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
16       enabled 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       To uninstall, do the following as root:
44
45             # cd $PCP_PMDAS_DIR/gluster
46             # ./Remove
47
48       pmdagluster is  launched  by  pmcd(1)  and  should  never  be  executed
49       directly.  The Install and Remove scripts notify pmcd(1) when the agent
50       is installed or removed.

PCP ENVIRONMENT

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