PMPOST(1)							     PMPOST(1)

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 concur‐
       rent 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  notifi‐
       cation 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.	Due to
       the importance of the notice board file, pmpost is typically  installed
       as  a  setuid(2)	 root program and so the notice board is owned by, and
       writable only by, root.

FILES
       $PCP_LOG_DIR/NOTICES
		 the PCP notice board file

PCP ENVIRONMENT
       The file /etc/pcp.conf contains the local values	 for  PCP_  variables.
       Because	pmpost	is  setuid(1),	only the settings in /etc/pcp.conf are
       used.  In addition, the $PCP_CONF variable may not be used  to  specify
       an alternative configuration file for pmpost.
