Remote monitoring Java applications

[Diancecht]

OK, let's go again with one of my strange questions.

Let's imagine that I have a have a Java application running on some machine.

What I'm trying to do is to develop some kind of monitoring software for that application. That software will connect to the remote machine where the java application is running, will get the information and show it to the client.

The information will be mainly about performance: memory used, number of allocated objects and that stuff.

My approaches so far is using the JMX or the JVMPI.

I was wondering if aynoed here faced an issue like this and could give me some advice on APIs, products or tecniques related to this.

Cheers,

Dian

I use JMX all the time for monitoring and controlling the runtime behaviour of remote applications. Its easy peasy and fairly light.

Thanks sedj, nice to know.

I have a question about this. I've overlooked the JMS specification and I still have a doubt. Do I need to change the monitorized software to make it run?

The idea is making a profiling application, so keeping the server code unchagned woulb be an excellent point.

JMS is message queue (MQ) software - different to JMX - but I'm guessing that was a typo ?

The easiest way to monitor an app using JMX is to code it into the app (by creating MBean interfaces, and then having your code to monitor implement the interface - thus exposing it to the JMX container).

But I believe it would be possible to create a non-invasive monitor using reflection to extract the relevant data at runtime, and then exposing that data through JMX. Though obviously, this would be trickier !

Yes, it was a typo, sorry.

So the fundament is re-coding. I think I'll try the hard way, let's see if it compenses.

Greetings Dian:

I've read your question about monitoring an application, rigth now I have the same problem, I need to monitorize an application, only to know what processes have been done, and who had done, can you tell me if you get the solution for this matter? so can you give me a clue for solving mine?

I don't much about JMX, but now I'm reading about it

Thanks a lot

I've almost forgotten this issue.

I finally gave it up, more important things came so it's still in the heap.

I'm afraid I can't tell you much more, Google will help you finding the documentation,

Cheers,
