Configure a Data Source
npc represents each source of information as a registered data source. To load performance data, configure the data sources.
NetOps Portalrepresents sources of information as registered data sources. To load performance data, register these as data sources.
You can also use this procedure to configure your data source for secure communication using Hypertext Transfer Protocol Secure (HTTPS).
The following procedures require the Administrator role:
Register a Data Source
To view collected data on
NetOps Portaldashboards, add, or register, the data sources.
Follow these steps:
- Hover overAdministration,Data Sources, and then clickData Sources.TheData Sourcespage appears.
- ClickAdd.TheAdd Data Sourcedialog opens.
- Complete the following fields:
- Source TypeSelect the type of data source.This list includes all possible data sources. The list does not show data sources that already have reached the registration limit.Values:Application Delivery Analysis, Application Performance Management, Catalyst Connector, Network Flow Analysis, Spectrum Infrastructure Manager, Unified Communications MonitorDefault:Application Delivery Analysis
- StatusDefines the status of the data source.Values:
- Enabled:NetOps Portalsynchronizes the data source.
- Disabled:NetOps Portaldelays synchronization with the data source.
- Host NameSpecifies the hostname for the data source. If you are registering a data aggregator data source, specify the IP address or hostname of the data aggregator host. If you are registering a fault-tolerant data aggregator, specify the proxy server. For other data sources, specify the IP address or hostname of the management console.If you are planning to enable HTTPS for this data source, enter the hostname that the certificate uses. Typically this is the fully qualified domain name (FQDN), but this depends on the form of the name that was used when the certificate was created.For more information about fault-tolerant data aggregators, see Fault Tolerance.
- ProtocolDefines the communication protocol.Default:httpFor secure communication betweenNetOps Portaland this data source, selecthttps.Prerequisite:HTTPS is enabled forNetOps Portal. The data source self-signed certificate or the CA intermediate/root certificate(s), if signed, must be imported before adding the data source. IfNetOps Portaldoes not restart after importing the certificate, restart allNetOps Portalservices.For more information, see Enable HTTPS forNetOps Portal.
- PortSpecifies the port for the data source.
- Display NameSpecifies the display name for the data source. By default,DX NetOps Performance Managementcombines the data source type and the hostname to create the display name. You can specify another name. For example, instead of [email protected], specify the name for the data source as NFA_NewYork.
- Contribute inventory to Data AggregatorSelect to contribute new data source inventory to the data aggregator. When cleared, the existing inventory remains the same, and new data source inventory is not contributed to the data aggregator.Default:ClearedRequired:NoAutomatic synchronization includes only devices that are discovered after you select this option. To discover previously discovered devices, perform a full synchronization of the data aggregator.DX NetOps Performance Managementcreates a discovery profile that includes the IP addresses of the devices. This discovery profile attempts discovery once per day.
- Web ConsoleIf the Web Console is on a different system than the data source, clear theSame as data sourcecheck box, and then specify anotherHost NameandPortfor the data source console.Default:SelectedRequired:NoUse this parameter in cases when network address translation is deployed.
- (Data aggregator data sources only)Synchronize component items that are not currently present on the monitored deviceWhen the data aggregator finds a device component that is no longer present in the environment, that status of the component is set toNot Present. By default, the data aggregator does not synchronize these items because data can no longer be collected for the item. Historical data that has not reached the data retention limit is still available for these items.Default:ClearedIf the properties of an active component match the identifying properties of the not-present component, the components are indistinguishable. Data from the not-present component might contribute to group-based dashboards instead of data from the active component. Enable this feature only under the following circumstances:
- You want to report on historical data for no-longer-present items in the environment.
- You want to ensure that not-present items do not conflict with an actively-monitored item.
- You want to identify not-present items so that you can exclude them from groups.
- (DX NetOps Spectrumdata sources only)Synchronize device life cycle state from SpectrumTo enableDX NetOps Spectrumto control the life cycle state of items inDX NetOps Performance Management, select this option.Default:ClearedFor more information, see Manage Device Life Cycles.
- (Optional) Test the connection by clickingTest.
- ClickSave.If the data source is enabled, data appears inNetOps Portalafter the next synchronization.
Test the Data Source Connections
If data source registration does not complete successfully, determine the reason for the failure by testing the data source connection. The test validates version compatibility and verifies that the data source is not registered with a different instance of
To confirm the proper registration and connection of a data source, on the
Data Sourcespage, select the data source that you want to test, and click
If the test fails, verify that the server name or IP address is accurate for the source type.
For more information, see Data Source Test Fails.
Edit a Data Source
The changes that you make to a data source apply to the system after the next synchronization.
Follow these steps:
- On theData Sourcespage, select the data source that you want to edit, and then clickEdit.TheEdit Data Sourcedialog opens.
- Complete the fields on the dialog, and then clickSave.
Delete a Data Source
Users with the Administrator role and the Delete Data Sources role right can delete data sources. This role right is not granted by default. To delete a data source, assign this role right to the Administrator role.
- Deleting, or unregistering, a data source does not remove everything from the system.
- If you attempt to register a deleted (unregistered) data source at a later time to thesame, unexpected behavior might occur. You can however register deleted data sources to anotherNetOps PortalinstanceNetOps Portalinstance. Instead, consider removing a data source temporarily by setting itsStatusto "Disabled".
- IfView Suppressionis enabled,NetOps Portalsuppresses views that are associated with the deleted data source. As a result, deleting a data source can cause some menus and dashboards to become unavailable. A dashboard, context tab, or custom menu must contain at least one view that is not suppressed. Otherwise, the menu item does not appear inNetOps Portal.For more information about this setting, see Customize Your User Settings.
- Before deleting aDX NetOps Network Flow Analysisdata source, see Results of Unregistering.
Follow these steps:
- On theData Sourcespage, select the data source that you want to delete, and then clickDelete.TheDelete Data Sourcedialog opens.
The data source is deleted.
