That was taken care of by the IntelliJ plugin. I didn’t have to generate separate Tomcat startup. Using the plugin for my IDE, IntelliJ in my case, running JProfiler is even easier. This gave me a nice overview of where the request took the most time. I went for the CPU usage and could see the execution path. I could record memory usage and CPU usage. I attached the session to the listening process and it gave couple options. Then I run the server and it did wait till JProfiler connected to it. I had to select the application server home directory and the wizard generated a separate start up script for the application server to use with JPofiler. JProfiler was easy to set up and it walked me through a wizard where you can select the application server used to run the application. It can tell you which classes and methods are hit, but it will not show the flow through the application. It has default memory and CPU monitoring.

VisualVM is a resource profile tool that comes with JDK starting from 6 update 7. The application is deployed on Tomcat server. My setup is a Spring based application with a RESTful interface using the MongoDB as its data store. The layout of application flow should include classes and methods against time In order to make the right choice, I set up some minimum requirements that the profiler should meet: There are many Java profilers out there that could help me to figure out this problem, only the question was which one should I use?

In order to figure this out in more detail, I decided to do some profiling to see where the application was using most of its resources and how to tackle this problem. I did wonder, maybe the performance could be increased by altering the application’s logic or maybe the application had reached its limit and needed to be scaled up. However, in my case the performance decreased at a rate much higher than when compared to the increased load. It seems logical to think when increasing the load on the application, that the performance will decrease. Please correct me if I’m getting the picture wrong, or neglecting somehow any other relevant aspect of OFI.While maintaining one of our client’s applications I noticed some performance problems under higher load. ISSPROF is great to find out what is happening now and may require being monitored in the future. OFI is great to monitor and control what you already know to need monitoring. I have used both of them before, and feel that they address different aspects of the monitoring spectrum. While OFI serves an operations management purpose (I need to know WHEN a known service is running slower than expected/required and be informed of such), along with great operations automation features (through Rules, Alerts, SLA, Actions). In my opinion ISSPROF serves an “immediate” operational purpose (I need to know right now WHY a service is running slow), and as a means to accurately check for service performance bottlenecks while still in development stages.

Small footprint on IS (no DB required, no changes to services, no configuration on which services to profile… just install it and start profiling)Ĭompared to OFI it still lacks the fancy graphical interface, the statistical analysis features, and any notion of past/trends/deviations.

Ability to get the Java stack trace of any running service thread.

Profiling on running services and service invocation trees, while they are actually running on the IS, and not as aggregated statistical data.

CPU time metrics per service, and per service invocation tree (these are really useful for identifying IO bottlenecks as those don’t take up CPU time but consume time nonetheless).

Service invocation tree time metrics, and not only service-centric metrics (the time taken by a service may vary depending on the invocation path taken, and ISSPROF does show that).

However, the Wrightia IS Service Profiler (ISSPROF) provides a few other features not currently provided by OFI: OFI does provide some profiling capabilities for IS, and the ability to define Rules & Alerts over the service KPIs.
