Is it possible to measure the performance or Profile an application without using an IDE

[Ravi Kiran Va]

Hi ,

Our application is an .ear application . We are not using any IDE for development .just using EditPlus and we are using Weblogic11g as our server .

I have seen a lot of tools for profiling while googling but they work only in combination of an IDE only .

So please let me know is there anyway or tool so that i can measure the performance of my application as there is no IDE.

Thanks in advance , waiting for your suggestions.

Open source JAmon is a good place to start.

This site reviews a bunch of profilers

Also you can embed simple timing data collection based on the standard Java library method - System.currentTimeMillis().

You could also try adding the -Xprof JVM option to the command line. The output takes a little bit of effort to get used to, but it can be handy in some cases.

jamon let's you monitor servlets/jsp's, sql, and ejb's without chaning your code.

Thank you very much .

Atlast i found out that only Jamon is the only solution for me now .

But i am thinking about its learning curve again i need t learn its API for profiling.

There isn't much of an api. You can monitor jdbc, ejb's and servlets via configuration of standard files. Post any questions you have on the jamon forum and I will answer them.

Simply install the jamon jar at the server level of jboss. Install the jamon war (so you can view statistics).

Here are steps how you can get jamon working. I would pick one of them so you can get the hang of what the tool can do...

* jdbc - http://jamonapi.sourceforge.net/#WhatsNew22
* servlet filter or server valve - http://jamonapi.sourceforge.net/http_monitoring.html
* ejb's - http://jamonapi.sourceforge.net/#ejbmonitoring
* interface monitoring - http://jamonapi.sourceforge.net/#monitoringinterfaces
* log4j - http://jamonapi.sourceforge.net/log4j_jamonappender.html

If you choose to monitor your code directly too you could use AOP so you don't have to change code, or you can use the following coding style. The downside of the following approach is that you would have to change your code.

   
import com.jamonapi.*;
....

Monitor mon=MonitorFactory.start("yourLabel");

try {
...your Code...
} finally {
  mon.stop():
}

 

The "yourLabel" monitor will now be viewable in the "jamon.war" file.

Thank you steve very much for your time .Certainly need your help on this .

I will allocate all my sunday to Jamon API , and work on that.
