The "Roll-Up By" feature allows you to combine time series. For example, if you click the "All" checkbox, then all the Time series will be combined and the Chart will show the total number of queries, as a function of time, that your domain received over your selected time frame. If you're following along, please unselect the "All" checkbox to show all the Time series.
You can also combine multiple time series together by selecting the dimensions you want to see together. For example: select only the "Record Type" and "Record Name" checkboxes. Now all the record types and record names will be combined, and the remaining Time series will only have location dimensions. Effectively, you are now seeing the queries received at each of the top five DNS Made Easy name servers locations. The legend at the bottom of the Chart will show the series only by location.
This is the same view you will remember from the initial download. That's because this view is quick to load and provides a general overview of your domain's query traffic.
Suppose that we want to see which records (Record Names) were queried at each location. Simply unselect the "Record Type" checkbox so that the roll-up is only by record type. Unselecting the "Record Type" checkbox requires Real-time stats to download more detailed data. Depending on the number of records composing your domain, this download can take 10 to 20 seconds or more. Once the data is loaded, the Chart will display the Time series for locations and record names.
We've seen how to display the total queries for your domain, the queries at each location, and the queries for record names at each location. Suppose that we would like to display the queries for your domain's record names. If we select the "Location" checkbox in the "Roll-Up By" section, what remains in the Chart are the time series for each record name in your domain.
