Application Performance Troubleshooting: Deep Dive Analysis with NETSCOUT

Imagine a situation: users are complaining about slow application performance, and application performance troubleshooting turns into an endless search for the guilty. Time is money, and every minute of service downtime hits the company’s reputation and profits. Traditional diagnostic methods often require access to servers, code, and databases, which is not always possible or convenient. NETSCOUT offers a solution that allows you to perform deep application diagnostics without having to delve into the application infrastructure. This allows you to quickly identify and fix problems, minimizing the impact on the business.

Why is deep application diagnostics so important?

In today’s world, applications are the nervous system of a business. They enable interaction with customers, automate processes, and support decision-making. But if an application is slow or unstable, it can lead to serious consequences:

• Customer loss: Slow operation or application errors lead to a negative user experience and customer churn to competitors.
• Reduced employee productivity: When employees spend time struggling with application problems, their productivity drops.
• Lost profits: Application downtime can lead to direct financial losses.
• Reputational risks: Application failures can damage a company’s reputation.

Effective application performance troubleshooting requires quick identification and resolution of problems before they start impacting the business. This requires tools that provide deep application diagnostics and allow you to quickly find the root cause of problems.

NETSCOUT: Deep application diagnostics without limitations

NETSCOUT offers a unique approach to application performance diagnostics based on network traffic analysis. This allows you to perform application code analysis through the network without requiring access to servers, code, or databases. The NETSCOUT solution provides:

• Real-time monitoring: Continuous monitoring of all transactions and interactions between application components.
• Automatic anomaly detection: Identifying deviations from normal behavior that may indicate performance or security issues.
• Root cause analysis: Quickly identify the root cause of problems such as slow database queries, code errors, or network issues.
• Analysis of slow SQL queries without database access: Identifying slow and inefficient SQL queries that can slow down the application.
• analysis of application errors: detailed analysis of errors occurring in applications for quick identification of causes and areas requiring correction.

How does it work?

NETSCOUT uses Adaptive Service Intelligence (ASI) technology to analyze network traffic and extract information about application performance. ASI allows you to:

• Decode network traffic: ASI decodes traffic at the level of application protocols, such as HTTP, HTTPS, SQL, etc.
• Extract performance metrics: ASI extracts performance metrics such as response time, request processing time, number of errors, etc.
• Create behavioral models: ASI creates models of normal application behavior, which are used to detect anomalies.

Thanks to ASI, NETSCOUT can provide deep analysis of application component interaction without requiring the installation of agents on servers or access to code. This makes it an ideal solution for environments where access to servers is limited or impossible.

Solving specific problems: why does the application return a 503 error

Imagine that users suddenly start receiving 503 errors when trying to access your application. Traditional diagnostic methods may require lengthy log analysis, access to servers and code. With NETSCOUT, you can quickly determine the cause of the problem:

1. Traffic monitoring: NETSCOUT shows a spike in 503 errors in real time.
2. Traffic analysis: NETSCOUT analyzes traffic and shows that the problem is caused by overloading one of the database servers.
3. SQL query details: NETSCOUT allows you to see exactly which SQL queries are causing the server to overload.
4. Troubleshooting: You optimize SQL queries, and the 503 error problem disappears.

This example demonstrates how NETSCOUT allows you to quickly identify and resolve application performance issues, minimizing the impact on the business.
