Autoscale Configuration Fields
The following tables describe each autoscale configuration field in detail. For information on creating an autoscale configuration, see Creating an Autoscale Configuration.
Fields for both Vertical and Horizontal Autoscaling
Field | Description |
---|---|
Autoscale configuration name |
Enter a name for this configuration. |
Cluster admin password |
Enter the admin password for the cluster. (You assign an admin password when you create a cluster.) |
Node type |
Select the type of node. The available options are as follows:
|
Autoscale type |
The available options are as follows:
|
Trigger type |
Begins the autoscale based on the metrics of the nodes provided when configuring the autoscale configuration schedule. |
Performance Metrics |
Begins the autoscale based on the metrics of the nodes provided when configuring the autoscale configuration schedule. This is dependant on the metric trigger type. Performance metrics include:
|
Fields for Vertical Autoscaling
Field | Description |
---|---|
Scale-up rule |
This field appears when you select the vertical autoscale type and metrics for the trigger type. The scale-up rule sets the conditions for scaling up the cluster (use a larger compute shape). If you selected CPU utilization in the Performance metrics field, enter the following details:
If you selected Memory utilization in the Performance metrics field, enter the following details:
If you selected a Flex shape, then also specify the following details:
For example, if the scale-up rule is:
|
Scale-down rule |
This field appears when you select the vertical autoscale type and metrics for the trigger type. The scale-down rule sets the conditions for scaling down the cluster (use a smaller compute shape). If you selected CPU utilization in the Performance metrics field, enter the following details:
If you selected Memory utilization in the Performance metrics field, enter the following details:
If you selected a Flex shape, then also specify the following details:
For example, if the scale-down rule is:
If you selected Memory utilization in the Performance metrics field, enter the following details: |
Scheduled-based vertical condition | This field appears when you select scheduled-based vertical autoscale type and schedule for the trigger type. For schedule-based vertical autoscaling, enter the following details:
For example, if the schedule-based Vertical condition is:
In the example, the first trigger is set for 9:00 a.m. with a target shape of VM.Standard.2.8. The second trigger is set for 4:00 p.m. with a target shape of VM.Standard.2.4. |
Fields for Horizontal Autoscaling
Field | Description |
---|---|
Scale-out rule | This field appears when you select the horizontal autoscale type and metrics for the trigger type. The scale-out rule sets the conditions for scaling out the cluster (add cluster nodes). Note: Horizontal autoscaling applies only to compute only worker nodes. If you selected CPU utilization in the Performance metrics field, enter the following details:
If you selected Memory utilization in the Performance metrics field, enter the following details:
|
Scale-in rule | This field appears when you select the horizontal autoscale type and metrics for the trigger type. Note: Horizontal autoscaling applies only to compute only worker nodes. The scale-in rule sets the conditions for scaling in the cluster (use a smaller compute shape).
If you selected Memory utilization in the Performance metrics field, enter the following details:
|
Conditions | This field appears when you select scheduled-based horizontal autoscale type and schedule for the trigger type. Note: Scheduled-based horizontal autoscaling applies only to compute only worker nodes. For schedule-based horizontal autoscaling, enter the following details:
For example, if the schedule-based Horizontal condition is:
In this example, 10 nodes are available between 9:00 a.m. and 4:00 p.m. on the specified days. However, when the time reaches 4:00 p.m. the nodes drop to one and remain at one until another trigger is reached. |
