Configure a Data Source

npc represents each source of information as a registered data source. To load performance data, configure the data sources.
HID_View_a_List_of_Data_Sources
NetOps Portal
represents 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 Portal
dashboards, add, or register, the data sources.
Follow these steps:
  1. Hover over
    Administration
    ,
    Data Sources
    , and then click
    Data Sources
    .
    The
    Data Sources
    page appears.
  2. Click
    Add
    .
    The
    Add Data Source
    dialog opens.
  3. Complete the following fields:
    • Source Type
      Select 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 Monitor
      Default:
      Application Delivery Analysis
    • Status
      Defines the status of the data source.
      Values:
      • Enabled:
        NetOps Portal
        synchronizes the data source.
      • Disabled:
        NetOps Portal
        delays synchronization with the data source.
      Default:
      Enabled
    • Host Name
      Specifies 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.
    • Protocol
      Defines the communication protocol.
      Default:
      http
      For secure communication between
      NetOps Portal
      and this data source, select
      https
      .
      Prerequisite:
      HTTPS is enabled for
      NetOps Portal
      . The data source self-signed certificate or the CA intermediate/root certificate(s), if signed, must be imported before adding the data source. If
      NetOps Portal
      does not restart after importing the certificate, restart all
      NetOps Portal
      services.
      For more information, see Enable HTTPS for
      NetOps Portal
      .
    • Port
      Specifies the port for the data source.
    • Display Name
      Specifies the display name for the data source. By default,
      DX NetOps Performance Management
      combines 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 Aggregator
      Select 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:
      Cleared
      Required:
      No
      Automatic 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 Management
      creates a discovery profile that includes the IP addresses of the devices. This discovery profile attempts discovery once per day.
    • Web Console
      If the Web Console is on a different system than the data source, clear the
      Same as data source
      check box, and then specify another
      Host Name
      and
      Port
      for the data source console.
      Default:
      Selected
      Required:
      No
      Use 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 device
      When the data aggregator finds a device component that is no longer present in the environment, that status of the component is set to
      Not 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:
      Cleared
      If 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 Spectrum
      data sources only)
      Synchronize device life cycle state from Spectrum
      To enable
      DX NetOps Spectrum
      to control the life cycle state of items in
      DX NetOps Performance Management
      , select this option.
      Default:
      Cleared
      For more information, see Manage Device Life Cycles.
  4. (Optional) Test the connection by clicking
    Test
    .
  5. Click
    Save
    .
    If the data source is enabled, data appears in
    NetOps Portal
    after 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
NetOps Portal
.
To confirm the proper registration and connection of a data source, on the
Data Sources
page, select the data source that you want to test, and click
Test
.
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:
  1. On the
    Data Sources
    page, select the data source that you want to edit, and then click
    Edit
    .
    The
    Edit Data Source
    dialog opens.
  2. Complete the fields on the dialog, and then click
    Save
    .
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 the
    same
    NetOps Portal
    instance
    , unexpected behavior might occur. You can however register deleted data sources to another
    NetOps Portal
    instance. Instead, consider removing a data source temporarily by setting its
    Status
    to "Disabled".
  • If
    View Suppression
    is enabled,
    NetOps Portal
    suppresses 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 in
    NetOps Portal
    .
    For more information about this setting, see Customize Your User Settings.
  • Before deleting a
    DX NetOps Network Flow Analysis
    data source, see Results of Unregistering.
Follow these steps:
  1. On the
    Data Sources
    page, select the data source that you want to delete, and then click
    Delete
    .
    The
    Delete Data Source
    dialog opens.
  2. Click
    Yes
    .
The data source is deleted.
