The Web Reports feature for the Web Application - View Systems tool contains two types of data reports
These reports query collected data on demand, that is, at the time the report is requested. This information is not saved to disk as the report and the time period that the report will cover is typically limited, e.g. 'Yesterday', 'Today'.
These reports run on a schedule and the resulting report 'snapshots' are saved to disk as HTML files for later viewing. These reports are configured by Administrators.
Snapshot Reports are not supported when using split Prognosis deployment, ie. Web Application is deployed separately from the Management Server. See Split Deployment of the Web Application Server and Management Server
