Can you please guide us where we can get the attached table for customer usage that represent the below graph.
This is a screenshot from Perfstack. You can learn more here support.solarwinds.com/.../SolarWinds-Performance-Analysis-PerfStack
Are there any APIs by which we can show this graph on the external system ? If yes then can you please send me the URL ?
Google Solarwinds Orion SDK and you will find information about the API. The stats you are looking for are available to query from an external tool if you need to.
I believe the data for this graph will be in Orion.NPM.InterfaceTraffic entity, accessible via Solarwinds API. You can check with SWQL Studio too.
