Event Operations

This topic describes how to add and manage scheduled event and recurring event for application scaling from the Smart Scaler management console.

Non Recurring Event

warning

For event scaling with Smart Scaler agent versions 2.9.28 or earlier, each application deployment in a namespace must have its own configured HPA. Without an individual HPA, event scaling fails.

However, starting with Smart Scaler agent versions 2.9.29 and later, event scaling no longer requires an individual HPA for each application deployment.

Add an Event

To add an event:

1. Go to CPU Scaling on the left sidebar and click Events from the menu.

   

2. On the Events page, click the Add Event button to add a new event.

   

3. On the Add Events page, enter the following details:

   1. Enter the name of the event in the Event Name text box.

   2. Under Event Details, enter the duration of an event.

      • Set the Start Date and Start Time of the event.
      • Set the End Date and End Time of the event.

   3. Select Does not repeat for a non-recurring event.

   4. Enter the number of hours in the Cooldown Period text box. It is the cooling period to handle the overhead incoming traffic after the event ends. The default value is one hour.

   5. Set the color from the Event Color drop-down list. The default color is green.

   6. Enter a short description to describe the event in the Event Description text box.

   7. (Optional) Enter a tag that would serve as a label to identify this event in the Tags text box. For example, add the tag sales for the sales event.

   8. Under Application Scaling Details, select the following:

      1. From the Select Application drop-down list, choose your application. For example, new-boutique is the sample application.

         

      2. Under the Choose Locations drop-down list, select the cluster. For example, select the in-cluster cluster where the new-boutique application is installed and select the value 3x for the projected increase in users. The value 3x is selected based on the expected incoming traffic at the time of the event.
