PMERR(1)                 General Commands Manual                 PMERR(1)

NAME         top

       pmerr - translate Performance Co-Pilot error codes into error
       messages

SYNOPSIS         top

       pmerr [-?]  code ...
       pmerr -l

DESCRIPTION         top

       pmerr accepts standard Performance Co-Pilot (PCP) error codes via
       the code argument(s) and generates the corresponding error text.

       Each code may be an integer, a hexadecimal value or a hexadecimal
       value prefixed by either ``0x'' or ``0X''.

       Error codes must be less than zero, so if code is a positive
       number, a warning message is produced, and the negated value is
       used.

OPTIONS         top

       The available command line options are:

       -l, --list
            This alternative invocation causes all known error codes to
            be listed, along with their symbolic names and error text.

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

PCP ENVIRONMENT         top

       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).
