Dear All,
The nlgug (http://www.nlgug.org/) had invited me and last night I gave a talk about monitoring Grails applications using Java-monitor. Nlgug is a small but fast growing community of Dutch Groovy and Grails users.
The main point of my talk was to show that because of the foundation of Grails, it is as easily monitored as any other Java web application.
The nlgug-ers were (well, seemed) interested and asked some good questions. One person asked if Java-monitor could visualise what resources are being used by what web application. This question also pops up on the Tomcat users mailing list every now and then. The answer is no: Java-monitor cannot see what resources are being used for. My normal advise is to simply deploy each web application in its own servlet container. This makes resource tracking easy and isolates problematic webapps from the rest.
I set a challenge to make it even easier to monitor Grails applications. Could someone with in-depth knowledge of Grails make Java-monitor into a Grails plug-in? I'll send you a cool gadget in return. :-)
I tried to do a demo of the Hibernate stats plugin for Grails (http://grails.org/plugin/hibernate-stats), but I could not get it to work. Can anyone help me with that, please?
Some members in the audience also have experience making Java applications connect through proxy servers and I hope they'll share that knowledge so we can make Java-monitor's probe better in such environments.
E-Id! (http://www.e-id.nl/) hosted the event and provided food. Thanks guys.
Here are the slides: http://java-monitor.com/presentations/nlgug-aug-2009.swf
