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).
