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
