Is there a CPAN Perl module to search for shared / used / free memory on a host (without executing a command line through a call to system ())?

Question

Is there a Perl CPAN module that provides shared / used / free memory (e.g. vmstat ) on the host without executing a command line via a system() call to retrieve information?

Ideally, it should be cross-platform (Linux and Solaris), although please also provide Linux or Solaris.

Answer 1

It looks like Sys::MemInfo is what I need.

It is implemented in XS using <sys/sysinfo.h> for Linux and <sys/stat.h> / <sys/swap.h> for Solaris.

Answer 2

Try Sys :: Statistics :: Linux for Linux.
