Port liveness detection is port detection initiated from the agent for an application service. For example, a service exposes port 12200 and can be pinged under normal conditions. However, if the service is down, the port cannot be accessed. Port detection can periodically check whether an application service is alive to ensure that the application can provide external services. This topic describes how to customize monitored ports when application details are displayed in a visualized manner.
