NAME         top

       pmdadm - Device Mapper PMDA

DESCRIPTION         top

       pmdadm is a Performance Metrics Domain Agent (PMDA) which exports
       metric values for Devic Mapper on the local system.

       This PMDA collects its data through the dmsetup(8) utility and
       requires that the program is installed in order to function.

       Further details on device mapper can be found at

INSTALLATION         top

       Install the DM PMDA by using the Install script as root:

             # cd $PCP_PMDAS_DIR/dm
             # ./Install

       To uninstall, do the following as root:

             # cd $PCP_PMDAS_DIR/dm
             # ./Remove

       pmdadm is launched by pmcd(1) and should never be executed directly.
       The Install and Remove scripts notify pmcd when the agent is
       installed or removed.

       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).
