Jboss monitoring - No 'jboss' MBeanServer found!

manishdevraj Feb 25, 2013 10:03 AM

We are trying to configure Jboss monitoring using Nagios Plugin. We have installed Nagios server nagios-3.4.4 and plugin nagios-plugins-1.4.16. Jboss AS 7.1.1 configured Mbean server (SAR) to accept request at 5566 using MXbean.

When we try to run following command we are recieving follwing error.

$ sudo ./check_mbean_collector -H 10.0.11.232 -p 5566 -m jboss.system:type=ServerInfo -a ActiveThreadCount -w 200 -c 400

UNKNOWN ? UNKNOWN - MBeanServer responded: IllegalStateException No 'jboss' MBeanServer found!

It is throwing error at MBeanServer mbeanServer = MBeanServerLocator.locateJBoss();

I researched about issue and issue might occur if this call is made outside Jboss JVM, which is not the case currently as we are running collector.SAR on Jboss.

Any thoughts?

manishdevraj Feb 26, 2013 5:13 AM (in response to manishdevraj)

Above problem is dueto locateJboss implementation that is compatible with older version of Jboss. The MBeanServer used by JBoss 7 (by default) is the platform MBeanServer. The class name iscom.sun.jmx.mbeanserver.JmxMBeanServer and the default domain is DefaultDomain. Accordingly, you can simply use:

java.lang.management.ManagementFactory.getPlatformMBeanServer()

Alternatively:

     for(MBeanServer server: javax.management.MBeanServerFactory.findMBeanServer(null)) {
          if("DefaultDomain".equals(server.getDefaultDomain())) return server;
     }
     throw new Exception("Failed to locate MBeanServer");

On another note, jboss.system:type=ServerInfo object name doesn't work in AS 7.1 I had to use JVM specifi parameters to nail down to MBean attributes. 'java.lang:type=Memory' and attribute as 'HeapMemoryUsage'

For those looking for monitoring Mbean compatible with AS 7.1.1, I have pushed code to calculate Heapusage and prepared SAR to notify it to Nagios plugin. https://github.com/manishdevraj/jboss2nagios

Manish,

Thank you for the new file. I'm trying to monitor jboss AS7 using nagios and failed. I've also tried the new sar file which showed me the below errors. Can you help me to find out the reason?

Can you open the sar file with a normal unzip program?

Looks like SAR got corrupt when you downloaded. I re-downloaded it from GIT and I was able to open up in unzip. Confirm if you are able to open it? Also make sure you add dependency https://github.com/manishdevraj/jboss2nagios/blob/master/module.xml module.

Nope:

a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on

Hi Manish,

I got the correct file now.

[jboss7@dev20 ~]$ cksum collector.sar
363850209 12218 collector.sar
[jboss7@dev20 ~]$

Do I also need to add the jar file "jboss-common.jar" in to the deployment directory?

Manish,

From what I see with the existing installation, I've to copy the jboss-common.jar and module.xml files to "<JBAS7>/modules/com/jboss/jboss2nagios/". Let me try it out and will update you.

Take latest SAR it is built with dependency com.jboss.jboss2nagios module dependency. Also make your that you add package dependency "org.jboss.util.StringPropertyReplacer" in your standalone.xml once you create module. Restart JBOSS and you should be good.
