Enabling the OLC Function

Context

To control the monitored protocol packets and tasks in time in case of CPU overload, the OLC function is enabled globally by default. You can enable the OLC function for a specified protocol or task. In addition, the OLC alarm function is enabled by default. When the CPU usage reaches the OLC start threshold or falls below the OLC stop threshold, an alarm is generated.
