    • Configure advanced settings for data inputs used for streaming log data from Microsoft Azure Event Hubs to your instance.

    Before you begin

    Role required: evt_mgmt_admin

    About this task

    You can set system parameters for reading log data that determine the actions that the system performs on log data arriving on the MID Server. For example, you can set the time zone to use if a log lacks a timestamp. If no advanced settings are configured, the system uses the default values.

    Procedure

    1. Navigate to All > Health Log Analytics > Data Input > Data Inputs.
    2. Open a Microsoft Azure Event Hubs data input record from the Data Inputs table.
      Note:
      If the HLA 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.
    3. Select Advanced and then select the Advanced tab.
    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: In the Streaming Sources related list, verify that this data input is streaming log data from all relevant endpoint devices.
      For more information about streaming sources, see Identify and resolve a log streaming issue in Health Log Analytics.
    6. Select Save.
      Health Log Analytics adds the data input record to the Data Inputs table.
    7. 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.
    8. Select Publish to publish the data input to the MID Server.
