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
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
-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
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/mounts
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.

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).
