PMDALMSENSORS(1)					      PMDALMSENSORS(1)

NAME
       pmdalmsensors  -	 Linux	hardware monitoring performance metrics domain
       agent (PMDA)

SYNOPSIS
       $PCP_PMDAS_DIR/lmsensors/pmdalmsensors [-d  domain]  [-l	 logfile]  [-U
       username]

DESCRIPTION
       pmdalmsensors  is  a  Performance  Metrics  Domain  Agent  (PMDA) which
       extracts performance metrics describing the state of hardware using the
       lm-sensors on compatible motherboards.

       The  lmsensors  PMDA exports metrics that measure fan speeds, core tem‐
       peratures and voltage levels.

       A brief description of the pmdalmsensors 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 lmsen‐
	    sors.log is written in  the	 current  directory  of	 pmcd(1)  when
	    pmdalmsensors  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.

       -U   User  account  under  which	 to run the agent.  The default is the
	    unprivileged "pcp" account in current  versions  of	 PCP,  but  in
	    older versions the superuser account ("root") was used by default.

INSTALLATION
       If you want access to the names, help text and values for the lmsensors
       performance metrics, do the following as root:

	    # cd $PCP_PMDAS_DIR/lmsensors
	    # ./Install

       If you want to undo the installation, do the following as root:

	    # cd $PCP_PMDAS_DIR/lmsensors
	    # ./Remove

       pmdalmsensors 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
       $PCP_PMCDCONF_PATH
		 command line options used to launch pmdalmsensors
       $PCP_PMDAS_DIR/lmsensors/help
		 default help text file for the lmsensors metrics
       $PCP_PMDAS_DIR/lmsensors/Install
		 installation script for the pmdalmsensors agent
       $PCP_PMDAS_DIR/lmsensors/Remove
		 undo installation script for the pmdalmsensors agent
       $PCP_LOG_DIR/pmcd/lmsensors.log
		 default log file for error  messages  and  other  information
		 from pmdalmsensors

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).
