If you are not seeing any information in the Fastvue TMG Reporter Dashboard, go to Settings | Sources.
Make sure your source(es) show records being imported. If there are records being imported and if the source has only recently been added, wait for a few more minutes.
The Dashboard will show information once it has imported and analyzed the first batch of data. Depending on how much data you have being logged, this may take a few minutes.
If your source does not show any records being imported, see the article No records are being imported into a Source
