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).
