NAME

6       pmdagluster - Gluster Filesystem PMDA
7

DESCRIPTION

9       pmdagluster  is a Performance Metrics Domain Agent (PMDA) which exports
10       metric values about mounted gluster filesystems  using  the  gluster(8)
11       command.  This PMDA exports metrics about volumes and bricks both local
12       and remote to the node where pmdagluster is running.
13
14       The gluster filesystem supports fine-grained control over enabling sta‐
15       tistics  on  individual  volumes, so that the values are optionally en‐
16       abled or disabled on systems where they are not  desired  to  be  moni‐
17       tored.
18
19       The  pmstore(1)  command can be used to enable and disable profiling of
20       volumes.  Using the individual instances of the  gluster.volume.profile
21       metric,  one  can set their values (and associated profiling) either on
22       (1) or off (0).  Additionally, pminfo(1) can report on the current sta‐
23       tus of profiling of each volume.
24
25            # pminfo ‐f gluster.volume.profile
26
27            gluster.volume.profile
28                inst [0 or "gv0"] value 0
29                inst [1 or "gv1"] value 1
30
31            # pmstore ‐i "gv0" gluster.volume.profile 1
32            gluster.volume.profile inst [0 or "gv0"] old value=0 new value=1

INSTALLATION

38       Install the gluster PMDA by using the Install script as root:
39
40           # cd $PCP_PMDAS_DIR/gluster
41           # ./Install
42
43
44       To uninstall, do the following as root:
45
46           # cd $PCP_PMDAS_DIR/gluster
47           # ./Remove
48
49       pmdagluster is launched by pmcd(1) and should  never  be  executed  di‐
50       rectly. The Install and Remove scripts notify pmcd(1) when the agent is
51       installed or removed.

PCP ENVIRONMENT

64       Environment variables with the prefix PCP_ are used to parameterize the
65       file  and  directory  names used by PCP. On each installation, the file
66       /etc/pcp.conf contains the  local  values  for  these  variables.   The
67       $PCP_CONF  variable may be used to specify an alternative configuration
68       file, as described in pcp.conf(5).
