Amazon ECS - Show # of Tasks Per Service


I am using the cloudwatch data source, and am trying to display the # of tasks for a given service. Amazon does not issue metrics concerning task count, but they recommend doing a SampleCount on CPUUtilization metric in CloudWatch as a way to see that figure.

In Grafana, I can successfully get the sample count on CPUUtilization, which I believe is returning me the correct figure. I cannot however, get the graph panel to display the unit as any unit other than percent.

Changes to the UI to select another unit type simply defaults back to Percentage. Similarly, updates to the JSON of the panel also revert back to percent.

What am I doing wrong?
