Can you elaborate a bit further about what I should worry about in terms of swap activity? Anything related to SWAP I could find in the da…

Thanks for the images - I would mostly monitor the top one, the pages per second. If you see sustained activity then you need more memory. Short spikes like we see in your picture are fine.
