NAME

       pmdanvidia - nvidia gpu metrics domain agent (PMDA)

SYNOPSIS

       $PCP_PMDAS_DIR/nvidia/pmdanvidia [-d domain] [-l logfile]

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.

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.

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).
