I've deployed some Managed Beans on WebSphere 6.1 and I've managed to invoke them through a standalone client, but when I try to use the application "jconsole" distributed with the standard JDK can can't make it works. Has anyone achieved to connect the jconsole with WAS 6.1? IBM WebSphere 6.1 it's supossed to support JSR 160 JavaTM Ma...
Hey all. Newbie question time. I'm trying to setup JMXQuery to connect to my MBean, so far this is what I got. java -classpath jmxquery org.nagios.JMXQuery -U service:jmx:rmi:///jndi/rmi://localhost:8004/jmxrmi -O java.lang:type=Memory -A "NonHeapMemoryUsage" Here's what I get. JMX CRITICAL Authentication failed! Credentials required ...
I am trying to set up JBoss 4.2.2 and JConsole for remote monitoring. As per many of the how-to's I have found on the web to do this you need to enable jmxremote by setting the following options in run.conf. (I realize the other two opts disable authentication) JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote.port=11099" JAVA_OPTS...
It seems that I've never got this to work in the past. Currently, I KNOW it doesn't work. But we start up our Java process: -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=6002 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false I can telnet to the port, and "something is ther...
Hi all, I'm searching free tools for monitor tomcat (traffic, memory usage, threads, requests, CPU, logs,...). I'm currently using lambdaprobe on Tomcat 5.5.x, but it seems that is no more developed (or not? the site lambdaprobe.org is always down for me...). Has someone good experiences to share? In lambdaprobe there are some info avail...
I'm using JMX to save some diagnostic information from a remote process. Looking at the interface in jconsole shows that the return type is CompositeData (the data actually comes back as CompositeDataSupport). I want to output all the key/value pairs that are associated with this object. The problem is that the interface just seems to h...
I am using Spring 2.5 and Java 1.6.0_7. I remote several JMX MBeans and have multiple clients invoking those MBeans remotely using JMXMP. I rely on JMX Notification listeners to push events out to multiple clients. I am trying to figure out how to secure remote access to those MBeans using Spring Security. I need to specify multiple le...
For a particular segment of Java code, I'd like to measure: execution time (most likely thread execution time) memory usage CPU load (specifically attributable to the code segment) I'm a relative Java novice and am not familiar with how this might be achieved. I've been referred to JMX, however I'm not sure how that might be used, an...
Here are the specs that I'm trying to implement in a nutshell: 1) Some Alerts have to be sent on certain events in the application. 2) These Alerts have Users subscribe to them. 3) And the Users have set their own Notification preferences (e.g. Email and/or SMS). I have not been able to find an open source solution in Java so far. I...
If you return a double or float from your MBean jconsole seems to round it down to the nearest integer. ...
all the examples I see are for J2SE applications by passing your JAR file at the command line. Can JConsole attach to a WAR or EAR and monitor application performance? ...
We are experiencing some slowdowns on our web-app deployed on a Tomcat 5.5.17 running on a Sun VM 1.5.0_06-b05 and our hosting company doesn't gives enough data to find the problem. We are considering installing lambda probe on the production server but it requires to enable jmx (com.sun.management.jmxremote) in order to obtain memory a...
I am currently tasked with developing a tool to use JMX to monitor JVMs for things like, but not limited too, memory usage, heap size, thread count. The desired tool is one that can display many graphs for each jvm next to each other (example below). So the question is it best to build your own? Use another tool that is out there? (i...
I am currently starting my Java VM with the com.sun.management.jmxremote.* properties so that I can connect to it via JConsole for management and monitoring. Unfortunately, it listens on all interfaces (IP addresses) on the machine. In our environment, there are often cases where there is more than one Java VM running on a machine at t...
We've added performance measures to our application and are exposing them using JMX. Now we would like to gather and store performance data for analysis, in files or in a database. Does anyone know of a JMX client, open source or commercial, that can persist gathered information? ...
I would like to find out what the properties of the org.springframework.ManagedResource annotation do as seen in this JavaDoc. I want to understand each param so I can set it to the proper value. If anyone knows where to find more info, I would appreciate it. http://static.springframework.org/spring/docs/2.5.x/api/org/springframework/...
While there appears to some documentation on how to expose JMX through various firewall and tunneling schemes, I sort of want the opposite. I want to ensure that JMX is only accessible to local machine. Unfortunately it appears that the "out of the box" management options do not allow restricting the ports to a local interface and nets...
I would like to use JConsole to monitor my Websphere application, but I am not sure how to enable JMX. ...
Hello, I have a Java app running on Tomcat, and I would like to monitor counters using Windows Performance Monitor. Is this possible using a JMX adapter for the Java MBeans or by some other means? ...
I've got some MBean operations that I need to secure. I would like the users to be required to log in as the server admin and I would like this to be setup programmaticly or, preferably by a config file in the WAR, when the app is deployed. I want to avoid requiring the admin to set this up as a deployment step. We're running glassfish...
