Configure a data input for streaming events from Microsoft Azure Event Hubs to your ServiceNow instance.

Before you begin

Important: Health Log Analytics does not support IPv6. To work with the application, configure the MID Server to IPv4.
  • You must have an installed and configured MID Server with the log ingestion capability enabled.
  • If the IP address of the MID Server is exposed by network address translation (NAT), a load balancer or a similar device, it must have a public IP address. In the MID Server properties, add a property named mid.public_ip with the public IP address as the value. For more information, see Create a MID Server property.

Procedure

  1. Navigate to All > Health Log Analytics > Data Input > Data Inputs.
  2. On the Data Inputs page, select New.
  3. Choose the Microsoft Azure Event Hubs data input.
  4. On the form, fill in the fields.
    For a description of the fields, see Microsoft Azure Event Hubs data input configuration fields.
  5. (Optional) Select Advanced to set additional configuration fields.
    For a description of the fields, see Microsoft Azure Event Hubs data input configuration fields. For information about configuring the advanced settings later, see Configure advanced settings for Microsoft Azure Event Hubs data inputs.
  6. On the Query settings tab, fill in the fields.
    For a description of the fields, see Microsoft Azure Event Hubs data input configuration fields.
  7. On the Transport tab, fill in the fields.
    For a description of the fields, see Microsoft Azure Event Hubs data input configuration fields.
  8. Select Save.
    Health Log Analytics adds the data input record to the Data Inputs table.
  9. Ensure that the data input is configured correctly by selecting Test connection.

    Health Log Analytics tries to connect the MID Server to the data repository.

    If the data input is configured to run on a MID Server cluster, the system tries to connect all the MID Servers contained in the cluster to the repository. The cluster passes the test if at least one of its MID Servers gets connected. This feature is supported in the Health Log Analytics application, Version 26.0.17 - February 2023 and later, available from the ServiceNow Store.

    • If the connection was established, the Test connection button is turned off and the Publish button is enabled.
    • If the connection failed, the reason for the failure displays in the Error message field. Resolve the issue, select Save if you modified the configuration, and then select Test connection to test the connection again.
      Note: You can only publish the data input configuration when the connection is created successfully.
    Note: You can revert to the last published configuration by selecting Revert Changes. This option is available only when you're modifying a configuration that has been published previously.
  10. Select Publish to publish the data input to the MID Server.

Result

The data input starts streaming log data from Microsoft Azure Event Hubs to your instance.

Note: If the Health Log Analytics AI engine is down and data has stopped streaming, a notification appears at the top of the data input configuration page. When this happens, contact ServiceNow support.

What to do next

Make sure that the data input is streaming data.
