NAME

       pmdagluster - Gluster Filesystem PMDA

DESCRIPTION

       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

       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.

FILES

       $PCP_PMDAS_DIR/gluster/Install
           installation script for the pmdagluster agent

       $PCP_PMDAS_DIR/gluster/Remove
           undo installation script for the pmdagluster agent

       $PCP_LOG_DIR/pmcd/gluster.log
           default log file for error messages from pmdagluster

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).
