Java-monitor now allows you to share your Java application server statistics with your friends and co-workers. They can look over your shoulder at the data for a particularly troublesome host. Or they may keep an eye on how things run when you are away on a business trip.
PS. In case you don't know: Java-monitor is the free, on-line monitoring tool for Java application servers. Receive an e-mail when your server goes off-line. Tune your memory allocation. Java-monitor supports Glassfish, Tomcat, JBoss, Jetty, Openfire and lots more. Try the live demo of this service on http://java-monitor.com/livedemo.html
