Hi All:
I've notice our DRE cache has dropped from days down to 4hrs hours in the data center. Before adding another appliance to the farm, I would like to know if there is a way to see what is eating up the cache? For example, is it a specific site using more DRE cache than others or a particular traffic flow eating up the majority. What kind of visability does the WAAS provide into this?
Thanks,
Patrick

Hi Patrick,
You can get separate statistics for each of the DRE peers using the command "WAE# show statistics peer dre". With this command, you should be able to see which peer is consuming most of the disk space and the amount of connections each of them have.
I hope this helps

Perfect. That is exactly what I needed. I have it narrow down to flows between two appliances. Thanks!
