Firewall logs to Cortex Data Lake log buffering

HowsThisWork — Thu, 18 Apr 2024 19:33:35 GMT

Hello,

For firewalls managed with Panorama there's a setting in Panorama "Buffered Log Forwarding from Device" which tells the firewall to buffer it's log in the case of loss of connectivity with Panorama.

Does anyone know if there is an equivalent feature when sending logs from firewalls to Cortex Data Lake? I'm not seeing anything in documentation that mentions the expected behavior. Or anyone familiar with how the firewall handles logs when it loses connectivity to Cortex Data Lake? It seems like I'm seeing some intermittent lost logs between the local firewall and Cortex Data Lake.

Thank you.

Hi HowsThisWork,

After the loss of the connection between FW and CDL, FW logs will be queued and sent once the connection is restored. If queue is full before connection establishment, some logs will be lost. You may use the below CLI to check that:

> show counter global filter delta yes | match queue_full

Log collection can be monitored using the Incoming Log Rate or Log Forwarding Status dashboards in the Cortex Data Lake.
