Unable to monitor Virtual SAN read cache layer from the vSphere Web Client.
Hi, please check out http://blogs.vmware.com/vsphere/files/2014/08/Monitoring-with-VSAN-Observer-v1.2.pdf
It is from 2014 but still valid 😉
BTW i hope vmware engineering will integrate some of the observer stuff in the web client at some point in the future.
Best,
Joerg
