Identifying Busiest LUNs

To identify the LUNs that generate the most traffic on the NetApp Filer, use the ReadByteRate and WriteByteRate parameters of the SEN_NA_LUN class. NetApp Filers KM for PATROL offers you two methods to visually represent a LUN traffic.

Create a multi-parameter graph with the ReadByteRate and WriteByteRate parameters of the LUN objects you are suspecting

1.In the console, double-click the ReadByteRate parameter of the LUN you are interested in. A graph is instantly displayed in the graph pane.
