Remarks

The working set that Task Manager shows counts memory shared with other processes (the JVM's mapped class data, system libraries) and, on Windows, leaves out heap the JVM committed and has not touched. What the machine really gives up for a server is its private memory, so that is what the RAM card shows, and what the history keeps.

Windows: PrivateMemorySize64, the committed private bytes. Linux: the private pages in smaps_rollup. Elsewhere, and whenever that cannot be read, the working set: a number a little too high is better than none.

ZGC is the exception: on Windows its heap is mapped in a way private bytes do not count, so the reading is far too low. The caller picks the working set for it (see MemoryReadout).
