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.
