NAME

       pcp-buddyinfo - Report statistics for buddy algorithm shown in cat /proc/buddyinfo

SYNOPSIS

       pcp  [pcp options] buddyinfo [-s samples] [-a archive] [-Z --timezone] [-z --hostzone] [-V
       Version]

DESCRIPTION

       The pcp-buddyinfo command is used for viewing different stats  related  to  buddyinfo.  It
       helps  users  analyze  useful  information related to the buddy algorithm. The information
       includes the total number of zones that are currently active, order pages etc. By default,
       pcp-buddyinfo reports live data for the local host.

       The statistics shown are as follows:

       HEADER          DESCRIPTION
       _               _
       Normal          zones available
       Nodes           available nodes
       Order0          available pages of order 0
       Order1          available pages of order 1
       Order2          available pages of order 2
       Order3          available pages of order 3
       Order4          available pages of order 4
       Order5          available pages of order 5
       Order6          available pages of order 6
       Order7          available pages of order 7
       Order8          available pages of order 8
       Order9          available pages of order 9
       Order10         available pages of order 10

       Each  column  represents  the number of pages of a certain order (a certain size) that are
       available at any given time. For example, for zone DMA (direct memory access),  there  are
       90  of 2^(0*PAGE_SIZE) chunks of memory. Similarly, there are 6 of 2^(1*PAGE_SIZE) chunks,
       and 2 of 2^(2*PAGE_SIZE) chunks of memory available.

       The DMA row references the first 16 MB on a system, the HighMem row references all  memory
       greater than 4 GB on a system, and the Normal row references all memory in between.

NOTES

       pcp-buddyinfo  collects  information  from /proc/buddyinfo and aims to be command-line and
       output compatible with it.

PCP ENVIRONMENT

       Environment variables with the prefix PCP_ are used to parameterize the file and directory
       names  used by PCP. On each installation, the file /etc/pcp.conf contains the local values
       for these variables. The  $PCP_CONF  variable  may  be  used  to  specify  an  alternative
       configuration file, as described in pcp.conf(5).

       For environment variables affecting PCP tools, see pmGetOptions(3).
