Supported IBM JVM #295

Closed EdouarL closed 3 years ago

EdouarL commented 3 years ago

Hi team,

Not supported for this JVM I try to connect to remote JMX running on IBM JRE and I got a message : Not supported for this JVM

Target JVM : 

C:\ibm-jre\jre\bin>java -version
java version "1.8.0_261"
Java(TM) SE Runtime Environment (build 8.0.6.15 - pwa6480sr6fp15-20200724_01(SR6 FP15))
IBM J9 VM (build 2.9, JRE 1.8.0 Windows Server 2016 amd64-64-Bit Compressed References 20200724_452227 (JIT enabled, AOT enabled)
OpenJ9   - 4ce4b9d
OMR      - 08b0594
IBM      - 70917a2)
JCL - 20200720_01 based on Oracle jdk8u261-b13

As documentation say : https://visualvm.github.io/relnotes.html

Required Software: Oracle JDK 8~16 OpenJDK 8\~16

so I guess it is not a bug any workaround to can use visualvm on IBM JRE will be appreciate

Please find enclosed screenshot and logfile Thanks jvisualvm_logfile-1.txt visualVM

many thank for your help, regards, Ed

Don't know if this helps but I'm using VisualVM for monitoring IBM WebSphere 8.5.5.x jvms which are Java 1.8 currently and all I need in simplest form (no authentication, no SSL - for more complex setup I use various configuration files and it's little but pain in the a*s to get it working) is to provide IBM jvm process with params

-Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=9000

Where the 9000 in the -Dcom.sun.management.jmxremote.port is the port you will connect your VisualVM to.

The RMI connection URL I enter into VisualVM Connection field is then service:jmx:rmi:///jndi/rmi://targethost:9000/jmxrmi in my case but that's WebSphere, not sure if same applies to your case

Thank you Pavel,

I tried your configuration, unfortunately it's not working for me. The jmx configuration (on target side) is done through Cognos following the documentation. And it's working fine on local with JConsol (with or without credential).

Thank you again for your help regards, Ed

I connected successfully from remote computer on my target server with JConsole :

But with visualvm I still get error

I cannot figure what is it about. Any help will be apreciate because Google help on this time. Thank you Ed

IBM JVM can be monitored via JMX just fine. You just need to start IBM JMV with enabled remote JMX monitoring. JMX documentation is available here. If JMX is set up correctly, you can attach to it from VisualVM by specifying host:port. Your JMX connection string looks strange to me and it looks like you are trying to connect to some kind of 'proxy JMX service'. This does not work well, since the proxy MXBeans do not have correct ObjectName. In your case the ObjectName for RuntimeMXBean should be java.lang:type=Runtime, but it is java.lang:dispatcher="xxxxxxxxx",type=Runtime. How did you enabled JMX? Where did you get this JMX proxy connection string? Is IBM JVM running on your local machine? Can you provide steps to reproduce?

Hello thurka,

thank you for your reply. JMX is enable with IBM Cognos Analytics (which is a BI application). I follow the official documentation to enable JMX : https://www.ibm.com/docs/en/cognos-analytics/11.1.0?topic=metrics-monitoring-system-externally

Here the way to enable JMX monitoring in Cognos (just give a port, if it 0 then it's disable) image

So maybe it is not IBM JVM related but more on application (?) it is the IBM Cognos which wrote to use the specific connexion string : service:jmx:rmi://Content_Manager_server/jndi/rmi://monitoring_server:/proxyserver

When I connect remotely or locally with JConsole it's ok (as shown in previous screenshots) But with VisualVM I got the error : Not supported for this JVM

image

image

I guess I am able to connect to the JMX because the icon associate to the connexion is colored

I also try to connect with a simple host:port connexion string without success as you can see the connexion is not working

regards,

It looks like IBM Cognos JMX connection (service:jmx:rmi://Content_Manager_server/jndi/rmi://monitoring_server:/proxyserver) does not provide ordinary JMX beans, but some kind of proxy JMX beans. VisualVM and JConsole works the same in this situation - there are no monitoring info. JConsole has all the monitoring tabs (Overview, Memory, Threads, Classes, VM summary) disabled and VisualVM displays 'Not supported by this JVM'. JConsole shows MBeans browser, which just displays exported MBeans without any interpretation. If you are interested to see same MBeans browser in VisualVM, just install VisualVM-Mbeans plugin.

host:port connection does not work, since the IBM Cognos JMX settings enables that 'strange' JMX connection service:jmx:rmi://Content_Manager_server/jndi/rmi://monitoring_server:/proxyserver. If you want to try to use ordinary host:port connection, you need to enable it first. You can try to follow this blog to see how to enable ordinary JMX monitoring.

Hello Thurka,

then this is definitely an issue on IBM Cognos side. I was able to find a problem with an IBM® program is documented, tracked, and not yet corrected : https://www.ibm.com/support/pages/apar/PH30864

Many thank for your help ! kind regards, Ed

I cannot access the link, since it requires IBMid. BTW: Did you try to enable ordinary JMX via blog post referenced above?

EdouarL commented 3 years ago

Here a screenshot of the link

I didn't try the blog post because I assumed it is a former version of the software

Issue was open with 11.1.7 IBM Cognos version. Bug is still there with 11.2.0
