Instance Types page in the OpenStack view_24.2
The Instance Types tab enables you to see the resource usage by flavor at the cloud level which gives a clear idea of how the resources in the cloud are being utilized. For example, you can see spare VMs by a flavor of choice for all the cloud infrastructure elements.
The Instance Types page in the OpenStack view displays information for all types of hosts available, including parameters such as CPU, storage, and memory.
You can access this page in the TrueSight console using one of the following ways:
- Select Capacity > Views > Cloud > OpenStack and click the Instance Types tab
- In the OpenStack > Cloud page, navigate to the Related Information panel and click the Instance Types link.

Viewing the OpenStack Instance Types table
The Instance Types table lists the following information for each Instance Type in the selected cloud. For more information, see Sorting a table in the TrueSight console.
Instance Types table: Description of columns
Column | Description | Statistical Type | Metrics |
|---|---|---|---|
Name | Name of the instance type. | Last Value | NAME |
vCPUs | The number of vCPUs allocated in each instance type or flavor. | Last Value | CPU_NUM
|
Memory [GB] | The amount of memory allocated in each instance type or flavor. | Last Value | TOTAL_REAL_MEM |
Disk [GB] | The total disk space allocated in each instance type or flavor. | Last Value | DISK_SIZE |
Total CPU [GHz] | Total CPU capacity for a particular instance type, measured in Gigahertz. | Computed metric based on last value | SUM of (CPU_NUM*CPU_MHZ) of all instances of the type |
CPU Used [GHz] | Total CPU used by the VMs, measured in Gigahertz. | Computed metric based on average values | SUM of (CPU_UTILMHZ) of all instances of the type |
CPU Util [%] | Percentage of total CPU utilization. | Computed metric based on average values | SUM of (CPU_UTIL) of all instances of the type |
Total Memory [GB] | Total physical memory capacity, measured in Gigabytes. | Computed metric based on Last Value | SUM of (TOTAL_REAL_MEM) of all instances of the type |
Memory Used [GB] | Total physical memory used by the VMs, measured in Gigabytes. | Computed metric based on average values | SUM of (MEM_CONSUMED) of all instances of the type |
Memory Util [%] | Percentage of total physical memory utilized. | Computed metric based on average values | SUM of (MEM_UTIL) of all instances of the type |
Total Datastore [GB] | Total capacity of the datastore, measured in Gigabytes. | Computed metric based on Last Value | SUM of (DISK_SIZE) of all instances of the type |
Datastore Used [GB] | Total used space in the datastore, measured in Gigabytes. | Computed metric based on average values | SUM of (TOTAL_DSTORE_USED) of all instances of the type |
Datastore Util [%] | Percentage of total datastore capacity. | Computed metric based on average values | SUM of (TOTAL_DSTORE_UTIL) of all instances of the type |
Number of VMs | The number of Virtual Machines already created in the cloud. | Computed metric based on Last Value | COUNT of number of VMs of instance type |
Spare VMs | The number of Virtual Machines of the instance type that can be created using the unutilized resources in the cloud. | Computed in the data mart using last values of total capacity and average values of CPU, Memory and Storage of the instances in instance type | Total capacity and average value of CPU, Memory and Storage of the instances in instance type |
Limiting Resource | The resource that limits the number of additional VMs that can be placed in the cluster. Limiting resource may not necessarily exceed threshold, it is the least available of the three resources – CPU, MEMORY and STORAGE. | Computed metric based on average values | Resource with lowest Spare VMs among CPU, MEMORY, STORAGE |
Using data filters and other controls in tables
You can sort and filter the information that is displayed in tables to suit your need. For instance, you can show or hide columns, export the data to Excel, select a different cloud, clear the selected cloud, and so on.
