Синопсис (Synopsis)
$PCP_PMDAS_DIR/nvidia/pmdanvidia [-d domain] [-l logfile]
Описание (Description)
pmdanvidia is a Performance Metrics Domain Agent (PMDA) which
extracts performance metrics describing the metrics available on
NVIDIA GPU cards via the NVML library.
The nvidia PMDA exports metrics that measure gpu activity, memory
utilization, fan speed, etc on NVIDIA Tesla and Quadro cards.
Metrics are unlikely to be available for consumer class cards.
A brief description of the pmdanvidia 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
nvidia.log is written in the current directory of pmcd(1)
when pmdanvidia 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.
Установка (Installation)
The nvidia PMDA is not installed and available by default. If
you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/nvidia
# ./Remove
If you want to establish access to the names, help text and
values for the nvidia performance metrics once more, after
removal, do the following as root:
# cd $PCP_PMDAS_DIR/nvidia
# ./Install
pmdanvidia 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.

Окружение PCP (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).
