Pourquoi et quand exécuter cette tâche

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.

For information about how to change settings that were configured when the data input was created, such as adding a new path or changing the data input's MID Server destination or port, see Modify a data input configuration in Health Log Analytics.

Procédure

1. Navigate to All > Health Log Analytics > Data Input > Data Inputs.
2. Open a Rsyslog, Splunk, or TCP data input record from the Data Inputs table.
   The data input configuration displays.

   Remarque :

   The number of log sources that the data input has created is shown in the Sources count field. For more information about data input sources, see Log data auto-mapping and mapping in Health Log Analytics.

   Remarque :

   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.
4. On the form, fill in the fields.
   For a description of the fields, see Rsyslog, Filebeat, or Winlogbeat data input configuration fields.
5. Facultatif : 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 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. This field displays only when a streaming error has occurred.

     Resolve the issue, select Save if you modified the configuration, and then select Test connection to test the connection again.

     Remarque :

     You can only publish the data input configuration when the connection is created successfully.

   Remarque :

   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.
