Configure a Cribl data input in Health Log Analytics

Configure a dedicated Cribl data input to enable Health Log Analytics to process Cribl log messages streaming into your ServiceNow instance.

Avant de commencer

• Verify that a MID Server is installed and configured with the Log Ingestion capability enabled. For more information, see MID Server system requirements.

  

  Important :

  Health Log Analytics does not support IPv6. To work with the application, configure the MID Server to IPv4.
• Unless the MID Server and external clients are on the same network, the MID Server must have a public IP address. This is required when its IP is exposed through network address translation (NAT), a load balancer, or a similar device. The public IP address enables external clients, such as Filebeat agents located outside its network, to reach the MID Server. Private IP addresses are not routable over the internet. Without a public IP, external clients cannot connect to the MID Server even if they are configured with its 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. If the MID Server and external clients are on the same network, connections can be made using the private IP address.

Pourquoi et quand exécuter cette tâche

If your organization uses Cribl for filtering and routing large volumes of log data from various sources, the log format Health Log Analytics receives is distinct from other types. The Cribl data input enables HLA to detect and separate transport headers from inner log messages in this format, forwarding only the inner message to the source type structure for processing.
