      Input Parameters

      EMR (Node) supports querying monitoring data based on the following five combinations of dimensions. The values for the input parameters are as follows:
      1. To query the metric monitoring data of Server - CPU, use the following input parameters: &Namespace=QCE/TXMR_NODE &Instances.N.Dimensions.0.Name=id4nodecpu &Instances.N.Dimensions.0.Value=EMR instance ID &Instances.N.Dimensions.1.Name=host4nodecpu &Instances.N.Dimensions.1.Value=Specific node IP in the EMR instance
      2. To query the metric monitoring data of Server - Memory, use the following input parameters: &Namespace=QCE/TXMR_NODE &Instances.N.Dimensions.0.Name=id4nodememory &Instances.N.Dimensions.0.Value=EMR instance ID &Instances.N.Dimensions.1.Name=host4nodememory &Instances.N.Dimensions.1.Value=Specific node IP in the EMR instance
      3. To query the metric monitoring data of Server - Network, use the following input parameters: &Namespace=QCE/TXMR_NODE &Instances.N.Dimensions.0.Name=id4nodenetwork &Instances.N.Dimensions.0.Value=EMR instance ID &Instances.N.Dimensions.1.Name=host4nodenetwork &Instances.N.Dimensions.1.Value=Specific node IP in the EMR instance
      4. To query the metric monitoring data of Server - Filehandle, use the following input parameters: &Namespace=QCE/TXMR_NODE &Instances.N.Dimensions.0.Name=id4nodefilehandle &Instances.N.Dimensions.0.Value=EMR instance ID &Instances.N.Dimensions.1.Name=host4nodefilehandle &Instances.N.Dimensions.1.Value=Specific node IP in the EMR instance
      5. To query the metric monitoring data of Server - Process, use the following input parameters: &Namespace=QCE/TXMR_NODE &Instances.N.Dimensions.0.Name= id4nodeprocess &Instances.N.Dimensions.0.Value=EMR instance ID &Instances.N.Dimensions.1.Name=host4nodeprocess &Instances.N.Dimensions.1.Value=Specific node IP in the EMR instance
