PMDAMOUNTS(1) General Commands Manual PMDAMOUNTS(1)
pmdamounts - filesystem mounts performance metrics domain agent
(PMDA)
$PCP_PMDAS_DIR/mounts/pmdamounts [-d domain] [-l logfile] [-U
username]
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.
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_PMCDCONF_PATH
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
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).
