NAME¶
pmerr - translate Performance Co-Pilot error codes into error messages
SYNOPSIS¶
pmerr code ...
pmerr -l
DESCRIPTION¶
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.
The alternative use of the
-l option causes all known error codes to be
listed, along with their symbolic names and error text.
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).
