    puts "#{uw_diskused} Gigabytes Used"
    puts "#{uw_cpuused}% CPU Used"
    puts "#{uw_tcpused} TCP Connections Used"
    puts "#{uw_udpused} UDP Connections Used"
    puts "#{uw_memused}% Active Memory Used"
    puts "#{uw_load} Average System Load Of The Past Minute"
    puts "#{uw_bandrx} Mbit/s Current Bandwidth Received"
    puts "#{uw_bandtx} Mbit/s Current Bandwidth Transmitted"
    puts "#{uw_diskioreads}/s Current Disk Reads Completed"
    puts "#{uw_diskiowrites}/s Current Disk Writes Completed"

Notes

  • Disk Used is a sum of all partitions calculated in Gigabytes

  • Disk Used Percentage is a total percentage of all disk partitions used

  • CPU Used is a percentage of current CPU being used

  • TCP/UDP Connections Used is a total count of each respectively

  • Active Memory Used is a percentage of active system memory being used

  • Load is the average load of the past minute

  • Bandwidth is current received and transmitted in Megabits

  • Disk IO is current disk reads and writes completed per second
