Java In-Build Profiling and Monitoring Tool and Utility

Java code profiling and tuning are some of the major tasks for a Performance Engineer. Without knowing the performance bottleneck, it is difficult to predict the root cause. And, for knowing the bottleneck he must need a monitoring tool.  

Do you know there are a couple of in-built Java monitoring tools and utilities are available which makes a performance engineer's life easy?

If you are not aware then this article will be helpful for you.

Use these profiling and monitoring tools in your project and enhance your skill.

Future of Performance Monitoring

In the current world, Performance Monitoring as important as Performance Testing. Many big names like DynaTrace, AppDynamics are continuously working to improve the monitoring features in the APM tool. Even they succeed to make strong tools which are not only monitoring the performance of the system but providing the root cause analysis for the bottleneck (these are very basic features, but they are doing more than these). 

AppDynamics team has introduced AIOps concept in the tool and improved the AppDynamics features and add a feather in the cap. A video has been twitted by AppDynamics on 'Future of Performance Monitoring'. I would suggest to stream the video and understand where the performance testing world is going.

Types of Memory Leakage, Reasons and Resolutions

Memory leakage is one of the common bottlenecks found during performance testing. Ideally, endurance (also known as a soak) test is conducted to identify the memory leakage in the application. But sometimes the system fails due to memory issues even in the load test. In such a situation, there could be multiple reasons which make the servers out of memory. 

Today, I found a good document in which most common out of memory error types are listed out along with reasons and generic solutions. I would suggest to download and save this PDF because in future when you try to resolve the bottleneck related to memory issue then this document could be a key treasure for you.

Architectural understanding for Performance Engineering - By RadhaKrishna Prasad

Performance Engineering is growing day by day. Many IT companies whether they are service-based or product-based, are demanding for the resource who has knowledge of both performance testing as well as performance engineering. The practical knowledge of Performance Engineering is a must, but a strong building of Performance Engineering can be created over a solid base of theoretical knowledge. By the way, to learn the performance engineering 3 features are required:

1. Architectural understanding

2. Experience, to find the bottleneck

3. Deep knowledge, to resolve the issue by suggesting an optimized way.

Starting the first step, RadhaKrishna has shared an informative article which can help to understand the basic architecture of 3 tier application along with information like how to estimate workload modelling, how to scale the environment etc.?

1. Performance requirements - criteria that are absolutely non-negotiable due to contractual obligations, service level agreements or business needs. Only those criteria whose sub-par performance would unquestionably lead to a decision to delay a release are absolutely required.

2. Performance goals - criteria desired for release, but negotiable under certain circumstances. For instance, if a response time goal for a particular transaction is set at 3 seconds, but the actual response time is determined to be 3.3 seconds, it is likely stakeholders will choose to release the application and defer performance tuning of that transaction for a future release.

3. Performance testing objectives - items that add value to the team through the process of performance testing but are not intrinsically quantitative. For example, one objective might be to provide certain data to systems administrators to assist them in tuning systems under their purview. Another objective might be to determine peak application usage that the existing network can support.

The above content has been taken from a white paper "Get performance requirements right - think like a user" written by Scott Barber and published by Compuware. The reference document can be accessed via this link.
