Question 14

During a high-availability planning session for an on-premises Broker VM deployment, an architect considers deploying multiple Broker VMs behind a load balancer to handle syslog collection from thousands of network devices. What is a critical architectural limitation or consideration when placing Broker VMs behind a load balancer for syslog collection?

Accepted Answer

Load balancing TCP or UDP syslog streams requires careful session persistence and source IP retention to ensure parser context is maintained. When configuring UDP syslog load balancing, statefulness and IP persistence must be carefully managed, and TCP syslog requires persistent connections or proper session handling to prevent log interleaving and parsing corruption.

Answer

Broker VMs cannot accept syslog data if they are registered to the same XSIAM tenant token
