# Scale Thresholds

Scale Thresholds are pre-configured settings for auto-scaling Instances. When adding auto-scaling to an instance, existing Scale Thresholds can be selected to determine auto-scaling rules.

## Creating Scale Thresholds

### Procedure

1. Navigate to Library > Automation > Scale Thresholds
2. Select + ADD
3. Populate the following:

### Results

NAME
:   Name of the Scale Threshold

AUTO UPSCALE
:   Enable to automatically upscale per Scale Threshold specifications

AUTO DOWNSCALE
:   Enable to automatically downscale per Scale Threshold specifications

MIN COUNT
:   Minimum node count for Instance. Auto-scaling will not downscale below MIN COUNT, and will auto upscale if the MIN COUNT is not met)

MAX COUNT
:   Maximum node count for Instance. Auto-scaling will not upscale past MAX COUNT, and will auto downscale if MAX COUNT is exceeded.

ENABLE MEMORY THRESHOLD
:   Check to set auto-scaling by specified memory utilization threshold (%)

MIN MEMORY
:   Enter MIN MEMORY % for triggering downscaling.

MAX MEMORY
:   Enter MAX MEMORY % for triggering upscaling.

ENABLE DISK THRESHOLD
:   Check to set auto-scaling by specified disk utilization threshold (%)

MIN DISK
:   Enter MIN DISK % for triggering downscaling.

MAX DISK
:   Enter MAX DISK % for triggering upscaling.

ENABLE CPU THRESHOLD
:   Check to set auto-scaling by specified overall CPU utilization threshold (%)

MIN CPU
:   Enter MIN CPU % for triggering downscaling.

MAX CPU
:   Enter MAX CPU % for triggering upscaling.
