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
       running.

       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 monitored.

       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
       volume.

            # pminfo ‐f gluster.volume.profile

            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
       http://www.gluster.org .

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.

           installation script for the pmdagluster agent

PCP ENVIRONMENT         top

       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).
