NAME
       pcp-slabinfo - Report statistics for kernel slab allocator

SYNOPSIS
       pcp [pcp options] slabinfo [-a archive] [-s samples] [-Z timezone]

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.

OPTIONS
       -a file, --archive=file
              Fetch /proc/slabinfo for a specified archive file

       -s count, --samples=count
              Get the slabinfo statistics for specified number of samples
              count

       -V, --version
              Display version number and exit.

       -z, --hostzone
              Use the local timezone of the host that is the source of the
              performance metrics, as identified by either the -h or the -a
              options.  The default is to use the timezone of the local host.

       -Z timezone, --timezone=timezone
              Use timezone for the date and time.  Timezone is in the format
              of the environment variable TZ as described in environ(7).

       -?, --help
              Display usage message and exit.

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

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).
