How to view and analyze JMeter Result - J3
How to run test by JMeter - J2
How to install JMeter - J1
🧩 Pre-condition:
JMeter is openning
Test Plan is created with HTTP Request
Thread Group is active and request works
🛠 Steps by step:
Step 1: Thread Group → Add → Listener
Step 2: Choose one or more Listeners
View Results Tree
Summary Report
Aggregate Report
Graph Results
Step 4: Click the Start button to run the test
Step 5: After the test completes, view the results in each Listener
✅ Expected Result:
📌 For a well-performing system, you should aim for: Zero errors.
Average response time below 800ms (for APIs).
90% Line close to the average.
Stable throughput.
Low standard deviation. => These indicators help you understand not just whether your test passed, but also whether your system is fast, stable, and ready for production traffic.
Each Listener shows a different view
🔍 1. View Results Tree: Great for debugging and API testing
Status codes are correct (e.g., 200, 201, 204)
Response data should not be null/error
Error/Failure if timeout, connection refused, 401, 403
Response time should ideally be under 1000ms for a normal web/API service
🔍 2. Summary Report: Quick performance overview
A correct number of samples (matches the number of users × loops)
An average response time under 800–1000ms
A 0% error rate (meaning no requests failed)
A reasonable max response time, not too far from the average
High throughput, meaning the system can handle many requests per second => If the error rate is above 0%, you should look into the cause in the View Results Tree.
🔍 3. Aggregate Report: Detect performance spikes or instability
90% Line: 90% of your requests finished faster than this time. It should not be far from the average. A big gap might mean performance is inconsistent
Standard Deviation: This tells you how stable your response times are The lower, the better. High deviation means the system reacts differently under the same load — a sign of instability
Max response time: Should not go beyond 3–5 seconds for simple requests => If you see high deviation and a max response time far from the average, even when the error rate is 0%, it still indicates potential performance issues.
🔍 4. Graph Results (optional): Easy visual tracking of performance over time

Настройте Test Plan, активируйте Thread Group и подключите нужные Listener. Вы уже испытали, как точно измерить производительность ваших запросов?
Добавьте Listener, выбрав между View Results Tree, Summary Report, Aggregate Report и Graph Results. Эти инструменты показывают разные грани работы системы – от дебага до статистического анализа. Знаете ли вы, какой из них даст лучший обзор ошибок?
Тестируйте систему на ноль ошибок, с откликом под 800 мс и стабильным throughput. Каждый Listener детализирует разные аспекты: корректность статусов, скорость отклика и стабильность показателей. Готовы ли вы выявить потенциальные узкие места?
Используйте View Results Tree для проверки статуса кодов, Summary Report для быстрой оценки производительности и Aggregate Report для выявления скачков в стабильности. Даже Graph Results помогает увидеть динамику нагрузки в реальном времени. Смогли ли вы найти закономерности в поведении системы?
Не позволяйте нестабильности снизить ваш бизнес: протестируйте, проанализируйте и усовершенствуйте систему прямо сейчас – ваши данные не прощают ошибок!
