PMDAROOMTEMP(1)          General Commands Manual         PMDAROOMTEMP(1)

NAME         top

       pmdaroomtemp - room temperature performance metrics domain agent
       (PMDA)

SYNOPSIS         top

       $PCP_PMDAS_DIR/roomtemp/pmdaroomtemp [-d domain] [-l logfile]

DESCRIPTION         top

       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         top

       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         top

       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).
