Unexpected Cost Using Azure Application Insights for VS Code Extension Telemetry? Here’s What You Need to Know

As a developer, you’re no stranger to the concept of telemetry. You’ve likely used it to track user behavior, monitor performance, and identify areas for improvement in your VS Code extensions. One popular choice for telemetry is Azure Application Insights, a powerful tool that provides valuable insights into your extension’s usage and behavior. However, have you ever noticed an unexpected spike in costs associated with using Application Insights? If so, you’re not alone.

What’s Causing the Unexpected Cost?

Before we dive into the solution, let’s first understand what might be causing the unexpected cost. There are several factors that can contribute to higher-than-expected costs when using Application Insights for telemetry:

• Data Ingestion Volume**: The amount of data ingested into Application Insights can have a significant impact on costs. If your extension is generating a large volume of telemetry data, you may be surprised by the costs associated with storing and processing that data.
• Data Retention Period**: The length of time you choose to retain your telemetry data also affects costs. A longer retention period means more data is stored, which translates to higher costs.

How to Avoid Unexpected Costs with Application Insights

Now that we’ve identified the potential causes of unexpected costs, let’s explore some strategies to help you avoid them:

Optimize Data Ingestion Volume

// Example of using sampling with the Azure Application Insights JavaScript SDK
import { AppInsights } from '@microsoft/applicationinsights-web';

const appInsights = new AppInsights({
  instrumentationKey: 'YOUR_INSTRUMENTATION_KEY',
  samplingPercentage: 10 // Sample 10% of telemetry data
});

Configure Data Retention Period

The data retention period also has a significant impact on costs. Here are some tips to help you configure the retention period wisely:

Monitor and Optimize Your Telemetry Data

Regularly monitoring and optimizing your telemetry data can help identify areas of improvement and reduce costs:

Pricing Plan	Data Ingestion Volume (per day)	Data Retention Period	Cost (estimated)
Free	1 GB	7 days	$0
Basic	100 GB	31 days	$2.30 per GB (above 1 GB)
Enterprise	Unlimited	Unlimited

Implement Cost-Effective Telemetry Strategies

Finally, implement cost-effective telemetry strategies to reduce costs without compromising the quality of your extension’s telemetry data:

// Example of using custom events with the Azure Application Insights JavaScript SDK
appInsights.trackEvent({
  name: 'Custom Event',
  properties: {
    category: 'Category',
    action: 'Action',
    label: 'Label'
  }
});

Conclusion

Unexpected costs associated with using Azure Application Insights for VS Code extension telemetry can be a concern for developers. However, by understanding the factors that contribute to higher costs and implementing strategies to optimize data ingestion volume, configure data retention periods, monitor and optimize telemetry data, and implement cost-effective telemetry strategies, you can reduce costs without compromising the quality of your extension’s telemetry data.

Remember, Azure Application Insights is a powerful tool that provides valuable insights into your extension’s usage and behavior. By using it wisely and efficiently, you can create a better user experience while keeping costs under control.
