PMDAROOMTEMP(1)PMDAROOMTEMP(1)NAMEpmdaroomtemp - room temperature performance metrics domain agent (PMDA)
SYNOPSIS
$PCP_PMDAS_DIR/roomtemp/pmdaroomtemp [-d domain] [-l logfile]
DESCRIPTIONpmdaroomtemp 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 Cor‐
poration.
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 num‐
ber 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.
INSTALLATION
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.

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).
