Окружение PCP (PCP environment)
Environment variables with the prefix PCP_ are used to
parameterize the file and directory names used by PCP. On each
installation, the file /etc/pcp.conf contains the local values
for these variables. The $PCP_CONF variable may be used to
specify an alternative configuration file, as described in
pcp.conf(5).
When executing shell actions, pmie overrides two variables - IFS
and PATH - in the environment of the child process. IFS is set
to "\t\n". The PATH is set to a combination of a default path
for all platforms ("/usr/sbin:/sbin:/usr/bin:/bin") and several
configurable components. These are (in this order):
$PCP_BIN_DIR, $PCP_BINADM_DIR and $PCP_PLATFORM_PATHS.
When executing popup alarm actions, pmie will use the value of
$PCP_XCONFIRM_PROG as the visual notification program to run.
This is typically set to pmconfirm(1), a cross-platform dialog
box.
