DESCRIPTION

13       The pcp-slabinfo command is used for viewing different stats related to
14       slab.   It  helps  users analyze useful information related to the slab
15       allocator.  The information includes the total number of  objects  that
16       are  currently  active, allocated objects, pages per slab, etc.  By de‐
17       fault, pcp-slabinfo reports live data for the local host.
18
19       The statistics shown are as follows:

PCP ENVIRONMENT

57       Environment variables with the prefix PCP_ are used to parameterize the
58       file and directory names used by PCP. On each  installation,  the  file
59       /etc/pcp.conf  contains  the  local  values  for  these  variables. The
60       $PCP_CONF variable may be used to specify an alternative  configuration
61       file, as described in pcp.conf(5).
62
63       For environment variables affecting PCP tools, see pmGetOptions(3).
