Tomcat 5.5 Monitoring with JDK 1.4 on Windows

由 独自空忆成欢 提交于 2019-12-08 07:59:53
问题 According to this documentation http://tomcat.apache.org/tomcat-5.5-doc/monitoring.html#Enabling_JMX_Remote it should be possible to remotely Monitor a Tomcat 5.5 Server running on a JDK 1.4 but after searching all over the web and trying multiple OSs I still am no further than on day one. My results thus far are. Settign up Tomcat with the standard -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=%my.jmx.port% -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management

Multiple Java Applications using JMX

由 筅森魡賤 提交于 2019-12-08 07:53:18
问题 I'm very new to JMX, and what I try to achieve is the following: I want to use JMX for monitoring multiple instances of the same Java-Application. The problem is, that this application might be run multiple times at the same time. I need the possibility to monitor the JMX values from another (remote) host. Example Java-Application: public class Test { public static void main(String[] args) { while(true) { try { Thread.sleep(1000); System.out.println("I'm running"); } catch

How to query the number of active sessions with JBoss Wildfly?

由 偶尔善良 提交于 2019-12-08 06:46:15
问题 We used to query the active session count by using the following code up to JBoss 7: ObjectName name = new ObjectName(jboss.web:type=Manager,path=/MyWebApp,host=default-host); MBeanServer jboss = MBeanServerLocator.locateJBoss(); this.sessions = new Long((Integer) jboss.getAttribute(name, "activeSessions")); That no longer works with JBoss Wildfly. I can't really find the proper documentation to access the same information with the current version of JBoss AS. I've come across some links like

How to access dynamicmbeans from a jmx client

由 馋奶兔 提交于 2019-12-08 05:34:01
问题 I am writing some test cases for the JMX interface in our product. I can access attributes from standard MBeans (following sun tutorial). However, I don't seem to be able to access dynamic MBeans. The attributes are fully (readable/writable) from JConsole. JMXConnector jmxc = getJMXConnector(); // Takes care of our connection MBeanServerConnection mbsc = jmxc.getMBeanServerConnection(); ObjectName mbeanName = new ObjectName("com.xyz.prodname:type=LogManager"); // Up to this point, the logic

问题 I run Tomcat8 using JDK8 on Centos6. I enable JMX using the following options: CATALINA_OPTS="${CATALINA_OPTS} -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9123 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.local.only=true" Unfortunately, when I check what ports are opened I discover that these ports listen to all IP: netstat -plunt | grep java Proto Recv-Q Send-Q Local Address Foreign Address

Insert MBean interceptor

由 五迷三道 提交于 2019-12-08 04:28:17
问题 I am working in a java project which implements MBeans and my need is to intercept MBean and change/add their properties before registry. Example : domainName:name=myMBean --> domainName:name=myMBean1,type=myType I found this link which presents how to apply an interceptor other then default interceptor but I have no idea to how do that in code. Thanks in advance. 回答1: Once you register the bean obviously it is too late. The easiest thing to do is to change how the registration is done. If

JMX Port dynamic allocation

由 允我心安 提交于 2019-12-07 07:56:43
问题 I have 16 Java processes with the same main method and arguments running on one machine. I wish to monitor these remotely thru JConsole. Hard coding port numbers like -Dcom.sun.management.jmxremote.port=5000 won't work because these processes are using same configuration and they can't work with same port. Is it possible for the JVM to select a different port dynamically for each of the 16 processes? 回答1: Using RMI Connector might be the way as you may specify URL of your agent. In case you'd
