A Guide on Optimizing Microsoft Azure Applications Insights Telemetry Performance with Total Operation Duration Analysis

In today's constantly evolving global landscape, it's essential to monitor your business website's performance to gain insights into your clients' and users' preferences and get a complete view of its overall performance. With cloud migration becoming a popular strategy worldwide, organizations are extensively shifting their applications to the cloud to effectively utilize its capabilities and provide the best outcomes to end-users.

Azure Functions and Azure Monitor, both available in the Azure Cloud, offer enterprises a way to monitor the behavior and performance of Azure Functions. By integrating Azure Functions with Azure Application Insights, a component of Azure Monitor, businesses can achieve real-time monitoring and analysis of telemetry data from Azure Functions.

Significance of knowing an Overview of the Total Operation Duration

- Administrators can identify the areas of application that can be optimized once they are aware about the total operation duration. It helps them to detect performance barriers. E.g., By examining the load times for API requests or specific pages, administrators are able to give priority to areas that can be improved.

- Another decisive factor is to ensure that the application is able to meet the users’ expectations by offering apt responses. Administrators can achieve this by monitoring the total duration of load time. Often slow times can lead to decreased user engagement and dissatisfaction. Due to this, it is essential to monitor and improve load times to retain users and keep them engaged while using the app.

How does Microsoft Azure Monitor work?

Microsoft Azure Monitor gathers monitoring metrics from diverse sources – both on-prem and Azure cloud. Log data is sent to monitoring tools like Azure Monitor, Azure Automation, and Azure Security Center. The collected metrics are then consolidated and stored in a log data store that is optimized for both cost and performance. Microsoft Azure Monitor also has the ability to collect Sampling data, which involves analyzing a representative subset of data from a larger dataset. Sampling helps reduce the amount of data to be collected and analyzed while still providing accurate insights into the performance of functions.

Three types of Sampling options are available:

1. Adaptive Sampling

Adaptive Sampling adjusts the sampling rate of an application dynamically based on its workload. If the website experiences high activity, the sampling rate is automatically increased to capture more data, while low activity results in a decrease in the sampling rate to minimize data collection.

2. Fixed-rate Sampling

Fixed-rate Sampling approach collects the data at the fixed interval rate. Developers can set the interval rate of every 10 seconds of every 100 requests.

3. Ingestion Sampling

Ingestion Sampling takes place at the Application Insights service endpoint. Depending on the Sampling rate set, it discards unnecessary telemetry. Ingestion Sampling is like custom sampling where developers can define their sampling logic in Azure DevOps according to definite criteria or business requirements.

Sampling is essentially useful in scenarios where collecting and analyzing all the data from an application is not practical or feasible. Sampling is quite valuable in many Azure Monitor features, such as Application Insights, Log Analytics, and Metrics Explorer.

What are Microsoft Azure Application Insights?

Microsoft Azure Application Insights is a Microsoft solution and a component of Azure Monitor that provides real-time web application performance monitoring. It collects telemetry data such as error logs, performance metrics, and usage statistics, and its architecture is designed to ensure a smooth website performance and optimal user experience. It can be used for applications running on various platforms, including .NET, Node.js, Java, and Python, hosted either on-premises, in a hybrid environment, or in any public cloud. Additionally, Azure Application Insights seamlessly integrates with Azure DevOps and can connect with various development tools.

Microsoft Azure Functions provide in-built integration with Azure Application Insights. With the appropriate analysis of the telemetry data collected by Azure Application Insights, developers are able to achieve valuable insights into the behavior of the functions and identify opportunities.

To analyze the telemetry data in Azure Functions, the following steps can be carried out by developers:

1. Enable Application Insights Integration

To enable the Application Insights Integration, use the Azure Portal or add the Application Insights extension to the function app.

2. Collect Telemetry Data

Requests, exceptions, and traces are some of the telemetry data which is automatically collected by Azure Functions. Developers can also add custom telemetry data using Applications Insights SDK.

3. View Telemetry Data

To view Telemetry Data, use Azure Portal or tools like Power BI or Visual Studio.

4. Analyze Telemetry Data

Once the Telemetry Data is collected, developers can use various analysis tools available in Application Insights to gain knowledge about the behavioral patterns of the functions.

5. Take necessary action based on Insights

Depending on the insights gained from Telemetry Data analysis, developers can take actions to optimize their functions like tuning performance settings, refactoring code, or additional monitoring.

What is the Telemetry Total Operation Duration metric?

To measure the total time taken for an operation to complete, from the initiation to the end; the Telemetry Total Operation Duration metric was designed. It may include time taken for database queries, network requests, and any other processing necessary to complete the operation.

By constantly monitoring the Total Operation Duration metric, developers can identify the operations that are the longest to complete. Developers can take fitting measures to optimize them. To optimize the Total Operation Duration, they can optimize database queries, improve network performance, or re-architect parts of the application which are currently deterring the performance.

End Note

Microsoft Azure is a scalable cloud service to monitor resources both on-prem and in the cloud. Its Application Insights component detects anomalies and enhances the performance management of the website. With the effective monitoring of the Total Operation Duration metric, developers can take actions to improvise. If enterprises want to elevate their website performance management, they can integrate other tools like SAP and Salesforce.
