Manager Agent is an agent that is used by E-MapReduce (EMR) StarRocks Manager to connect to a StarRocks instance. By default, Manager Agent is deployed in frontend nodes (FEs). If the loads on your FEs are high or you have high requirements on the stability of StarRocks Manager, you can activate Manager Agent separately.
