Does vFoglight provide min/max data points for Network I/O of Virtual Machines
vFoglight does not collect (and we don't think the VC offers) min/max data points. So it gets current network usage at the time the data is collected. But as data is rolled up, it does keep average and min/max values for the rolled up metrics.
So for any given VM, navigating to Dashboards > Configuration > Data > VMware > Virtual Machines > VM_name > Network > Interfaces > Host Interface > Send Rate and Recieve Rate metric histories will show the min/max of the rolled up data. But data that has not yet been rolled up will only show the usage that was current when the data was collected.
