PMPOST(1)                General Commands Manual               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 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 and writable by the $PCP_USER
       user, and readable by others.
