PMDALMSENSORS(1) General Commands Manual PMDALMSENSORS(1)
NAME
pmdalmsensors - Linux hardware monitoring performance metrics domain agent (PMDA)
SYNOPSIS
$PCP_PMDAS_DIR/lmsensors/pmdalmsensors [-d domain] [-l logfile] [-U username]
DESCRIPTION
pmdalmsensors is a Performance Metrics Domain Agent (PMDA) which extracts performance metrics describing the state of hardware using the
lm-sensors on compatible motherboards.
The lmsensors PMDA exports metrics that measure fan speeds, core temperatures and voltage levels.
A brief description of the pmdalmsensors command line options follows:
-d It is absolutely crucial that the performance metrics domain number specified here is unique and consistent. That is, domain should
be different for every PMDA on the one host, and the same domain number should be used for the same PMDA on all hosts.
-l Location of the log file. By default, a log file named lmsensors.log is written in the current directory of pmcd(1) when pmdalmsen-
sors 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.
-U User account under which to run the agent. The default is the unprivileged "pcp" account in current versions of PCP, but in older
versions the superuser account ("root") was used by default.
INSTALLATION
If you want access to the names, help text and values for the lmsensors performance metrics, do the following as root:
# cd $PCP_PMDAS_DIR/lmsensors
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/lmsensors
# ./Remove
pmdalmsensors 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.
FILES
$PCP_PMCDCONF_PATH
command line options used to launch pmdalmsensors
$PCP_PMDAS_DIR/lmsensors/help
default help text file for the lmsensors metrics
$PCP_PMDAS_DIR/lmsensors/Install
installation script for the pmdalmsensors agent
$PCP_PMDAS_DIR/lmsensors/Remove
undo installation script for the pmdalmsensors agent
$PCP_LOG_DIR/pmcd/lmsensors.log

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 configura-
tion file, as described in pcp.conf(5).
