I have purchased multiple enterprise licenses for my clients. PRTG is just a good tool we recommended.
But why after so many years the reporting functions still s*ck? Here we have 2000 sensors and only 200 devices. I dont think any one is more interested in report per sensor than report per device.
If I can generate reports per device, I can show SLA uptimes. Now in reality nobody and especially no executive will be interested in sensors reports, but they do if you tell them the webservers have a ??% uptime over x time period.
Its end of the year, so many companies like us need present some reports about 2013. Well PRTG fail miserably in this regard, while it should have all the data to do so.
