Description
When opening the grafana performance details tab for any host on the page "Hosts", the displays for the "Disk IOPS" and the "Throughput by Disk" are emtpy. When clicking on the red exclamation mark in the upper left corner of one of the displays, a JSON error is displayed.
Here is an example of the error message:
error:Object

];
