Performance Metrics of a Nutanix VM Monitor

Gain a deep understanding of various metrics that affect the performance and health of your Nutanix virtual machines (VMs) with information on their storage containers, virtual disks, and virtual network interface controllers (NICs) to identify and troubleshoot issues. Simply add add an On-Premise Poller, a VM to monitor, and get started.

With Nutanix VM monitoring, you can:

Interpret Nutanix VM performance metrics

View individual component-wise performance from different tabs.

  • Summary: Lists key CPU, memory, and disk stats along with VM configuration, settings, and hardware summary details.
  • Storage Containers: Displays graphs for the top containers by space, data transfer, and latency of the storage controller along with basic details.
  • Virtual Disks: Displays the top virtual disks by I/O operations along with child-level controller metrics.
  • Virtual NICs: Shows various graphs on data received and transferred, including child-level Rx and Tx metrics.

Summary

Metrics Description
Storage Summary Overview of storage space
Memory Summary Overview of memory usage 
Disk Usage Split-up  Split-up of disk use across SSD, DAS-SATA, and cloud 
Hardware Summary  Number of vCPUs, network adapters, containers, and virtual disks 
CPU Usage (%)  Percentage of the total CPU cycles currently in use by the VM reported by the hypervisor 
CPU Ready Time (%)  Percentage of time a virtual machine waits to use the physical CPU out of the total CPU time allotted to the VM 
Memory Usage (%)  Percentage of memory used by the VM out of the total configured memory reported by the hypervisor 
Nutanix VM Configuration  Details like VM name, type, IP address, UUID, guest OS, power state, host name, type of hypervisor, protection domain name, etc. 
Nutanix VM Settings  Shows if the specifications like controller VM, Acropolis VM, running on NDFS, guest tools mounted, tool mounted, etc. are true or false 
Disk/Physical Usage (GiB and %)  The amount of physical storage space used currently in the VM 

Storage Containers

Metrics Description
Max Capacity (GiB) Total amount of storage capacity available to the storage container
Used Space (GiB) The amount of used storage space in the storage container
Physical Free Space (GiB) The amount of free storage space available to the storage container
Controller IOPS (count/sec) I/O operations per second (IOPS) for the storage container
Controller I/O Bandwidth (MB/sec) I/O bandwidth used per second for physical disk requests in the storage container 
Controller I/O Latency (ms) The average I/O latency for physical disk requests in the storage container 
Top Containers by Used Space (GiB)  Top containers based on the storage space used 
Top Containers by Free Space (GiB)  Top containers based on free space available 
Data Transferred from the Storage Controller (MB/sec)  Data transferred per second from storage controller to the VM 
I/O Latency of the Storage Controller (millisecs)  I/O latency in milliseconds from the storage controller 

Virtual Disks

Metrics Description
Flash Mode Indicates whether the flash mode feature is enabled or not for the VM
Capacity (MiB) The total disk capacity available to this VM 
Controller I/O Bandwidth (MB/sec) I/O bandwidth used per second for this VM 
Controller I/O Latency (ms)  The average I/O latency for this VM 
Controller IOPS (count/sec)  Rate of the VM reads and writes in IOPS reported by the controller 
Controller Read IOPS (%)  Rate of the VM reads in IOPS reported by the controller 
Controller Write IOPS (%)  Rate of the VM writes in IOPS reported by the controller 
Top Virtual Disks by I/O Operations (count/sec)  Top virtual disks based on the I/O operations per second 
Data Transferred from the Storage Controller (MB/sec)  Data transferred per second from storage controller to the VM 
I/O Latency of the Storage Controller (millisecs)  I/O latency in milliseconds from the storage controller 

Virtual NICs

Metrics Description
Virtual NIC The virtual NIC identification number
Port name  Port name through which the VM communicates 
Adapter type  The adaptor type defined for the virtual NIC
MAC address  The virtual NIC MAC address 
VLAN ID  The virtual NIC VLAN ID 
Rx Rate (KB/sec)  Rate at which data is transmitted 
Tx Rate (KB/sec)  Rate at which data is received 
Rx Packets  Number of packets received 
Tx Packets  Number of packets transferred 
Rx Packets Dropped  Number of the network received packets dropped 
Tx Packets Dropped  Number of the network transmitted packets dropped 
Error Rx Packets  The number of received packets with an error 
Error Tx Packets  The number of transmitted packets with an error 
Top Virtual NICs by Packets Received   The top virtual NICs based on the number of packets received 
Top Virtual NICs by Packets Transmitted  The top virtual NICs based on the number of packets transmitted 
Rx Rate of Virtual NICs (KB/sec)  The rate at which virtual NICs receive data 
Tx Rate of Virtual NICs (KB/sec)  The rate at which virtual NICs transmit data 
Rx Packets Dropped by Virtual NICs  The number of received packets dropped by the virtual NIC 
Tx Packets Dropped by Virtual NICs  The number of transmitted packets dropped by the virtual NIC 
Error Packets Received by Virtual NICs  The number of packets virtual NICs received with an error 
Error Packets Transmitted by Virtual NICs  The number of packets virtual NICs transmitted with an error
