NAME         top

       pmdagluster - Gluster Filesystem PMDA

DESCRIPTION         top

       pmdagluster is a Performance Metrics Domain Agent (PMDA) which
       exports metric values about mounted gluster filesystems using the
       gluster(8) command.  This PMDA exports metrics about volumes and
       bricks both local and remote to the node where pmdagluster is

       The gluster filesystem supports fine-grained control over enabling
       statistics on individual volumes, so that the values are optionally
       enabled or disabled on systems where they are not desired to be

       The pmstore(1) command can be used to enable and disable profiling of
       volumes.  Using the individual instances of the
       gluster.volume.profile metric, one can set their values (and
       associated profiling) either on (1) or off (0).  Additionally,
       pminfo(1) can report on the current status of profiling of each

            # pminfo ‐f gluster.volume.profile

                inst [0 or "gv0"] value 0
                inst [1 or "gv1"] value 1

            # pmstore ‐i "gv0" gluster.volume.profile 1
            gluster.volume.profile inst [0 or "gv0"] old value=0 new value=1

       Further details on the gluster filesystem can be found at .

INSTALLATION         top

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

           # cd $PCP_PMDAS_DIR/gluster
           # ./Install

       To uninstall, do the following as root:

           # cd $PCP_PMDAS_DIR/gluster
           # ./Remove

       pmdagluster is launched by pmcd(1) and should never be executed
       directly. The Install and Remove scripts notify pmcd(1) 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).
