NAME

       pmpost - append messages to the Performance Co-Pilot notice board

SYNOPSIS

       $PCP_BINADM_DIR/pmpost message

DESCRIPTION

       pmpost will append the text message to the end of the Performance Co-Pilot (PCP) notice board file ($PCP_LOG_DIR/NOTICES) in an atomic man-
       ner that guards against corruption of the notice board file by concurrent invocations of pmpost.

       The PCP notice board is intended to be a persistent store and clearing house for important messages relating to the operation  of  the  PCP
       and the notification of performance alerts from pmie(1) when other notification options are either unavailable or unsuitable.

       Before  being  written,	messages are prefixed by the current time, and when the current day is different to the last time the notice board
       file was written, pmpost will prepend the message with the full date.

       If the notice board file does not exist, pmpost will create it.	pmpost would usually run from long-running PCP daemons executing under the
       (typically unprivileged) $PCP_USER and $PCP_GROUP accounts.  The file should be owned by root, and group writable by the $PCP_GROUP group.

NAME

       pcp.conf - the Performance Co-Pilot configuration and environment file

SYNOPSIS

       /etc/pcp.conf

DESCRIPTION

       When  using  Performance Co-Pilot (PCP) tools and utilities and when calling PCP library functions, a standard set of environment variables
       are defined in /etc/pcp.conf.  These variables are generally used to specify the location of various PCP pieces in the file system and  may
       be  loaded  into  shell scripts by sourcing the /etc/pcp.env(5) shell script and queried by C/C++ programs using the pmGetConfig(3) library
       function.  If a variable is already defined in the environment, the values in pcp.conf do not override those values,  i.e.  the	values	in
       pcp.conf serve as installation defaults only.

       Both  the  pcp.env  and	pcp.conf  files  are expected to be found in /etc by default.  If required, the pcp.conf file may be relocated and
       PCP_CONF set in the environment to specify the full path to the new location.  The pcp.env file can not be relocated (this is the only hard
       coded path required by PCP).

       The syntax rules for pcp.conf are as follows :

       1.  the general syntax is
						       PCP_VARIABLE_NAME=variable value to end of line

       2.  lines that begin with # and all blank lines are ignored.

       3.  all variables must be prefixed with PCP_.  This is a security issue - variables that do not have this prefix will be silently ignored.

       4.  there  should  be  no  space  between the variable name and the literal = and no space between the = and the variable value (unless the
	   value actually starts with a space).  This is required because the pcp.conf file may be sourced directly by Makefiles as well as inter-
	   preted by the pcp.env script and the pmGetConfig function.

       5.  variable  values  may  contain  spaces  and should not be quoted.  The pcp.env script automatically quotes all variable values from the
	   character immediately following the = through to the end of the line.

       For further details and an explanation of the use of each variable, see the comments in the /etc/pcp.conf file itself.

ENVIRONMENT

       The PCP_CONF environment variable specifies an alternative path to the pcp.conf file.
