Attached patch backports an upstream feature to add swap usage to the memory plugin of munin. The original upstream patch can be found at: https://github.com/munin-monitoring/munin/commit/0ceb8560ad5967862a4dfa0f6695f2763ef00599
Hopefully this can be added after the ports tree is unlocked again. Thanks, Frank
