit a tab and associate it with the server type, it appears for all server types.
- If you add or edit a tab for a server type and associate it with firewall, it appears only for all server, firewall types.
- If you add or edit a tab for a router type and associate it with wireless access point, it appears only for all router, wireless access point types.
- If you add or edit a tab for a server type and associate it with wireless controller, it appears only for all server, wireless controller types.
Associating a tab with a primary device type or context type impacts all manageable devices that are associated with the primary device type and context type. For change control, minimize edits to the tab after you associate it with a primary device or context type.
Revert changes to all tabs in the current context by selecting
Restore Tabs to Defaultsfrom the
Modifications apply to the current tenant.
Follow these steps:
- Navigate to the item context whose page you want to edit. For example, click the link for a router on a dashboard to open the Router context pages.The tab that is selected includes anEditicon so that you can access theEditmenu.
- Select the tab that you want to modify.TheEditicon appears.
- Click theEditicon, and then selectAdd TaborEdit Tab.
- (Optional) Select one of the default tab templates fromDefault Tab Templatesmenu. Each template populates the page with the default views for that type of page.
- Change the tab title. A title is required.The tab title determines the name that appears at the top of the tabbed context page.
- (Optional) To associate the tab with a primary device type or context type, select a context page type from theContext Typesmenu.
- Select a layout template for the page from the layout buttons in theLayoutsection.
- Remove unwanted views from the page if desired. In theLayoutpane, click one of the following:
- Clear Layout:Changes the positioning of all views on the page.

- Speed In (bps)
- Speed Out (bps)
If you cleared
Speed In (bps)or
Speed Out (bps), the change takes a few minutes to appear.
Apply a Business Hours Filter to a Context Page
To show data in a context page for particular business hours, you can apply a business hours filter to it. This sets the reporting profile that persists during your user session. The filter filters the data that appears in the views on the context page. You cannot modify the business hours within a view’s configuration.
You can also set the reporting profile that persists during your user session by selecting a site group that is associated with a business hours definition in context.
When navigating to a dashboard page from a context page, the applied business hours on context pages (session business hours filter) supersede the page context for the site group if the site group is associated with a business hour filter.
Applied business hours filters to context pages remain applied when switching between context pages, navigating between dashboards, and changing time ranges. Moving to a top-level dashboard or changing the context page removes the business hours filter.
Follow these steps:
- On the context page to which you want to apply a business hours filter, click theApply Business Hours(clock) switch icon in the upper-right corner of the page.This icon indicates when business hours are and are not being applied to a view on a dashboard.The Apply Business Hours dialog opens.If you have applied a business hours filter with a time zone to the context page,Context Business Hourshows the applied business hours filter and time zone. Otherwise,No business hours selecteddisplays. If you have applied a business hours filter with a time zone as part of your user session,Session Business Hourshows the applied business hours filter and time zone.
- Complete the following fields, and then clickApply:
- Apply Business Hour FilterEnable this option. By default, business hours are not enabled.
- Context Filter TypeDefines the profile of the context filter type for the business hours filter.Options:
