Autoscaling-over-time Dashboard

Leverage scaling-over-time dashboarding for your application autoscaling with Azure Durable Functions. 📊

What does it provide?

Use App Instances metrics to visualise how the applications in your platform are scaling.

Here are a few more examples:

Application instances by name

Application instances per runtime

Application instances per Kubernetes namespace

Learn more about the available dimensions below.

How does it work?

For every application in your platform, a durable entity is available that allows you to:

• Receive CloudEvents for Azure Monitor Autoscale events (based on Azure Event Grid adapter for Azure Monitor Autoscale)
• Receive CloudEvents for Kubernetes application events (based on Kubernetes Event Grid Bridge)
• Automatically report current instance count every 5 minutes with various dimensions
• Get the current instance count for a given app

Here's a high-level overview:

Gain deeper insights with dimensions

Want to have a more detailed overview? Use the various dimensions that are provided:

• For Kubernetes applications, we provide:

  • AppName - Name of the deployment in the cluster
  • Namespace - Name of the Kubernetes namespace
  • Runtime - Fixed to Kubernets

• For generic applications scaled with Azure Monitor, we provide:

  • AppName - Name of the Azure resource
  • SubscriptionId - Name of the Azure subscription
  • ResourceGroup - Name of the Azure resource group
  • Region - Name of the Azure region
  • Runtime - Name or type of Azure service hosting your application, for example Azure App Service
