Here is a good example of memory variation across a medium term.
There is no swap usage in this case, but it does show well the metric to watch is ‘available’
Use case dictates how shared and buff/cache will vary. In this case large tmpfs's are in use and show under ‘shared’. Large scp transfers bounced through, and they show up it buff/cache. The seemingly low ‘free’ stat isn't so indicative of much. I didn't catch it here, but my assumption is low ‘available’ is what would trigger some swap.
