I am running several applications in IBM WebSphere Application Server (WAS) 7. The applications can be managed from the WAS console: http://{myserver}:9060/ibm/console/login.do
I am able to monitor those deployed applications with JVisualVM. How can I monitor the WAS console with JVisualVM. Does it have a default JMX port?

I have deployed one java application in tomcat server. And tomcat server was configured as windows service in one of my VMs.
Our VMs are windows servers with 64GB RAM and 8 core 2.4 GHz Intel Xeon Processors.
Below are the software details and JVM args configured.
JDK 1.7.0_67
Tomcat 7.0.90
JVM args for Tomcat :
-Xms2g -Xmx40g -XX:PermSize=1g -XX:MaxPermSize=2g
But still getting this issue, could you please any one help.
You can enable JMX (which is a technology to monitor java applications) by adding the -Dcom.sun.management ..... jvm options on the startup script and connect your application via JConsole with JTop Plugin which shows the top CPU consuming threads. Refer :https://arnhem.luminis.eu/top-threads-plugin-for-jconsole/
I am using tomcat 7.0.8 in windows server 2008 remote machine(using it a server machine). Where I have hosted my java webapp running on port 80.
I start the tomcat server by running the startup.batch file. The issue is that the tomcat server shutdowns automatically whenever logoff from remote machine and not using the application for sometime like 30-40mins. I even disabled the tomcat shutdown 8005 but still the problem persists.
Please help me to solve this.
Thank you.
in my local machine I am running an web application in JBoss server. I am using JVisual VM for profiling my application. When I am trying to point/connect to JBoss with JVisual VM, My application is getting tremendously slow or its getting down(not working any more).
I want to do instrumentation profiling to get the actual memory usage for various objects.
OS: Windows 7 Enterprise
Processor: Core 2 Duo #3.00GHz 3.00GHz
RAM: 4.00 GB
Did you use the JBoss client JAR:
jvisualvm.exe -cp:a c:\wildfly-8.1.0.Final\bin\client\jboss-client.jar
You will need to modify the JVM security policy:
grant codebase "file:${java.home}/../lib/tools.jar" {
permission java.security.AllPermission;
};
jstatd -J-Djava.security.policy=security.policy
use the add-user.sh script to add a Management user.
Add a Remote Host in VisualVM and use a JMX Connection with the Management user created above.
Full details on how to setup Visual VM: http://www.mastertheboss.com/jboss-server/wildfly-8/monitoring-wildfly-using-visualvm
As you can see, there's the new instructions:
https://docs.jboss.org/author/display/AS71/JMX+subsystem+configuration
And the old RMI instructions:
https://docs.jboss.org/author/pages/viewpage.action?pageId=21627109
I can get the new instructions working, but we use nagios, which only allows checking JMX via RMI, so I need to get RMI JMX working.
Does anyone have a solution for this?
I can't use the old instructions because it says <jmx-connector> is no longer supported.
I've added the following to my JAVA_OPTS on JBoss startup:
JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=12345 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false" -Djava.util.logging.manager=org.jboss.logmanager.LogManager -Dorg.jboss.logging.Logger.pluginClass=org.jboss.logging.logmanager.LoggerPluginImpl -Djava.rmi.server.hostname=10.20.2.50
but i can't get jconsole to connect to service:jmx:rmi:///jndi/rmi://10.20.2.50:12345/jmxrmi
(PS. If anyone with redhat paywall access could report back on the answer here: https://access.redhat.com/solutions/263763 that would be swell :P)
To connect to JMX the URL entered should be in the format
service:jmx:remoting-jmx://{host_name}:{port}
Standalone mode
where {port} is the native management interface of the AS7 installation being monitored (default=9999).
Domain mode
where {port} is the JMX subsystem interface of the AS7 installation being monitored (first server=4447, port-offset=150 next server).
<subsystem xmlns="urn:jboss:domain:jmx:1.1">
<show-model value="true"/>
<remoting-connector use-management-endpoint="false"/>
</subsystem>
Both modes
Outside localhost you have to set -Djboss.bind.address.management or inside xml (standalone.xml / host.xml).
Once connected the capabilities provided by jconsole can be used as normal.
Authentication
The connector is making use of JBoss Remoting to communicate with the server, for this reason the exact same authentication mechanisms as are used by the CLI will apply here.
Local
For processes running local to the AS7 installation we support a local authentication mechanism which allows clients to verify their identity by sharing a token on the filesystem with the server - this mechanism runs silently without any further user interaction required.
Username / Password
Where local authentication is not possible such as if the client is running as a different user than the AS7 process or is running on a remote installation by default the next mechanism to be used is username / password based. Where this mechanism is used the username and password of a user in the ManagementRealm if using the default management connector (port 9999) or in the ApplicationRealm if using the remoting connector (port 4447) should be supplied in the boxes on the 'New Connection' screen before the 'Connect' button is clicked.
The $JBOSS_HOME/bin/add-user.sh (Linux) or $JBOSS_HOME/bin/add-user.bat (Windows) scripts can be used to add these users. Make sure to choose between Management User and ManagementRealm vs Application User and ApplicationRealm depending on whether you're using the default management connector or the remoting connector (usually used with domain mode or when connecting remotely).
Necessary libraries to connect JMX over JBoss Remoting
The JMX MBeanServer is accessible using JBoss Remoting through the management connection. Therefore, it is necessary to add the following libaries from the modules directory of the EAP6 / AS7 distribution to the classpath of the monitoring application:
org/jboss/remoting3/remoting-jmx
org/jboss/remoting3
org/jboss/logging
org/jboss/xnio
org/jboss/xnio/nio
org/jboss/sasl
org/jboss/marshalling
org/jboss/marshalling/river

EDIT:
JBoss EAP 5 supports JMX monitoring using RMI, where JBoss EAP 6 does not. EAP 6 uses “remoting-jmx” instead of “rmi”.
You should look for another solution, as SNMP, or proper plugin for nagios
See:
JVM monitoring via SNMP of JBoss EAP 6 worker nodes with pnp4nagios Template
Jboss SAR MBean and Perl plug-in for Nagios compatible with Jboss 7.1.1
I am trying to deploy the hawtio-default-offline-1.3.1.war (into JBoss EAP 6.2) and I see this message in the logs:
10:16:07,988 WARN [io.hawt.jvm.local.JVMList] (ServerService Thread Pool -- 65) Local JVM discovery disabled as this JVM cannot access com.sun.tools.attach.VirtualMachine due to: com/sun/tools/attach/VirtualMachine
So I don't have a local tab when I start up hawtio. Is this OK? This is my local Windows laptop and I am deploying the hawtio WAR alongside my app WAR and I am launching it using the JBoss bat file. I do a jps and I can see the JBoss server running.
Appreciate any pointers, thanks!
Yes this is okay, the WARNING is only about the connect plugin, not being able to use the local discovery. You can always use remote discovery, also to connect to local.
But if you only need that hawtio application deployed in your EAP to manage and monitor whats running in the same JVM then this is no problem.
There is also a FAQ at hawtio about related to this.
