Configuring a Monitoring History Report


On MRS Manager, the nodes where roles are deployed in a cluster can be classified into management nodes, control nodes, and data nodes. Change trends of key host monitoring indicators on each type of nodes can be calculated and displayed as curve charts in reports based on user-defined periods. If a host belongs to multiple types of nodes, the indicator statistics will be collected several times.

You can view, customize, and export node monitoring indicator reports on MRS Manager.
