Hi darraghos,
digging into each and every performance counter is not what OCUM 7.x is designed for.
If you need to dig deeper, I suggest to have a look at Grafana - an open source project to visualize performance data.
One of my colleagues offers an all-in-one vApp with Grafite, Grafana and an automated way to install the NetApp Managability SDK (NMSDK) and Harvest (the ONTAP performance collector) with pre-defined dashboards to directly get you going.
Please have alook here:

You can also set up a server yourself with Grafite and Grafana. The only things you need from NetApp then are:
Harvest:

NMSDK:
https://mysupport.netapp.com/NOW/cgi-bin/software/?product=NetApp+Manageability+SDK&platform=All+Platforms
For all questions on Harvest please consult the NetApp Community as it's not a software that's covered under NetApp support agreement.
regards, Niels
