I've been trying to figure out a way to get performance metrics (IOPS, Read RT, Write RT, etc) for individual volumes (devs). Pulling this through the gui is pretty painful, but I can't seem to find it a way to do it through the api either.
I'm using the PyU4V library by Paul Martin (great btw) and also looking at the RESTclient to navigate through the objects. The particular array I'm working with is a VMAX3 running 126.96.36.199, but we have quite a few other VMAXes running different code levels too.
Indeed Dynamox! to be fair I have got the request from a number of customers, and we are looking at its feasibility at present but we can't commit to it going ahead yet without further testing, if that changes I will let you know.
