nvmex

nvmex is a metrics exporter for nvidia graphic processing units (GPUs). To monitor the health and resource consumption of GPUs it utilizes the nvidia management library (libnividia-ml.so.1) usually distributed with the nvidia driver or a similar package (e.g. Solaris: driver/graphics/nvidia, Ubuntu: libnvidia-compute-*). Collected data can be exposed via HTTP in Prometheuse exposition format using the endpoint URL http://hostname:9400/metrics (port and IP are customizable of course) and thus visualized e.g. using Grafana, Netdata, or Zabbix.

In contrast to Nvidia's dcgm-exporter nvmex is written in plain C and thus it is compared to dcgm-exporter extremely lightweight (virtual memory size: 120 MiB vs. 5.7 GiB, resident set size: 6.5 MiB vs. 23.5..246 MiB), does not trash your disks with error logs, or hogs any cpu. You may run it on bare metal, or in any zone, container, or pod.

Requirements

Beside Nvidia's libnividia-ml.so.1 (usually provided by the libnvidia-compute-XYZ package) nvmex requires libprom and libmicrohttpd.

The nvml.h (usually provided by the cuda-nvml-dev-U-V package) used to compile this utility must match the libnividia-ml.so.1 library used on your machines and this in turn the version of the nvdia kernel module in use. The management library is usually backward compatible, so compiling against an older version and using it on machines with more recent versions of the NVML should work (but you may miss some metrics).

Build

Adjust the Makefile as needed, optionally set related environment variables (e.g. export CUDA_VERS=10.1 CC=gcc) and run make.

Repo

The official repository for nvmex is https://github.com/jelmd/nvmex . If you need some new features (or bug fixes), please feel free to create an issue there using https://github.com/jelmd/nvmex/issues .

Versioning

nvmex follows the basic idea of semantic versioning, but having the real world in mind. Therefore official releases have always THREE numbers (A.B.C), not more and not less! For nightly, alpha, beta, RC builds, etc. a .0 and possibly more dot separated digits will be append, so that one is always able to overwrite this one by using a 4th digit > 0.
