NAME
       pmdamounts - filesystem mounts performance metrics domain agent (PMDA)

SYNOPSIS
       $PCP_PMDAS_DIR/mounts/pmdamounts [-d domain] [-l logfile] [-U username]

DESCRIPTION
       pmdamounts is a simple Performance Metrics Domain Agent (PMDA) which monitors availability
       of a given set of filesystem mounts.

       The mounts PMDA exports metrics	that  reflect  whether	the  configured  filesystems  are
       mounted	("up")	or  not.   The	list  of  mount  points  to  monitor is specified via the
       $PCP_PMDAS_DIR/mounts/mounts.conf file which simply  contains  one  line  for  each  mount
       point.

       Note  that the platform kernel PMDA exports a more extensive set of filesystem metrics for
       every mounted filesystem - this PMDA is primarily  intended  for  availability  monitoring
       using the mounts.up metric.

       A brief description of the pmdamounts 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 mounts.log is written in the
	    current directory of pmcd(1) when pmdamounts 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 mounts performance  metrics,
       do the following as root:

	    # cd $PCP_PMDAS_DIR/mounts
	    # ./Install

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

	    # cd $PCP_PMDAS_DIR/mounts
	    # ./Remove

       pmdamounts  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

		 command line options used to launch pmdamounts
       $PCP_PMDAS_DIR/mounts/help
		 default help text file for the mounts metrics
       $PCP_PMDAS_DIR/mounts/Install
		 installation script for the pmdamounts agent
       $PCP_PMDAS_DIR/mounts/Remove
		 undo installation script for the pmdamounts agent
       $PCP_LOG_DIR/pmcd/mounts.log
		 default log file for error messages and other information from pmdamounts

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 config-
       uration file, as described in pcp.conf(5).
