We do not have a scheduled report with only numerical values. However you can create a custom report which will give only numerical report.
In reports tab -> Custom Report -> Create Custom report -> Select the monitortypes (server monitor in this case -> Attributes -> Monitors -> Period.
You will get a report with numerical values. You can export this report as a PDF.
I understand that it will be easier to schedule this report or have it along with the regular report. We will see how best we can support this. Thanks for raising your concerns.
