Dear all,
I have a Local zone , where users feel that performance is not good.
Is it wise to collect the inputs from the local zone rather than taking from the global zone.
And also Can I tune from Global zone , so that it will reflect in local zone.

NAME
pmdbg - translate Performance Co-Pilot debug control flags
SYNOPSIS
pmdbg code ...
pmdbg -l
DESCRIPTION
The components of the Performance Co-Pilot (PCP) use a global vector of bit-fields to control diagnostic and debug output.
pmdbg with a -l argument prints out the mnemonic and decimal values of all the bit-fields in the debug control vector.
In the alternative usage, the code arguments are values for the debug vector, and the bit-fields that are enabled by each of these values
is listed.
Each code may be an integer, a hexadecimal value or a hexadecimal value prefixed by either ``0x'' or ``0X''.
Most applications using the facilities of the PCP support a -DN command-line syntax to enable debug control. pmdbg is designed to help
choose an appropriate value for N.
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 configura-
tion file, as described in pcp.conf(5).
