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 manner 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.
