pmdaroomtemp - room temperature performance metrics domain agent
(PMDA)
$PCP_PMDAS_DIR/roomtemp/pmdaroomtemp [-d domain] [-l logfile]
pmdaroomtemp is a Performance Metrics Domain Agent (PMDA) which
exports the temperature from one or more sensors built using the
DS2480 and DS1280 chipsets and MicroLAN technology from Dallas
Semiconductor Corporation.
The roomtemp PMDA exports metrics that reflect the temperatures from
one or more of these devices, in both degrees Celcius and Fahrenheit.
Each metric has one instance for each temperature sensor device. The
external instance identifiers are the serial numbers (in hex) of the
DS1280 chips discovered when the MicroLAN was probed.
A brief description of the pmdaroomtemp 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
roomtemp.log is written in the current directory of pmcd(1) when
pmdaroomtemp 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.
If you want access to the names, help text and values for the
roomtemp performance metrics, do the following as root:
# cd $PCP_PMDAS_DIR/roomtemp
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/roomtemp
# ./Remove
pmdaroomtemp 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 pmdaroomtemp
$PCP_PMDAS_DIR/roomtemp/help
default help text file for the roomtemp metrics
$PCP_PMDAS_DIR/roomtemp/Install
installation script for the pmdaroomtemp agent
$PCP_PMDAS_DIR/roomtemp/Remove
undo installation script for the pmdaroomtemp agent
$PCP_LOG_DIR/pmcd/roomtemp.log
default log file for error messages and other information
from pmdaroomtemp
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).
