BOP Blog: Server Maintenance Script

Server Maintenance Script

20th April 2024 / 11:45 PM

I wrote a small script to make maintaining the BOP webserver way simpler.

It automatically starts up whenever an SSH connection is established to the server. It will then print some statistics like CPU temperature, CPU usage, RAM usage and internet connectivity.

This is what is looks like in usage:




Since I will probably change the script later on, you can look at the up-to-date version on GitHub.

Or take a look at the first version right here: 



  #!/bin/bash

  clear

  echo 'Welcome to BytesOfProgress System Utility!'

  echo

  sleep 0.5

  echo 'You can always start this utility by typing "bop"!'

  sleep 1

  sensors | grep Core

  #------------------------------------------------------------------------------

  echo 'CPU Usage:'

  grep -E '^cpu[0-9]+ ' /proc/stat | awk 'NR <= 2 {usage=($2+$4)*100/($2+$4+$5+$6)} {print "Core " NR-1 ": " usage "%"}'

  echo

  #------------------------------------------------------------------------------

  echo 'RAM Usage:'

  awk '/MemTotal/ {total=$2} /MemAvailable/ {available=$2} END {usage=((total-available)/total)*100; printf "Percent: %.2f%%\n", usage}' /proc/meminfo
  awk '/MemTotal/ {total=$2} /MemAvailable/ {available=$2} END {printf "MiB: %d / %d MB\n", (total-available)/1024, total/1024}' /proc/meminfo
