Is this for a single node or multiple nodes? Does it have to be a table or you OK with a chart? If a chart is OK with you, you can simply click on the charting dashboard resources (for the legacy ones or on the export button for the newer chart resources), adjust the chart width, relative time frame and sampling interval (5 minutes) and copy the URL. You can then use the Reports Schedule Manager to schedule this URL. You can append &printable=true to the URL to make it cleaner in the email
