Basic CPU/ Mem/ NET/ Disk displays metric information on the virtual machine (vm) about usage CPU, Memory, Network, and Disk on the virtual machine (vm) . On section Basic CPU/ Mem/ NET/ Disk displays several metrics including CPU Basic, Memory Basic, Network Traffic Basic, Memory Basic Percentage, and Disk Space Used Basic.
CPU Basic mdisplays workload metrics on the CPU and the following is a description of CPU activity based on color.
Busy System in yellow ( ) means how much CPU is used by the system as a whole.
Busy User in blue ( ) means how much CPU is used by the user.
Busy Iowait in red ( ) meansthe time spent by the CPU waiting for an I/O operation to complete.
Busy IRQs in orange (). IRQ (Interrupt Request) or Interrupt Request is a mechanism that exists within a virtual machine (vm) to notify the CPU that it requires attention.Busy IRQs meansinterrupt request mechanism used by a virtual machine (vm) to notify the CPU that it requires immediate attention.
Busy Other in young( ) means the other machine is busy.
Idle in green ( ) means the CPU is not active.
Memory Basic mdisplays workload metrics on memory, and the following is an explanation of memory busyness based on color.
Displays workload metrics on network traffic. To see a description of network traffic activity based on the color located below the following metrics:
Displays workload metrics on a basic percentage of memory and the following is an explanation of the basic memory description based on color.
Displays workload metrics on a basic percentage of memory. To see a description of the activity then the basic percentage of memory based on the color located below the metrics is as follows:
RAM Total in light green() means the total physical memory capacity owned by the virtual machine (vm) .
RAM Used in yellow() means the amount of memory that is being used by the operating system and applications at any one time.
RAM Cache+Buffer withInblue color() means a certain amount of memory allocated for caching and buffering data is useful for improving system performance.
RAM Free in dark green () means the amount of memory that is not used by the system.
SWAP Used with colorred() means that much of the remaining SWAP space is currently used by the system in the virtual machine (vm) .
recv ens3 with wgreen color () means the amount of data received by the ens3 network interface.
recv itin yellow () means the amount of data received by the loopback interface.
trans ens3in blue () means the amount of data sent by the ens3 network interface.
trans lo in orange () means the amount of data sent through the loopback interface.
RAM Used in dark green () the amount of memory being used by the operating system and applications at any one time in percentage terms.
RAM Cache + Buffer in blue () means a certain amount of memory allocated for data caching and buffering is useful for increasing system performance in a percentage measure.
RAM Free in light green () means the amount of memory that is not used by the system in percentage size.
SWAP Used in red () means the amount of SWAP remaining space currently used by the system in the virtual machine (vm) in percentage size.
/ in green() means the use of the root directory on the system.
/boot/efi in yellow() means the use of the location directory where data related to the EFI boot system is stored (Extensible Firmware Interface).
/run in blue () means the use of a temporary data storage directory that is needed while the system is running.
/run/lock in orange() means the use of a lock file storage directory used by the system to avoid data corruption caused by concurrent access of several processes to certain resources.
/run/snapd/ns in red() means the use of the package management system directory, while ns is the namespace.
/run/user/0 in dark blue () means the use of a directory where files and runtime information are stored for the user with ID 0, which is usually root.
