Sys::Statistics::Linux::MemStats (3pm)

    use Sys::Statistics::Linux::MemStats;

    my $lxs  = Sys::Statistics::Linux::MemStats->new;
    my $stat = $lxs->get;

Sys::Statistics::Linux::MemStats gathers memory statistics from the virtual /proc filesystem (procfs).

For more information read the documentation of the front-end module Sys::Statistics::Linux.

Generated by /proc/meminfo.

memused - Total size of used memory in kilobytes. memfree - Total size of free memory in kilobytes. memusedper - Total size of used memory in percent. memtotal - Total size of memory in kilobytes. buffers - Total size of buffers used from memory in kilobytes. cached - Total size of cached memory in kilobytes. realfree - Total size of memory is real free (memfree + buffers + cached). realfreeper - Total size of memory is real free in percent of total memory. swapused - Total size of swap space is used is kilobytes. swapfree - Total size of swap space is free in kilobytes. swapusedper - Total size of swap space is used in percent. swaptotal - Total size of swap space in kilobytes. swapcached - Memory that once was swapped out, is swapped back in but still also is in the swapfile. active - Memory that has been used more recently and usually not reclaimed unless absolutely necessary. inactive - Memory which has been less recently used and is more eligible to be reclaimed for other purposes. On earlier kernels (2.4) Inact_dirty + Inact_laundry + Inact_clean.

The following statistics are only available by kernels from 2.6.

slab - Total size of memory in kilobytes that used by kernel for data structure allocations. dirty - Total size of memory pages in kilobytes that waits to be written back to disk. mapped - Total size of memory in kilbytes that is mapped by devices or libraries with mmap. writeback - Total size of memory that was written back to disk. committed_as - The amount of memory presently allocated on the system.

The following statistic is only available by kernels from 2.6.9.

commitlimit - Total amount of memory currently available to be allocated on the system.

\fInew()\fP

Call \*(C`new()\*(C' to create a new object.

my $lxs = Sys::Statistics::Linux::MemStats->new;

It's possible to set the path to the proc filesystem.

Sys::Statistics::Linux::MemStats->new( files => { # This is the default path => '/proc', meminfo => 'meminfo', } );

\fIget()\fP

Call \*(C`get()\*(C' to get the statistics. \*(C`get()\*(C' returns the statistics as a hash reference.

my $stat = $lxs->get;

No exports.
