Bhuvan,
You are correct that libmemstat and derived tools currently rely on features
present in the FreeBSD kernel. The library provides a general monitoring
abstraction over a set of specific kernel memory allocators -- specifically,
the FreeBSD malloc(9) and uma(9) allocators. It is relatively straight
forward to implement that abstraction for other memory allocators, such as
user space allocators or kernel allocators from other platforms, but that work
has not been done (as far as I know). I'm not aware of specific monitoring
tools for the Linux operating system that are able to perform this type of
profiling/monitoring, although I presume some sort of kernel memory profiling
tool does exist.
Thanks,
Robert N M Watson
