A log is an automatically generated, time-stamped file that provides an audit trail for system events on the firewall or network traffic events that the firewall monitors. Log entries contain artifacts, which are properties, activities, or behaviors associated with the logged event, such as the application type or the IP address of an attacker. Each log type records information for a separate event type. For example, the firewall generates a Threat log to record traffic that matches a spyware, vulnerability, or malware signature or a DoS attack that matches the thresholds configured for a port scan or host sweep activity on the firewall.

The Cloud NGFW can send traffic, threat, and decryption logs to an Azure Log Analytics Workspace that you will create in the Azure portal. The Log Analytics Workspace is associated with a workspace ID, primary Key, and a secondary key, which is retrieved through the logging API by the control plane.
