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
Top Ten Processes By CPU Consumption are based on percent CPU used
Top Ten Processes By Memory Consumption are base on percent Memory used
