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.

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).
