NAME

       pmdadm - Device Mapper PMDA

DESCRIPTION

       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 http://redhat.com

INSTALLATION

       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.

PCP ENVIRONMENT

       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).
