Turbonomic now supports configuring Turbonomic policies to control both on-premises resize actions and cloud scale actions through the "Scaling target vCPU Utilization" and "Scaling target vMEM Utilization" settings. Before now, Turbonomic user could only set these settings for Cloud VMs.
What is Target Utilization?
Scaling target utilization / desired utilization determines the midpoint of utilization range that is considered optimal. The lower and upper limits for this range are always 5% below and above the midpoint, respectively. For example, A midpoint of 70% means that optimal utilization is between 65% and 75%. Turbonomic takes this optimal utilization range (along with other resize factors) into consideration when it generates resize actions.
Configuring vCPU / vMEM target utilization
Customers can set desired scaling target utilization values for vCPU and vMEM by navigating to the Virtual Machine "Automation Policies". These settings are available under the "Operational Constraints" section.
Understanding the Virtual machines resize actions
Navigate to the Action Center and select the "Virtual Machines" option under the Resize section in the ON-PREM tab to view the resize actions. To get more information, click on the details button that is associated with the individual actions.
- vMEM Congestion / vCPU Congestion (Resize UP)
When the current utilization exceeds the desired utilization vMem / vCPU, it means that there congestion on the resource which should generate a resize up action. This should bring down the current utilization to its ideal level.
vMEM Resize UP
vCPU Resize UP
- Underutilized vMEM / Underutilized vCPU (Resize Down)
When the current utilization is below the desired utilization (Underutilization of vMem / vCPU), a resize down action will be generated.
