NAME

       pmdagluster - Gluster Filesystem PMDA

DESCRIPTION

       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.pro-
       file metric, one can set their values (and associated profiling) either on (1) or off (0).  Additionally, pminfo(1) can report on the  cur-
       rent 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

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.

FILES

       $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

PCP ENVIRONMENT

       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 configura-
       tion file, as described in pcp.conf(5).

NAME

       pmdatrivial - trivial performance metrics domain agent (PMDA)

SYNOPSIS

       $PCP_PMDAS_DIR/trivial/pmdatrivial [-d domain] [-l logfile] [-U username]

DESCRIPTION

       pmdatrivial is the simplest possible Performance Metrics Domain Agent (PMDA) which exports a single performance metric, the time in seconds
       since the 1st of January, 1970.

       The trivial PMDA is shipped as source code and is designed to be an aid for PMDA developers.

       A brief description of the pmdatrivial command line options follows:

       -d   It is absolutely crucial that the performance metrics domain number specified here is unique and consistent.  That is,  domain  should
	    be different for every PMDA on the one host, and the same domain number should be used for the same PMDA on all hosts.

       -l   Location of the log file.  By default, a log file named trivial.log is written in the current directory of pmcd(1) when pmdatrivial is
	    started, i.e.  $PCP_LOG_DIR/pmcd.  If the log file cannot be created or is not writable, output  is  written  to  the  standard  error
	    instead.

       -U   User  account  under  which  to run the agent.  The default is the unprivileged "pcp" account in current versions of PCP, but in older
	    versions the superuser account ("root") was used by default.

INSTALLATION

       If you want access to the names, help text and values for the trivial performance metrics, do the following as root:

	    # cd $PCP_PMDAS_DIR/trivial
	    # ./Install

       If you want to undo the installation, do the following as root:

	    # cd $PCP_PMDAS_DIR/trivial
	    # ./Remove

       pmdatrivial 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.
