Which message ID should an NSX administrator use to filter syslog events related to NSX host preparation?

The correct choice for filtering syslog events specifically related to NSX host preparation is FABRIC. This message ID encompasses events that pertain to the NSX infrastructure, including the preparation of hosts within that fabric. Host preparation involves the configuration of the NSX virtual networking components on physical hosts, ensuring they are ready to manage and forward network traffic according to NSX policies.

By utilizing the FABRIC message ID, administrators can effectively streamline their monitoring and management processes, as it allows for focused insights into the status and health of the host environments that NSX operates on. This is particularly beneficial during deployments or when making changes to the network architecture, as any issues in host preparation will be logged under this specific category.

The other options do not specifically correlate with host preparation. SYSTEM is more generic and encompasses a variety of overarching system logs; GROUPING relates to event categorization within NSX, typically for traffic flows or policies; while MONITORING involves collected data about the overall system performance and health, which does not isolate host preparation events. Hence, using FABRIC for syslog filtering ensures precise tracking of relevant events.
