Hi Guys,
I have issu with data report from memory utilization on chart line mode like this picture

Why doesn't the data from December 9 to December 19 appear in the report?
If we look at the condition of the servers that are included in the report through the perfstack analyst, the servers are running normally from December 9 to December 19.

but in the data report on that date it doesn't appear.
Please help anyone with a similar experience
