Some validation of the output
Screenshot 2026-01-07 at 16 10 27

As is visible on the screenshot process with PID 43 and 90 really used no swap memory. And process with PID 640 used 1272 kB of swap memory (which is 1302528 bytes) and it matches what is shown in Kibana.

To make sure nothing breaks on other platforms I've run a test on macos (it is working fine, swap field is null on other than Linux platforms)

Closing this one as it was decided not to backport the original PR (at least until there is a specific request to support this in specific version)
