All performance pages allows you to print the page and export to Excel, By default, the <span style="font-weight: bold">Export To Excel</span> 
icon is the export traffic number in raw digit format. You can export the same unit number for the traffic 
data, such as GB/Gb/MB/Mb/KB/Kb/B/b, For example; If you want to display the traffic numbers in GB, 
you need to modify the <span style="font-weight: bold">server.properties</span> fileto set <span style="font-weight: bold">export.unitless</span>=false and <span style="font-weight: bold">export.unit=GB</span>.
