Logic Apps Standard Autoscaling behavior

Question

Hi,

Is there any way to monitor the autoscaling decisions taken by Azure Logic Apps Standard? It would be nice to get more information on what prompted the Autoscaler to take a particular decision at a point in time and scale out the number of instances. That would help us optimize our Logic App Workflows to optimize the spend on instance counts.

Thanks.

Hello,

Welcome to Microsoft Q&A,

While Azure provides tools to monitor scaling activities, obtaining detailed insights into the specific triggers for scaling actions requires a combination of configurations and monitoring strategies.

1. Enable Diagnostic Logging for Autoscale: Autoscale diagnostics documentation.

Azure Monitor allows you to capture detailed logs related to autoscaling activities. You can collect logs that provide insights into scaling decisions by enabling diagnostic settings.

• Autoscale Evaluations: Logs related to the evaluation of autoscale rules.
• Autoscale Scale Actions: Logs detailing each scaling event.

Steps to Enable Diagnostic Logging:

1. Navigate to your Logic App's Autoscale settings in the Azure Portal.
2. Click on the Diagnostics settings tab.
3. Add a new diagnostic setting and select the log categories you wish to capture.
4. Choose a destination for the logs, such as a Log Analytics workspace or Azure Storage account.

2. Utilize Monitoring Dashboards: Logic Apps Standard Monitoring Dashboards.

Azure provides monitoring dashboards tailored for Logic Apps Standard, offering visual insights into workflow performance and scaling activities.
