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).
