Page last updated:
Follow the steps below to manage your App Autoscaling service instance.
Log in to the Apps Manager: Logging into the Apps Manager
Select a space containing an App Autoscaling service instance from the org dashboard or from the left navigation bar.
In the Services section of the space dashboard, under your App Autoscaling service instance name, click Manage.
Note: To access the Manage link for the app autoscaling service, you must have the role of Space Developer. See Managing User Accounts and Permissions Using the Apps Manager for help managing user roles.
By default, new autoscaling instances are paused. If paused, click Turn On to enable monitoring of your application and start the autoscaling process.
Click the clock icon on your Autoscaling dashboard.
In the Scheduling interface, create a new rule by editing the date and time fields and choosing values for the number of minimum and maximum instances. When finished, click Save. See the Rule Types section of this topic for more information.
After saving, the left side of the Scheduling interfaces shows your rule. Click your rule to edit it.
Edit your existing rule and click Save to save your changes.
In the left pane of the Scheduling interfaces, click the X for a rule to delete it.
Close the Scheduling interfaces to return to your Autoscaling dashboard. The Scheduling section of the Autoscaling dashboard displays the next occurring rule and summary information about your rules.
Scheduled scaling rules affect the minimum and maximum instance count values for your application. When the autoscaling service runs a scheduled scaling rule, it changes the Min and Max values of the instance count of your application to the values specified in the rule.
The autoscaling service runs a one-time scheduled scaling rule once only. After running a one-time scheduled scaling rule, the service removes the rule from the list of existing rules.
Note: You must schedule one-time rules to occur at a time in the future.
The autoscaling service runs a recurring scheduled scaling rule on a regular basis. You select one or more days of the week for a rule, and the autoscaling service runs the rule on those days every week.
Click pause for a particular rule to stop the autoscaling service from running that rule. Click play to resume running that rule.
Note: The autoscaling service does not run a recurring rule for the first time until the date specified in the rule.
The rule shown in the image below recurs every Monday and Friday at 4AM, starting on Friday, November 28, 2014. This rule changes the minimum number of instances of the app to 10 and the maximum to 20.
The rule shown in the image below recurs every Wednesday at 4AM, starting on Friday, November 28, 2014. This rule changes the minimum number of instances of the app to 1 and the maximum to 3.
Based on the two rules above, starting on Friday, November 28, 2014, the autoscaling service scales the minimum and maximum instance counts for the application as follows:
Every Monday, the autoscaling service scales the minimum up to 10 and the maximum to 20.
Every Wednesday, the autoscaling service scales the minimum down to 1 and the maximum to 3.
Every Friday, the autoscaling service scales the minimum back up to 10 and the maximum to 20.
