Performance Monitoring Tools

2002-03-12 Thread Cugier (extern) 

Hello,

we are planning to perform some load tests against our application (Servlet,
JSP and EJBs). We have found some tools that will create the load on the
server and will monitor the response times. But we haven't found anything
that can be used to monitor Orion's behaviour during the test. What we want
to monitor is the memory consumption, CPU usage, Sessions etc. 
What is important is that we can record what we monitor so we will be able
to look at the resutls of the test later.

Does anyone has a recommendation for a tool that we can use?

Thanks

Peter

Hello. I have to do the same tests.

Can you please tell me about the loading test tools that you've found.

Thanks in advance.

Optimizeit was quite useful to me.
Cpu Usage, Object count, Memory usage, Garbage Collector activity.  Also 
tracked the amount of time spent in each function call.

Hi Jorge.

For generating the load, I have found both Siege and Grinder to be 
effective.  Not fancy, but definately effective.

Although it might sound strange I do not believe in low level tools such as
OptimzeIt on EJB level - first stage. Usually you end up using a component
based framework which might be distributed and EJB overhead just changes
results significantly. We switched to a simple set of classes which measure
response time on component level and watch it under load. In most cases we
are able to locate our hot spots easily. I can not release these classes to
public - just think about something which allows you to mark the beginning
and the end of a transaction, measure the time in between - and cumulate.

Hope this helps,
Jens
