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
