When I look at
https://github.com/jenkinsci/extras-memory-monitor/blob/master/src/main/java/org/jvnet/hudson/MemoryMonitor.java
,
it seems to indicate that the memory monitor inside Jenkins is unable to
find /proc/meminfo and cannot find a suitable `top` command.  It decides
that NONSTOP_KERNEL is not Windows, not AIX, and not Solaris.

If you can't install a workable version of the "top" command, then you may
need to submit a pull request to add support for NONSTOP.

Thanks,
Mark Waite
