NAME ^

OpenVZ::BC - Perl access to OpenVZ Beancounter Data

SYNOPSIS ^

  use OpenVZ::BC;
  my $bc = OpenVZ::BC->new;
  my $resources = $bc->hash;

DESCRIPTION ^

Gives Perl access to OpenVZ beancounter data. This data is typically stored in /proc/user_beancounters or /proc/bc/resources. By default, we use /proc/bc/resources, but this can be overridden as described below.

INTERFACE ^

new

  my $bc = OpenVZ::BC->new;
  
  my $bc = OpenVZ::BC->new(
    bc_file => '/proc/user_beancounters',
  );

Creates the new OpenVZ::BC object.

bc_file [optional]

If you specify bc_file here, it will override the default location. Currently that default location is /proc/bc/resources. Specified here, it will define the default location of this file for any methods used below.

hash

  my $resources = $bc->hash;
  
  my $resources = $bc->hash(
    bc_file => '/proc/user_beancounters',
  );
  
  my $resources = OpenVZ::BC->hash;
  
  my $resources = OpenVZ::BC->hash(
    bc_file => '/proc/user_beancounters',
  );

This returns a hashref containing the beancounter data from the default or specified file. If accessed via the $bc object, it will use the default specified in that object. If you use it via the class directly, it will use the class default.

bc_file [optional]

If you specify bc_file here, it will override the default location of either the $bc object and/or the class.

TODO ^

Provide access to the /proc/bc/<VPSID>/resources files to access a single VPS beancounters instead of reading the full server's beancounters. This would involve adding new methods. Patches are welcome.
