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).
