AW: Detect tomcat problems with a custom java reporting apps?

Yes, I am using this already. But there is some vital functionality missing. When an java.lang.outOf.MemoryException happens I won't get an alert unless I happen to be using lambda at the moment. So what we have at hand is a 'Schrödinger Cat' situation. I need to monitor the jmx control layer an

Re: Detect tomcat problems with a custom java reporting apps?

I'm not sure that after something "bad" happens you can access the server at all. An OutOfMemory or an AllThreadsBusy Exception normally lead to a non-responding tomcat. The best thing you could do is monitoring the logs with a separate script on the same machine and send mails on failure imho. r

Thanks for all your help and I have gotten it to work. It seems to be, however, dependant on the name it is being access by. I was hoping that I could just put 127.0.0.1 in there and then it would only accept connections from the local machine. It turns out that doing this only accepts connectio

AW: Detect tomcat problems with a custom java reporting apps?

You are right Leon. I just did a field test on our test server. The perm gen space is relatively small on that machine. So opened a lot sessions and did a lot of XSLT/FOP/Excel generation. Thus the perm gen space was spent very fast. I monitored this with lambda. In the end the server did not resp

Re: Restricting access to localhost for an HTTP connector - Email has different SMTP TO: and MIME TO: fields in the email addresses

I think the address tag will accept a regular expression. So you could put a negative 127.0.01 address entry in there. I am not good at regular expressions so google them. On 6/12/06, Mark Claassen <[EMAIL PROTECTED]> wrote: Thanks for all your help and I have gotten it to work. It seems to

Re: Restricting access to localhost for an HTTP connector - Email has different SMTP TO: and MIME TO: fields in the email addresses

@Mark, as Peter wrote, have a look in /etc/hosts. It probably looks like 127.0.0.1 localhost 192.168.0.2 testmachine.domain.com testmachine You should change this to 127.0.0.1 localhost testmachine 192.168.0.2 testmachine.domain.com Just be careful if you are using Solar

Re: Detect tomcat problems with a custom java reporting apps?

I think you need a multilayer system :-) 1) a http-client app which simply calls the same simple servlet (simply writing "available" in the response or something like this) each 10 seconds and check if the server replies at all. 2) monitor cpu load on the machine. If the idle time is 100% the to

We do have something similar to your first example. > 127.0.0.1 localhost > 192.168.0.2 testmachine.domain.com testmachine So we can probably move testmachine like you did. But does this mean that accesses by "testmachine.domain.com" will not comply? I was just hoping that the restrictio

Re: Restricting access to localhost for an HTTP connector - Email has different SMTP TO: and MIME TO: fields in the email addresses

The configuration in the connector is so that java know on which interface to 'BIND' to on the machine. Do a netstat -anp |grep LISTEN on your machine. This shows which interface which processes are bound to. The only process (generally speaking) that can connect to 127.0.0.1 is

Re: Restricting access to localhost for an HTTP connector - Email has different SMTP TO: and MIME TO: fields in the email addresses

It is restricted based on IP, not name. The name you give in the browser is resolved to an IP address via host file and/or DNS before making the request. What you really seem to be looking for is the remote address valve which allows/denies access based on the client's IP address. See http:

Re: Memory Profiling Strategy???

Also look at the memory useage of your servlet code, jsps, etc., ... Take a look at the objects you create and see if they are being dereferenced as you'd expect. Tomcat recycles certain instance objects (like servlets) instead of creating/destroying them per requests for performance reasons.
