PMPOST(1)PMPOST(1)NAMEpmpost - append messages to the Performance Co-Pilot notice board
SYNOPSIS
$PCP_BINADM_DIR/pmpost message
DESCRIPTIONpmpost will append the text message to the end of the Performance Co-
Pilot (PCP) notice board file ($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. 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.
