NAME

6       pmdadenki - metrics related to the systems electrical consumption

SYNOPSIS

9       $PCP_PMDAS_DIR/denki/pmdadenki [-d domain] [-l logfile]
10

DESCRIPTION

12       pmdadenki  is  a Performance Metrics Domain Agent (PMDA) which extracts
13       electricity related performance metrics.
14
15       Currently, metrics from RAPL (on Intel cpus) and battery charge  values
16       are available, if supported by the hardware.
17
18       -l Location of the log file.  By default, a log file named denki.log is
19       written in the current directory of pmcd(1) when pmdadenki is  started,
20       i.e.   $PCP_LOG_DIR/pmcd.   If the log file cannot be created or is not
21       writable, output is written to the standard error instead.
22

INSTALLATION

24       The denki PMDA is installed and available by default on Linux.  If  you
25       want to undo the installation, do the following as root:
26
27            # cd $PCP_PMDAS_DIR/denki
28            # ./Remove
29
30       If  you want to establish access to the names, help text and values for
31       the denki metrics once more, after removal, do the following as root:
32
33            # cd $PCP_PMDAS_DIR/denki
34            # ./Install
35
36       pmdadenki is launched by pmcd(1) and should never be executed directly.
37       The  Install  and  Remove  scripts notify pmcd(1) when the agent is in‐
38       stalled or removed.

PCP ENVIRONMENT

54       Environment variables with the prefix PCP_ are used to parameterize the
55       file and directory names used by PCP.  On each installation,  the  file
56       /etc/pcp.conf  contains  the  local  values  for  these variables.  The
57       $PCP_CONF variable may be used to specify an alternative  configuration
58       file, as described in pcp.conf(5).
