NAME
pmdaroomtemp - room temperature performance metrics domain agent (PMDA)
SYNOPSIS
$PCP_PMDAS_DIR/roomtemp/pmdaroomtemp [-d domain] [-l logfile]
DESCRIPTION
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.
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.

PCP ENVIRONMENT
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).
