glassfish v3 throttling

Hello,
How can I throttle requests per ip, say, max 10 requests per ip, or rather ip/useragent when I am using glassfish v3? I though grizzly had some built in mechanisms for that, but I could not figure out how to do it.

Hello Oleksiy,
I am up to the challenge but I have no idea where to start. What is an interceptor, is it something like filter. The reason where I came up with this throttle thing is some people are attacking my glassfish, like sending 2000 requests per second, and i get an OOM and my glassfish crashes. Best.

Salut,
which GF version are you using? Cam Bazz wrote: > Hello Oleksiy, > > I am up to the challenge but I have no idea where to start.

Oh! Can you share the server.log? The Interceptor API is defined here: * http://is.gd/4Euml Mainly, this APi gets called after the request headers has been parsed. That might be too late for you so that's why I would like to see some stack trace I can help. It might be better to close connection as soon as you accept them. In that case, you would like to extends the TCPSelectorHandler: * http://is.gd/4EuBO Specifically the onAccept method * http://is.gd/4EuDV Now if we go that route I will need to do some work to allow you to configure GF to use your TCPSelectorHandler. That's simple to do.

Hello Jean Francois,
I am using GlassFish v3 (build 47.4) I also made the unfortunate mistake of using this in production server.... :) Unfortunately, there is nothing in server log. It just says out-of-memory error, then the server goes blind. However, I do have a heap dump that I got with jmap, and now I am trying to open it with jmap, but it is a 4gb heap dump, and i have 8gb of mem in my box, and 8gb is not enough. I specified -mx12G and of course it is running for 3 days now, but did not start the jhat server yet. but still waiting. I will read the api documents, and rewrite a mail later on.

If you can share the heap dump (or open port 7000) I'm sure I can help with this.

Hello Jean,
The heap map is 4GB. I was not able to jhat it. (my computer only has 8gb or ram). when I specify for the jhat to use more then 8gb, it goes on virtual memory, and it does not finish to open port 7000. I will be migrating to b70 pretty soon. Best.

Thanks for the update. I would really like to make sure v3 FCS doesn't suffer the problem. If you see such thing, I would like to find a way to introspect you heap.bin.
