pmdagluster - Gluster Filesystem PMDA
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

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.
$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
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).
