Performing Health Checks on MRS Cluster Nodes

If the running status of a host is not Normal, you can perform health checks on the host to check whether some basic functions are abnormal. During routine O&M, you can perform host health checks to ensure that the configuration parameters and monitoring of each role instance on the host are normal and can run stably for a long time.
