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. 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

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.
