PMDADENKI(1) General Commands Manual PMDADENKI(1)
pmdadenki - metrics related to the systems electrical consumption
$PCP_PMDAS_DIR/denki/pmdadenki [-d domain] [-l logfile]
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.
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_PMCDCONF_PATH
command line options used to launch pmdadenki
$PCP_PMDAS_DIR/denki/help
default help text file for the denki metrics
$PCP_PMDAS_DIR/denki/Install
installation script for the pmdadenki agent
$PCP_PMDAS_DIR/denki/Remove
undo installation script for the pmdadenki agent
$PCP_LOG_DIR/pmcd/denki.log
default log file for error messages and other information
from pmdadenki
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).
PCPIntro(1), pmcd(1), denki/READMEfile pcp.conf(5) and
pcp.env(5).
