NAME

       pmdadenki - metrics related to the systems electrical consumption

SYNOPSIS

       $PCP_PMDAS_DIR/denki/pmdadenki [-d domain] [-l logfile]

DESCRIPTION

       pmdadenki  is a Performance Metrics Domain Agent (PMDA) which extracts electricity related
       performance metrics.

       Currently, metrics from RAPL (on Intel cpus) and battery charge values are  available,  if
       supported by the hardware.

       -l  Location  of  the  log file.  By default, a log file named denki.log is written in the
       current directory of pmcd(1) when pmdadenki 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

       The denki PMDA is installed and available by default on Linux.  If you want  to  undo  the
       installation, do the following as root:

            # cd $PCP_PMDAS_DIR/denki
            # ./Remove

       If  you  want to establish access to the names, help text and values for the denki metrics
       once more, after removal, do the following as root:

            # cd $PCP_PMDAS_DIR/denki
            # ./Install

       pmdadenki 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).
