PMDAROOMTEMP(1)						       PMDAROOMTEMP(1)

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 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.

FILES

		 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_LOG_DIR/pmcd/roomtemp.log
		 default log file for error  messages  and  other  information
		 from pmdaroomtemp

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).
