For all statistics not automatically collected as a part of perpetual monitoring, you can manually create a monitor to gather statistics of XCOPY latency on a particular metro node virtual volume.
You create a monitor and configure a file sink so that the stats for the particular fe-lu (metro node virtual volume) will be collected in the configured file.
The following example shows how to create a monitor to collect the fe-lu.xcopy-avg-lat statistics for a give volume (VAAI_Vol1_Device_vol) in a file (/tmp/monitors/director-1-1-A-fe-lu-avg-lat):
