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).
