Tip: Display the Sum of a Metric Across Multiple Data Sources

Q: Can I display the sum of a metric across multiple data sources?
A: Yes. Visualization in EDM includes a sum across data sources feature. When you create a chart, click the Sum Across Data Sources checkbox. Add the chart to a template, then create a report using that template and assign multiple data sources to the report. When the report is displayed, the target metric(s) will be summed for all of the data sources selected in which it appears.

In the example below, the metric IIS Log Requests per Second is summed across ten data sources on the left, and shown per data source on the right.
