To select multiple services for your report in the statistics section of your ArcGIS Server Manager, can be really slow and painful. For each checkbox selected you have to wait until Manager have extracted the data and showing it on the graph. Some kind of batch selection method would be nice here, for example ctrl+click to select/unselect all services in current service folder. Another way of solving this would be to expand the "Usage Reports Configuration" in the ArcGIS Server Administration Directory with a checkbox to set automatic update on the graph to true/false, and if set to false, users would see a "update graph"-button on the statistics web page in AGS Manager.
