PMDAGLUSTER(1)PMDAGLUSTER(1)NAMEpmdagluster - Gluster Filesystem PMDA
DESCRIPTIONpmdagluster 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 sta‐
tistics on individual volumes, so that the values are optionally
enabled or disabled on systems where they are not desired to be moni‐
tored.
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 sta‐
tus 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

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.

Environment variables with the prefix PCP_ are used to parameterise 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).
