NAME

       pcp-slabinfo - Report statistics for kernel slab allocator statistics

SYNOPSIS

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

DESCRIPTION

       The pcp-slabinfo command is used for viewing different stats related to  slab.   It  helps
       users  analyze useful information related to the slab allocator.  The information includes
       the total number of objects that are currently active, allocated objects, pages per  slab,
       etc.  By default, pcp-slabinfo reports live data for the local host.

       The statistics shown are as follows:

       HEADER         DESCRIPTION
       ───────────────────────────────────────────────────────────────────────────────────────────
       active_objs    The number of objects that are currently active (i.e., in use)
       num_objs       The total number of allocated objects (i.e. objects that are both in use
                      and not in use).
       objsize        The size of objects in this slab, in bytes.
       objperslab     The number of objects stored in each slab.
       pagesperslab   The number of pages allocated for each slab
       active_slabs   The number of active slabs.
       num_slabs      The total number of slabs.

NOTES

       pcp-slabinfo collects information from /proc/slabinfo 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).
