IOPs reading zero after vCenter reboot
VxRail Manager is now showing zero IOPs for the cluster after rebooting vcenter. CPU usage and Memory usage are showing successfully, however Storage IOPs is still flat. We verified that we can see IOPs in vcenter and we have also tried to reboot the vxrail manager appliance.

For this PoC we took a node offline for a test and it appears that it caused the IOPs to no longer show. After bringing the 4th node back online we were able to see output again.

We tried the script to see the latency and it does not look to be the problem here. Our output was:
real 0m0.874s
user 0m0.153s
sys 0m0.025s
