PMDAGLUSTER(1) General Commands Manual PMDAGLUSTER(1)
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
http://www.gluster.org .
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).
