How can you change the behavior of log storage when the allowed disk space is full?

The option regarding setting "diskfull nolog" in the local log settings is correct because it directly impacts the logging behavior when disk space reaches its limit. By configuring the device to "diskfull nolog," the system is instructed to stop logging new entries once the disk space is full. This way, it prevents logs from consuming additional resources, which could lead to system instability or potential data loss. This setting is particularly useful in environments where there is limited disk space, as it allows administrators to take control over log management and avoid unexpected issues.

The other options would not effectively manage conditions of full disk space in the way required. For instance, adjusting system memory settings does not influence disk storage behavior. Increasing disk space capacity might provide a temporary solution, but it doesn’t address the immediate concern of managing logs when the predefined disk quota is reached. Disabling log storage during high usage might hinder critical logging functions, leading to potential oversight of important events. Therefore, the approach of setting "diskfull nolog" is a targeted and effective way to manage log behavior under constrained disk conditions.
