Cause

Optimization hours are evaluated as continuous time ranges. If you configure one range that starts on one day and ends on another, Flexera treats the entire period between those times as valid for Spot optimization.

For example, configuring optimization hours from Monday at 09:00 to Friday at 20:00 allows Spot reversion at any time during that entire span, including evenings on Monday through Thursday.

Solution

Configure separate optimization windows for each day instead of a single multi‑day range.

1. Open the stateful node configuration

   In the Flexera console, go to Elastigroup > Stateful nodes, select the node, and then select Actions > Edit configuration.
   
   

2. Open availability settings

   Go to Compute > Availability settings.
   
   

3. Configure custom optimization hours

   Under Continuous optimization, select Custom.
   
   

4. Define daily optimization windows

   Add a separate time window for each day you want Spot optimization to occur.

   Example configuration for Monday through Friday, from 09:00 to 20:00:

   • Monday: 09:00 to 20:00

   • Tuesday: 09:00 to 20:00

   • Wednesday: 09:00 to 20:00

   • Thursday: 09:00 to 20:00

   • Friday: 09:00 to 20:00

   Each day must have its own start and end time.
   
   

5. Save the configuration

   Save and apply the changes.
