AUTOMATIC RESTART
It is often useful for pmie processes to be started and stopped
when the local host is booted or shutdown, or when they have been
detected as no longer running (when they have unexpectedly exited
for some reason). Refer to pmie_check(1) for details on
automating this process.
Optionally, each system running pmcd(1) may also be configured to
run a ``primary'' pmie instance. This pmie instance is launched
by $PCP_RC_DIR/pmie, and is affected by the files
$PCP_SYSCONF_DIR/pmie/control, $PCP_SYSCONF_DIR/pmie/control.d
(use chkconfig(8), systemctl(1) or similar platform-specific
commands to activate or disable the primary pmie instance) and
$PCP_VAR_DIR/config/pmie/config.default (the default initial
configuration file for the primary pmie).
The primary pmie instance is identified by the -P option. There
may be at most one ``primary'' pmie instance on each system. The
primary pmie instance (if any) must be running on the same host
as the pmcd(1) to which it connects (if any), so the -h and -P
options are mutually exclusive.
