Installed NPM B3 on a test server for a week now, really like the new features such as QoE, Heat Maps, Web Alerting, Agent for Window server, Storage Capacity Forecast, etc.
From Capacity Forecast Chart, it looks the linear regression method (Ordinary least squares?) is used for Capacity Forecast. I did created some MSSQL reports to do the similar prediction using same method. (https://thwack.solarwinds.com/docs/DOC-171060, https://thwack.solarwinds.com/docs/DOC-171023)
But one issue for this method is that not all data are linear, this method only works well if data are close linear. I would like to suggest that the linear correlation coefficient (0<=p<=1) should be considered and displayed to show how accurate the predicated data are. The” Top xx Capacity Problems” should only show volumes which p is close to 1, say p>0.75.
Thanks
