GPU Server Status Monitor with NodeJS (NVIDIA SMI Javascript Wrapper + Web Interface)

Web Browser interface for GPU Server Monitoring Preview

Usage

Access the local ip address / domain name of the machine running "ServerInfo Webserver" module with a Web Browser (Tested on Chromium)

Server Info RESTAPI

When installed and activated on a specific server, provides a REST API to cccess the later's info, namely GPU usage status, RAM Memory usage and HDD info (!)

Setup

! The scripts support Ubuntu and Centos only for now

  • If installing from the "to be monitored" GPU server directly, just run "install_serverinfo_restapi_remote.sh".
  • Else, when installing on multiple servers, first make sure to have root access on each of the remote GPU servers as well as root ssh access, edit the "HOSTS" variable "install_serverinfo_restapi.sh" with the hostnames (requires DNS config on your network) or ip addresses of the target GPU machines, then run the script.

Central Monitoring WebApp

Provide a Web Browser accessible interface to monitor GPU server status of machines where the "Server Info RESTAPI" counterpart is installed.

Setup

- Copy the "serverinfo_webserver" sub module to desired location (/opt recommended)
- Make sure you have NodeJS >= 10 intalled  (Tested on 11.6 and 11.11 Arch Linux, Centos 7 and Ubuntu 16.04)
- Access the folder with a terminal and run "npm install" to install necessary dependencies
Either:
- Run "node main.js" directly from the directory (dirty, as "killall nodejs" and similar command will stop the nodejs server, etc ...)
- Copy the appropriate systemd service unit file to "/etc/systemd/system/" and run "systemctl daemon-reload && systemctl enable serverinfo_webserver_XXX && systemctl start serverinfo_webserver_XXX"

Improvement (?)

  • Easy to understand General / GPU Usage state summary
  • get_meminfo: Active memory vs Used Memory
  • get_hddinfo: Doesn't display HDD info for Ubuntu based server, wut !?
  • Add Alert in Webapp when a full HD detected somewhere
  • Optimize variables mgmt in central monitor app
  • Collapse Storage Info
  • Badge close to "Online" to signlal harddrive critical condition
  • Slack Notification on full hard drives
  • Service units: Node ~app.js or npm start: Which is better ?
