Global default policy
Use these settings to modify Turbonomic analysis globally for any scope of your environment. These defaults affect both default and user-defined automation policies.
Disable all actions
Attribute | Default setting |
---|---|
Disable All Actions | Off |
When this is ON, Turbonomic dos not generate any actions for your environment. For example, assume you have configured a number of polices that automate actions, but you want to stop making changes to the entire environment for a period of time. Turn this ON to stop all execution with a single setting.
VM growth observation period
Attribute | Default value |
---|---|
VM Growth Observation Period | 1 month |
Use this setting to specify how much historical data the Turbonomic analysis will use to calculate time to exhaustion of your cluster resources.
Turbonomic runs nightly plans to calculate headroom for the clusters in your on-prem environment. To review your cluster headroom in dashboards, set the view scope to a cluster. With that scope, the view includes charts to show headroom for that cluster, as well as time to exhaustion of the cluster resources.
To calculate cluster growth trends, analysis uses historical data for the given clusters. With VM Growth Observation Period, you can specify how much historical data the headroom analysis will use to calculate time to exhaustion of your cluster resources. For example, if cluster usage is growing slowly, then you can set the observation to a period that is long enough to capture that rate of growth.
If the historical database does not include at least two entries in the monthly data for the cluster, then analysis uses daily historical data.
Allow unlimited host provisioning
Attribute | Default setting |
---|---|
Allow Unlimited Host Provisioning | Off |
By default, Turbonomic allows overprovisioning hosts up to 10 times their memory capacity, and up to 30 times their CPU capacity. When this setting is ON, Turbonomic removes these overprovisioning limits to allow VM placements on already overprovisioned hosts.
This setting does not stop Turbonomic from recommending actions to provision new hosts in clusters.
Enable analysis of on-prem volumes
Attribute | Default setting |
---|---|
Enable Analysis of On-prem Volumes | On |
On-prem volumes represent VM Disks discovered by hypervisor targets. A VM will have one volume for each configured disk and another volume (representing the configuration) that always moves with Disk 1.
-
On (default)
Turbonomic analyzes resources on each volume independently. In the real-time market and on-prem plans, any action to move VM storage migrates volumes to the most optimal datastore. A Migrate to Cloud plan will recommend storage for each volume.
For example, assume a VM with three disks. Disks 1 and 3 are on Datastore A, while Disk 2 is on Datastore B.
-
During a storage migration, VM Disk volumes 1, 2, and 3 can migrate to different datastores.
-
A Migrate to Cloud plan will recommend three separate storage disks for VM Disk volumes 1, 2, and 3.
Note:When this setting is enabled, your Turbonomic instance uses more memory and storage to perform its analysis. If you experience performance issues when this setting is enabled, review your VM automation policies and verify that Storage Move actions are in Recommend or Manual mode. In addition, review your storage placement policies to ensure that individual VM volumes can be placed on the expected storage.

-
Off
Turbonomic analyzes volume resources as part of VM analysis. In the real-time market and on-prem plans, any action to move VM storage ensures that volumes stay together on the underlying datastore. A Migrate to Cloud plan will recommend storage per datastore to hold all the VM Disks currently on the datastore.
For example, assume a VM with three disks. Disks 1 and 3 are on Datastore A, while Disk 2 is on Datastore B.
-
During a storage migration, VM Disk volumes 1 and 3 will stay on the same datastore.
-
A Migrate to Cloud plan will recommend a storage disk for VM Disk volumes 1 and 3, and another storage disk for VM Disk volume 2.
