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 pmdalmsensors 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.

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).
