Also I would like to log the FreeMemory over the time, which could be done in the groovy script as well. When using the jmx console with the browser I can show the wanted value as can be done with executing twiddle. I tried quite a few code snippets from the internet and tried different permutation of URL syntax import java.lang.management.* import javax.management.ObjectName import javax.management.remote.JMXConnectorFactory as JmxFactory import javax.management.remote.JMXServiceURL as JmxUrl def serverUrl = "service:jmx:rmi:///jndi/rmi://vm-appsfs4p:1099/jmxrmi" String beanName = "jboss.system:type=ServerInfo" def server = JmxFactory.connect(new JmxUrl(serverUrl)).MBeanServerConnection def mbean = new GroovyMBean(server, beanName) println "Connected to:\n$dataSystem\n" println mbean.FreeMemory; What am I doing wrong? Please be kind as those are my first experiments in this area. I'd be happy if someone could help me with this, thanks in advance for your help Take care Andreas -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/609267#609267] Start a new discussion in JMX Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
