Описание (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.
Установка (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.

Окружение PCP (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).
