PMDANVIDIA(1) General Commands Manual PMDANVIDIA(1)
pmdanvidia - nvidia gpu metrics domain agent (PMDA)
$PCP_PMDAS_DIR/nvidia/pmdanvidia [-d domain] [-l logfile]
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.
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.
$PCP_PMCDCONF_PATH
command line options used to launch pmdanvidia
$PCP_PMDAS_DIR/nvidia/help
default help text file for the nvidia metrics
$PCP_PMDAS_DIR/nvidia/Install
installation script for the pmdanvidia agent
$PCP_PMDAS_DIR/nvidia/Remove
undo installation script for the pmdanvidia agent
$PCP_LOG_DIR/pmcd/nvidia.log
default log file for error messages and other information
from pmdanvidia
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), pcp.conf(5) and pcp.env(5).
