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.

       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 configuration file, as described in pcp.conf(5).
