NAME

       pmdadenki - metrics related to the systems electrical consumption

SYNOPSIS

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

DESCRIPTION

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

       Currently, metrics from the Running Average Power Limit (RAPL) Intel  CPU  feature,  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).

DEBUGGING OPTIONS

       The  -D or --debug option enables the output of additional diagnostics on stderr to help triage problems,
       although the information is sometimes cryptic and primarily intended to provide guidance  for  developers
       rather  end-users.  debug is a comma separated list of debugging options; use pmdbg(1) with the -l option
       to obtain a list of the available debugging options and their meaning.

       Debugging options specific to pmdadenki are as follows:
       ┌────────┬─────────────────────┐
       │ Option │ Description         │
       ├────────┼─────────────────────┤
       │ appl0  │ verbose diagnostics │
       └────────┴─────────────────────┘
