Which of the following is a valid CN-MGMT metric to auto scale CN-Series firewall?

The metric that is valid for auto-scaling the CN-Series firewall is pandataplaneslots. This metric is specifically designed to monitor the utilization of data plane slots, which are critical for managing traffic and ensuring the efficient performance of the firewall. By using this metric to auto-scale, organizations can effectively manage loads based on how many data plane slots are currently being utilized, thus optimizing resource allocation and enhancing performance under variable traffic conditions.

In contrast, metrics like management plane CPU utilization percentage, throughput, and packet rate are more aligned with assessing different aspects of performance. While they provide valuable information about the overall operational health of the firewall, they do not directly correspond to the scaling requirements of the data plane, which is crucial for maintaining optimal traffic handling capabilities. Therefore, focusing on the number of available data plane slots for scaling purposes allows for more effective resource management tailored to workloads specific to network traffic demands.
