The component identifier of the component to be monitored may be specifically understood as identifying information capable of uniquely determining the component to be monitored, which may be a process ID of an operating process of an operating system corresponding to the component to be monitored, a service name of a service provided by the component to be monitored, and the like, which is not limited in this embodiment.
For example, after the components to be monitored in the cluster are started, the components identification of the components to be monitored can be actively sent to the central component in the cluster; the central component receives and records the component identification sent by the component to be monitored and actively sends the component identification to the main monitoring tool, or the main monitoring tool sends an identification inquiry request to the central component, and the central component sends the component identification of the component to be monitored to the main monitoring tool after receiving the identification inquiry request sent by the main monitoring tool.
