You don't get a lot of response to your question since it isn't clear what you want to know.
In the Ultimaker printers you don't have to calibrate the filament flow since the variation between printers is very small. Perhaps you think there is a problem with the filament flow and you are asking for a way to verify this?
If yes, then I don't know 'the best way', but there are a few maintenance tasks you can do:
If all this didn't help, then on the UM2(+) you might have a problem with the hotend insulator being degraded, this happens sooner when you print at temperatures > 250C. These hot end isolator couplers are sold all over the internet

In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications

If yes, then I don't know 'the best way', but there are a few maintenance tasks you can do:
- Clean the nozzle: https://ultimaker.com/en/resources/19510-how-to-apply-atomic-method
- Verify the feeder tension is set to the middle of the allowed range (there is a small screw on top of the feeder)
- When you had a lot of grinding recently, perhaps clean the feeder insides: https://ultimaker.com/en/resources/50688-clean-the-feeder
- Retighten the hotend insulator: https://ultimaker.com/en/resources/50677-retighten-the-hot-end-isolator
