Log Forwarding Options

By default, each firewall stores its log files locally. To use Panorama for centralized log monitoring and report generation, you must Configure Log Forwarding to Panorama. Panorama supports forwarding logs to either a Log Collector, the Logging Service, or both in parallel. You can also use external services for archiving, notification, or analysis by forwarding logs to the services directly from the firewalls or from Panorama. External services include the syslog servers, email servers, SNMP trap servers, or HTTP-based services. In addition to forwarding firewall logs, you can forward the logs that the Panorama management server and Log Collectors generate. The Panorama management server, Log Collector, or firewall that forwards the logs converts them to a format that is appropriate for the destination (syslog message, email notification, SNMP trap, or HTTP payload).
Palo Alto Networks firewalls and Panorama support the following log forwarding options. Before choosing an option, consider the logging capacities of your Panorama Models and Determine Panorama Log Storage Requirements.
  • Forward logs from firewalls to Panorama and from Panorama to external services—This configuration is best for deployments in which the connections between firewalls and external services have insufficient bandwidth to sustain the logging rate, which is often the case when the connections are remote. This configuration improves firewall performance by offloading some processing to Panorama.
    You can configure each Collector Group to forward logs to different destinations.

  • Forward logs from firewalls to Panorama and to external services in parallel—In this configuration, both Panorama and the external services are endpoints of separate log forwarding flows; the firewalls don’t rely on Panorama to forward logs to external services. This configuration is best for deployments in which the connections between firewalls and external services have sufficient bandwidth to sustain the logging rate, which is often the case when the connections are local.
